Cobalt drill bits are often more expensive than other drill bits, but if you regularly drill through metal, they are a good investment since they tend to last longer. You can buy sets of drill bits in graduated sizes or individual drill bits for your specific needs.

physical vapor deposition coatings can not only resist high temperatures but also can be hard and stiff enough to avoid damage from high temperatures or impact to the surface of the tungsten carbide turning inserts.

Cemented carbide is a tool material made of refractory metal carbide and binder powder. The most widely used refractory metal used in industry is tungsten carbide. And the binder powder usually is cobalt powder and sometimes nickel or iron powder. Cemented carbide products are made by powder metallurgy, through mixing, milling, compacting, and sintering. After sintering, cemented carbide green compact will become stronger, harder, and get more properties, like wear resistance, corrosion resistance, and so on.

Physical vapor deposition is also called PVD in short, which is a vaporization technique to deposit a thin layer of material on the tungsten carbide turning inserts. It always has four steps, evaporation, transportation, reaction, and deposition. This process will happen in a vacuum chamber and uses clean and dry vacuum deposition. By physical vapor deposition, the coating film can be deposited on the surface of tungsten carbide turning inserts simultaneously. The method of physical vapor deposition can realize sputtering, ion-plating, magnetron sputtering, and electron beam sputtering. This process happens at the atom level.

Tungsten carbide drill bits are manufactured with a very thin layer of titanium nitride (TiN) to the whole surface of the carbide drill so that it will last far longer. The method known as “physical vapor deposition” is the one that is used for the application of titanium nitride the vast majority of the time (PVD). During the physical vapor deposition process, a vacuum-sealed container containing solid titanium nitride is positioned next to the drill. Titanium nitride “sublimates” when it is heated in an environment with extremely low pressure, such as a vacuum. This means that it goes immediately from a solid state into a gaseous one. Meanwhile, individual molecules of this gas are gradually adhering to the outside of the drill until its whole is coated in a layer that is both robust and very thin.

During finishing, CNC grinders are used to create high-quality metal workpieces for camshafts, ball bearings, drive shafts, and other work items that require precision and precision machining. This includes camshafts, ball bearings, and drive shafts. The grinding process used in CNC machines removes material using grinding wheels, grinding points, or abrasive cloths.

The inverted tapered structure has a shank at one end of which the structure is located. On the outer surface of the body, there are two helical grooves, which combine to form two helical flanks. As one moves from the nose of the body to the shank of the body, the radius of the helical flank gradually decreases.

The coating by physical vapor deposition can be harder and have better performances than other coatings like electroplating. So this kind of coating can last for a longer time.

Different types of drill bits are used to cut holes in different types of materials. Diamond drill bits are used for materials such as glass and tile; black oxide bits are common for plastics and carbon. Cobalt drill bits are particularly successful in cutting through hard metals such as stainless steel and cast iron, although they can be used for softer materials, too. Cobalt drill bits are not made of pure cobalt, but rather a steel alloy with 5 to 8 percent cobalt. The 5-percent alloy is known as M35 grade, and the 8-percent alloy is M42. The cobalt increases the strength of the steel and makes it more heat-resistant; this is an important factor in drilling hard materials because the friction of metal against metal can produce high temperatures that damage the material or the drill bit. Bosch, for instance, makes a cobalt drill bit that can withstand temperatures of up to 1,100 degrees Fahrenheit (593 degrees Celsius).

physical vapor deposition can be applied to many kinds of materials, not only tungsten carbide, and also plenty of inorganic and organic materials that can be coated on the materials.

The process of physical vapor deposition always happens in a vacuum environment. And it will not generate hazardous gases or products.

Tungsten carbide drill bits will be tested and validated. Testing, and process packages, are specifically designed to add maximum value to clients' evaluation and production activities, which requires a high level of expertise in the manufacture of carbide drills and extensive experience in high-quality manufacturing operations.

New cobalt drill bits are a dull gold color, making them distinctive on the shelf (or in your toolbox). The color occurs when the drill bits are baked in the process of production; it’s not a paint or plating -- cobalt drill bits are cobalt alloy through and through. For this reason, they can be sharpened relatively easily with cutting fluid while retaining their strength and durability (although the gold color may wear off).

Tungsten carbide drill bits used for drilling are typically composed of a steel shank and have a carbide tip. Because of their exceptional strength, they are frequently utilized in a variety of industrial applications. They are able to slice through a variety of materials, including tile, concrete, and masonry.

The passivation process of cemented carbide drills is a method to improve the corrosion resistance of cemented carbide parts. This is accomplished by removing ferrous contaminants, such as free iron, from the surface of carbide parts, restoring them to the original corrosion specifications they were designed to withstand.

The method of cylindrical grinding is to use a grinding wheel to rotate around a horizontal axis to cut or grind a cylindrical workpiece. When the grinding process is about to start, you have to reciprocate with the workpiece as it is fed into the rotating grinding wheel. You can adjust the depth of the cut by moving the wheel head closer to the part you are working on.
