To choose the best drill bits for metal and other materials, you should consider the design features that affect their performance. These are the three key design features of drill bits:

The drill point length refers to the distance from the tip of the drill bit to the beginning of the flute. There are three types of drill point lengths: standard, jobber, and long.

When it comes to drilling, there are various types of drill bits designed for specific materials and applications. Here are some of the most common types:

A bare metal finish with no coating. It is the most common type of drill bit. They are best used for drilling plastic, wood, and soft metals.

The drill point angle refers to the angle at which the cutting edge of the drill bit is ground. It is measured in degrees and can range from 90 to 150. A 118-degree angle is the most common, but other angles, such as 135 degrees and 90 degrees, may be more suitable for specific materials or applications.Common Drill Point Angles

When it comes to using drill bits, mistakes are not uncommon. These are some of the most common mistakes that you should avoid to ensure safety:

Carbide (Carb) drill bits are made from tungsten carbide, which is a dense and durable material that can resist high temperatures and wear. They are ideal for drilling through hard materials, including ceramics, glass, and masonry, as well as hard metals like stainless steel and cast iron.

Cobalt (HSCO) drill bits are made from high-speed steel with added cobalt, which enhances their strength and heat resistance. They can withstand higher temperatures and are less prone to dulling. Cobalt drill bits are ideal for drilling through hard metals, such as stainless steel, cast iron, and titanium.

A gold-colored coating that provides heat resistance and hardness. It is made by depositing titanium nitride on the surface of the drill bit.They are best used for drilling hard materials such as stainless steel, cast iron, and titanium.

EAGLE AMERICA Router Bits are the highest quality, American-Made premiere router bits in the industry. The Eagle America Brand was created for the professional woodworker who needs a serious router bit with an exceptional cut, extremely high durability and longevity.

A gray-colored coating that is harder than TiN. It is made by depositing a layer of titanium carbonitride on the surface of the drill bit. They are best used for drilling abrasive materials like high-silicon aluminum, fiberglass, and carbon composites.

EAGLE AMERICA Chamfer Router Bits are an American Made Premiere Router Bit. They are the perfect bits to make multi-sided boxes, planters, columns or beams.

MLCS PREMIUM Router Bits are top-quality imported bits guaranteed to meet or exceed any brand on the market. These impressive router bits feature micro-grain carbide for long life and multiple resharpening, anti-kickback design, a non-stick coating to prevent debris build-up, diamond-honed cutters, and an exclusive Safety Gauge shank.

Using the wrong bit can result in damage to the material, decreased efficiency, and even injury to the user. Therefore, it's essential to understand the various types of drill bits available and their unique features, including materials, coatings, point angles, and lengths.

MLCS Router Bits and router bit sets are the "Best of the Best" when comparing them to other value priced, imported brands. The MLCS Brand was created for the cost conscience woodworker who needs a quality router bit that has a very good cut, good durability, good longevity but still has a great price.

Black oxide is a coating made by blackening the surface of the drill bit to enhance rust resistance and reduce friction. It is made from iron oxide and magnetite. They are best used for drilling soft metals such as aluminum, copper, brass, and mild steel.

High-speed steel (HSS) is a type of tool steel that is highly resistant to heat and wear. It contains tungsten, molybdenum, chromium, and vanadium, which provide increased strength and durability. HSS drill bits are suitable for drilling into soft metals, such as aluminum and brass, as well as wood and plastic.

Each type of drill bit has its own unique features, suitable applications, advantages, and disadvantages. Choosing the right type of drill bit is essential for achieving accurate and efficient results in drilling.

One of the most important tools in any metalworker's arsenal is the drill bit. Drill bits are cylindrical cutting tools that are used to create holes in various materials such as metal, plastic, wood, ceramic tile, and concrete. But not all drill bits are made the same, and choosing the wrong one can lead to disastrous results.

Flutes are the grooves that run spirally along the length of a drill bit. They serve to remove chips and debris from the hole as the bit cuts into the material. They are also typically wider and deeper on larger diameter bits. Flute design can greatly affect the performance and efficiency of a drill bit.

Whether you're a seasoned metalworker or just starting, this guide will equip you with the knowledge you need to make informed decisions and achieve the best results.

MLCS BLUE ICE Router Bits are Solid Carbide Bits that are specially formulated nano-ceramic coating designed to reduce heat and friction on router bits. Because of this there will be less pitch and gum build up, cuts will be cleaner, carbide stays sharper, and the life of your bit will last up to 3x longer.

MLCS TRIPLE FLUTE Router Bits have an extra cutting blade (3 flute versus 2 flute) that saves time by allowing more aggressive cuts, and therefore, fewer passes. These bits can be run at reduced speeds, helping to eliminate burning on problem woods, such as, cherry and oak. They produce 50% more cuts per inch, for a smoother, cleaner result. These bits stay sharp and last 50% longer than standard 2 flute router bits.
