Carbide is incredibly versatile. It can be combined with many different materials. It can be soldered, shrink-fitted, glued, screwed, clamped or pressed. In addition to suitable plastics, all metallic materials can be used.

Think about how often you’ll use the bits. For occasional DIY projects, titanium bits offer good value. They last longer than plain steel bits but won’t break the bank.

Titanium-coated bits work well for drilling softer metals, wood, and plastic. They’re cheaper than solid carbide but more durable than plain HSS.

For wood drilling, both titanium and carbide bits can be effective. Titanium-coated bits resist pitch and sap buildup, making them ideal for softwoods and pine. They also work well in plywood and other composites.

What is carbideused for

Carbides feature completely different UNIQUE properties to accomplish the greatest variety of goals. They can be fundamentally different depending on binder materials, binder content and grain size.

How can carbide be combined with other materials or products? The choice of the most useful fastening option is fundamentally dependent on the application of the respective workpiece. Tungsten carbide ultimately offers numerous options: i.e. soldering, gluing, shrink-fitting, casting or mechanical fastening.

Titanium coatings reduce friction during drilling. This helps the bits run cooler than uncoated steel bits. The coating also provides some heat resistance, but not as much as carbide.

Titanium bits work well for drilling into softer steels. They stay sharp longer than regular steel bits. Carbide bits outperform titanium when drilling harder steels. They can handle higher speeds and maintain their edge longer in tough materials.

Our carbide end mills are made of tungsten carbide, the performance, quality and lineup have been well established especially for sizes 12mm and below.

The degree of hardness is determined by the Vickers method The force of a 30 kg (294 Newton) weight is used to produce a measurable surface indentation in reference to a defined diamond. The degree of hardness of the tungsten carbide component increases with decreasing content of binding agent and decreasing grainsize.

Carbide drill bits last a very long time. Their extreme hardness means they wear down slowly, even when drilling tough materials. With proper use, carbide bits can last 10-20 times longer than standard steel bits.

Laser cutting is another game-changer. It makes super precise bits with very sharp edges. This is great for drilling tiny holes in circuit boards and other delicate work.

For high-speed drilling, titanium bits often perform better. Their coating reduces heat buildup, letting them run at higher speeds. Carbide bits are great for precise, slower drilling in tough materials.

When working with hardened steels, carbide is the clear winner. It can maintain its edge and drill accurately in these challenging materials.

Tolerance stack analysis is particularly important when there are separate teams responsible for designing and manufacturing a product. The analysis involves ...

We find titanium bits last longer in general use. But for specific tough jobs, carbide bits can outlast titanium. In wet conditions, carbide resists rust better than titanium-coated steel.

Before gluing tungsten carbide, the adhesion surface must be treated and mechanically roughened. The glues that we use feature a high thermal stability up to 200 °C. The material can be easily glued. In many cases, gluing is a good alternative to soldering. However, at higher temperatures, soldering is the only option.

These bits keep their edge at high temps. This lets them drill faster without losing sharpness. HSS bits are cheaper than other types, making them a good choice for home use.

Carbide bits can drill faster than titanium-coated bits. Their hardness lets them maintain a sharp cutting edge at high speeds. This makes them good for production drilling where speed matters.

Titanium drill bits are steel bits coated with titanium nitride. This coating makes them harder and more heat-resistant than standard steel bits. Carbide bits, on the other hand, are made from tungsten carbide. They’re much harder than titanium-coated bits and can withstand higher temperatures.

Tungsten carbide can be soldered to suitable steel components. Be sure the design of the carbide component includes an adequate structure for soldering. Also be aware that the thermal expansion of tungsten carbide is only about half that of engineering steel.

Both have their strengths. Titanium bits resist heat and corrosion well, making them great for everyday use. They’re also more affordable. Carbide bits, though pricier, excel at drilling through tough materials like masonry.

Titanium-coated bits work well on softer metals like aluminum. They reduce friction and heat, which helps prevent the bit from binding in the material. This makes them a good choice for drilling thin sheet metal.

Titanium bits tend to cost less than carbide ones. You can get a good set of titanium bits for around $20-$30. Carbide bits usually start at $40-$50 for a small set.

In numerous industrial processes, there are abrasive effects between different materials, resulting in premature wear of one of the two materials. Tungsten carbide provides – due to its versatility – ideal options to significantly reduce premature wear.

New materials are making waves in drill bit design. Ceramic bits are tough and can handle high heat. They work well for drilling hard metals.

Carbides are not created equal. The production time of a carbide tool, carbide component or carbide part depends greatly on size, desired geometries as well as quality. Therefore, production time cannot be generally stated – it is different and determined for each piece individually.

Titanium bits are usually HSS or cobalt bits with a titanium coating. This thin layer adds strength and reduces friction.

Tungstencarbide

Titanium-coated bits also have good wear resistance. The coating helps them last 3-6 times longer than uncoated bits. But the coating eventually wears off, especially when drilling hard materials.

Carbides can be coated using PVD or CVD processes. The PVD method with low coating temperatures around 450 °C is preferable to the CVD method with coating temperatures of 900-1,100 °C. Tungsten carbide is frequently used as a basis for coatings due to its high pressure resistance which prevents the egg shell effect when coating parts.

Carbide drill bits are the top pick for drilling concrete, tile, and other masonry materials. They can withstand the high heat and abrasion of these tough surfaces. For glass and ceramic, carbide-tipped bits designed for these materials work best.

Titanium drill bits are cheaper to buy at first. We can often find them for $20-$50 per set. Carbide bits cost more upfront, usually $50-$150 for a set. The higher price of carbide comes from its harder material and complex manufacturing process.

Think about the size of holes you need to make. Smaller bits (under 1/4 inch) come in both titanium and carbide. For bigger holes, carbide is often better but costs more. Match the bit size to your drill’s chuck size too.

Carbide drill bits excel at drilling hard metals like steel and cast iron. They stay sharp longer and can handle high-speed drilling in tough materials. For stainless steel, carbide bits offer better performance and longer life than titanium-coated options.

For daily use or tough jobs, carbide bits are worth the extra cost. They’ll stay sharp much longer, saving time and money on replacements.

Carbide production in a nutshell: Powder containing tungsten carbide and the chosen binder, is ground and mixed to achieve the desired composition. Subsequently it is dried. The resulting granulates are then pressed into shape. For this process, different methods of direct and indirect forming are available. The pellet, also called “green compact”, can then be processed mechanically. Finally, the part is sintered at about 1,300 to 1,500 °C.

Sharpen titanium bits with a standard grinder. Carbide bits need special diamond wheels for sharpening. Replace bits when they show signs of wear or damage to ensure the best results.

Titanium bits work great for drilling into softer materials like wood and plastic. They’re tough and stay sharp longer than basic steel bits. For harder materials like metal or masonry, carbide bits are the way to go. They can handle high heat and keep their edge.

Carbide bits handle high heat well. They can drill at higher speeds without losing their edge. The material stays stable even at very high temperatures.

The term “blank” or “carbide blank” refers to a workpiece that requires further processing. In tungsten carbide production, the blank is the part that emerges from the sintering process. For the powder mixture to become an actual carbide blank, it must be pressed in a mold. Good to know: DURIT blanks feature a VERY low grinding excess – perfect for subsequent processing.

In aerospace and medical applications, carbide bits are often used due to their precision and durability when working with titanium alloys and other specialty metals.

Carbide

Carbide drill bits are extremely hard. They rate 9-9.5 on the Mohs scale. This makes them very durable and able to drill through tough materials. Carbide bits keep their sharp edge longer than other types.

Cobalt drill bits contain 5-8% cobalt mixed with HSS. This blend makes them stronger and more heat-resistant than regular HSS bits.

Titanium and carbide drill bits have different strengths when it comes to drilling various materials. We’ll explore how they perform on metals, wood, composites, and specialty materials.

Choosing between titanium and carbide depends on your needs. For most home projects, titanium bits work fine. But for heavy-duty jobs or drilling hard materials, carbide might be the way to go. We’ll explore these differences more to help you pick the right bit for your task.

The main binder for carbides is usually cobalt, because it has a positive impact on the sintering process. If increased corrosion resistance is desired, a nickel-binder is the material of choice. The most common binding agents in today’s carbide production are Cobalt (Co), Nickel (Ni), Iron (Fe), and Nickel-Chromium (NiCr). In this context it is important to remember that the hardness of a carbide part increases with decreasing content of binding agent and decreasing grain size.

Cobalt bits cost more than HSS but less than carbide. They’re a good middle ground for pros who need extra strength without breaking the bank.

The hardness of tungsten carbide is determined in Vickers throughout Europe. The Vickers process is a static hardness test. Founded in 1828, Vickers Limited was an important British machine manufacturer and defense contractor. In the United States the Rockwell test (HRA) is preferred. Tungsten carbide actually offers a broad range of available hardness. It ranges from “soft” grades with a hardness of 770 HV30 to highly wear-resistant grades with a hardness of up to 2,000 HV30.

The hard metal material most commonly used is Wolframcarbide (WC), which is a high-performance material composed of Wolfram and carbon. Its defining characteristic is its hardness, which is close to the hardness of a diamond. Wolframcarbide is obtained from tungsten ores “wolframite” and “scheelite”. These are mined primarily in China, Russia, Canada, Austria and Portugal. The manufacturing process is called carburization, which is a metal treatment process that adds carbon to a metal surface with low carbon content – thereby increasing the hardness of the metal. Varieties of Wolframcarbide-Cobalt carbides are the most important in today’s market.

This longer life makes carbide more cost-effective over time, especially for heavy use. We save money on fewer replacements and less downtime changing bits. For light use, titanium’s lower upfront cost may still be the better choice.

Titanium bits are actually steel bits with a titanium coating. The coating is harder than steel but not as hard as carbide. Titanium-coated bits rate about 8.5 on the Mohs scale. They’re tougher than plain steel bits but not as durable as carbide.

Tungsten carbide components can be easily screwed. The thread in the carrier material should be included in the construction process. Depending on carbide grade the thread can also be cut into the final workpiece.

High-speed steel is a common drill bit material. It’s tough and resists wear. HSS bits work well for drilling into wood, plastic, and soft metals.

Titanium and carbide drill bits have distinct characteristics that affect their performance. These properties influence how well each type performs in different drilling applications.

Drill bits come in many types, but titanium and carbide stand out for their durability and performance. We often get asked which is better. Titanium drill bits are high-speed steel bits with a titanium nitride coating, whilecarbide bits are made from a mixture of tungsten and carbon.

For home DIY projects or occasional use, titanium bits may be more budget-friendly. But for frequent drilling or professional work, carbide’s durability can justify the higher cost.

3D printing is changing how we make drill bits. It lets us create complex shapes that were hard to make before. This means we can design bits that work better and last longer.

The balance of hardness, wear resistance and toughness makes carbide so special. The exact properties are determined by the composition. One decisive factor is the selection of grain size. That means: The finer the grain, the higher the hardness and wear resistance.

The flutes on titanium bits are often deeper, which helps clear away debris faster. Carbide bits usually have shallower flutes to maintain strength. Titanium bits come in more shapes and sizes, while carbide options are more limited.

We see titanium bits with gold or bronze colors from their coating. Carbide bits are typically silver or gray. The coating on titanium bits can wear off over time, while carbide keeps its properties throughout its life.

Titanium and carbide drill bits have key differences in their makeup and performance. Let’s look at how they compare in construction, applications, and care.

Titanium and carbide drill bits have distinct characteristics that affect their performance and suitability for different materials. Let’s explore some key questions about these two types of drill bits.

Compared to other materials, tungsten carbide distinguishes itself with an enormously high pressure resistance. Pressure resistance increases with decreasing binder content and decreasing grain size. Tungsten carbide grades with a low carbide grain size and a low binder content attain a pressure resistance of approximately 7,000 N/mm2.

Carbide is extremely multi-faceted in its application. The material impresses with its enormous versatility and provides a large number of advantages and features that make it desirable for use across multiple industries. For most DURIT customers, the following three features are the most important ones:

Picking the right drill bit is key for getting the job done well. We’ll look at how to choose bits that match your needs and budget.

We need to think about the material we’re drilling, how often we’ll use the bits, and our budget. Cobalt bits are great for stainless steel. Titanium bits are versatile and affordable. Carbide bits are pricey but last longest in hard materials.

Drill bit technology keeps getting better. New coatings, manufacturing methods, and materials are changing how we make and use drill bits.

Titanium bits work well for drilling into softer materials like wood, plastic, and mild steel. They stay sharp longer than standard steel bits. Carbide bits excel at drilling very hard materials like hardened steel, cast iron, and abrasive materials.

Look for deals on bit sets. Getting a mix of titanium and carbide bits can give you options for different tasks without spending too much.

Titanium drill bits are made from high-speed steel with a titanium coating. This coating helps reduce friction and heat during use. Carbide bits, on the other hand, are made from tungsten carbide. They’re harder but more brittle than titanium bits.

Carbide bits last longer when drilling hard metals. They can operate at higher speeds without losing their edge. Carbide also resists heat better than titanium coatings. This means carbide bits can drill more holes before needing replacement.

Titanium bits offer good cutting speeds too, faster than plain steel bits. The coating reduces friction, which helps maintain speed. But they can’t match carbide’s top speeds.

Some new coatings even “heal” themselves. Tiny cracks in the coating can close up on their own. This keeps the bit sharp and working well for a long time.

Yes. By using cobalt and nickel as binding agents, carbides inherit magnetic properties. A specific sintering method can greatly reduce the magnetic properties of nickel-bound carbides.

The technically correct term for the chalk-like powder pellet is “green compact”. The green compact already exhibits all geometric characteristics of the desired part. During the sintering process, porosity and volume are considerably reduced.

Carbides are sintered composite materials made of hard metal materials and a binding agent. They are usually made with a combination of tungsten carbide and cobalt (WC+Co). In addition to Tungsten (WC), also Titanium (TiC), Tantalum (TaC), Chromium (CrC) or other carbides are used as hard materials as well. Cobalt (Co), Nickel (Ni), Iron (Fe) and Nickel-Chromium (NiCr) are most frequently used as binding agents.

The main drawback is cost. Carbide bits are pricey, but they last much longer than other types. This makes them worth it for heavy-duty or high-volume work.

Titanium bits can handle some plastics and fiberglass, but may not last as long as carbide in these materials. For PCB boards and other electronic components, titanium-nitride coated bits reduce static buildup.

Carbide-tipped bits are great for hardwoods like oak or maple. They stay sharp through many uses and produce clean holes. For MDF and other abrasive materials, carbide bits last much longer than titanium-coated ones.

The question whether carbide conducts electricity can be answered with a resounding “yes”. Due to its tungsten carbide content, carbide is in fact a very good conductor. The average resistance is 20 µΩ/cm.

Carbide is a composite material. It consists of alloys made from hard metal materials, so-called carbides, and a metal binding agent.

Another cool coating is diamond-like carbon (DLC). It’s super hard and slick. This helps bits slide through tough materials with less friction.

Hybrid bits mix different materials. For example, a carbide tip with a steel body. This gives the best of both worlds – a hard cutting edge and a flexible shaft.

Siliconcarbide

When chemist Henri Moisson searched for a way to make synthetic diamonds in 1894, the expression “Wolframcarbide” (WC) was widely publicized. About 20 years later industrialists Hugo Lohmann and Otto Voigtländer finished their process to produce parts made of Wolframcarbide, which were sintered just below the melting point. In 1914 they patented their cast tungsten carbide, but failed to establish it in the marketplace, mainly due to its brittleness. That was not accomplished until nine years later, when Karl Schröter and Heinrich Baumhauer developed sintered tungsten carbide. Osram bought their patent in 1923. Industrial use beginning in 1926 got things going. Krupp Hartmetall successfully launched its material named “Widia” – as in diamond (German: “wie Diamant”) – in the marketplace. In the USSR tungsten carbide was developed under the name “Pobedit” starting in 1929 by a company bearing the same name.

Carbide bits are more durable than titanium-coated bits. They keep their sharp edge longer, especially in hard materials. Titanium bits wear out faster but are less brittle than carbide. This makes titanium bits less likely to break if dropped.

These bits excel at drilling through hard metals like stainless steel. They stay sharp longer and can handle higher speeds.

This is primarily determined by the geometry of the workpiece: Contoured parts can usually only be processed economically in green compact form. Due to shrinkage of the green compact in the sintering process, accuracy within one tenth can be accomplished. Round or standard geometric shapes can be processed with considerably higher precision of up to 3 µm.

Titanium bits work well for wood, plastic, and softer metals like aluminum. They’re a good all-purpose choice for DIY projects. Carbide bits excel at drilling hard metals, cast iron, and abrasive materials like fiberglass.

Drill bit materials play a key role in performance and durability. We’ll explore the main types and coatings used for different drilling needs.

Titaniumcarbide

Drill bit costs vary greatly between titanium and carbide options. The price affects both upfront spending and long-term value. Let’s look at how these materials compare financially.

In general, titanium bits are a good all-around choice for wood projects. Carbide bits are better for precision work or when drilling many holes in hard materials.

Some new designs have special flutes. These help remove chips better and keep the bit cool. Others have variable pitch flutes that reduce vibration and noise while drilling.

What carbide grades are used where? Remember: depending on composition and structure, carbide has very different properties. So far there has been no uniform systematization, typification or generally applicable technical term. At DURIT, we differentiate between the TWO TYPES GD and BD:

Sintering is a thermal process under anaerobic conditions. In carbide production, this process firmly embeds the tungsten carbides into a binding matrix. For this purpose, the binder in the green compact is heated to its liquid phase. It then fills the interstitial spaces and surrounds the carbides. The HIP sintering process includes an injection of argon at high pressure after reaching the liquid phase. This provides the carbide with additional density and ensures a homogeneous, non-porous structure.

Both types can drill precisely. Carbide’s hardness helps it stay sharp and true. Titanium’s reduced friction can help prevent wandering. For the most precise holes, carbide often has an edge.

Coatings are big news in drill bits. Titanium nitride (TiN) coatings make bits last longer and cut faster. They also help bits stay cool while drilling.

We recommend storing both types in a dry place. For titanium bits, avoid contact with other tools to protect the coating. Carbide bits should be kept in padded cases to prevent chipping.

Computer simulations help too. We can test new bit designs without making real ones. This saves time and money in developing new cutting tools.

Consider what you’re drilling into most often. If it’s mostly wood, titanium bits will do fine. For lots of metal work, invest in some good carbide bits.

Oxidation can certainly occur on the surface of any cobalt-bound carbide. This occurrence is in no way comparable to the corrosion we find in steel for example. The reason: The material structure is not destroyed to any extend.

Thermal shrink-fitting is the perfect fastening method for braced rotary tools in forming technology. The steel holder is heated to 450 °C to expand and subsequently, the tungsten carbide core is inserted.

The best coating depends on what you’re drilling. TiAlN works well for hard metals, while black oxide is good for general-purpose use.

These bits stay sharp much longer than HSS or cobalt. They can drill faster and handle higher temps without losing their edge.
