The TiN coating on these drill bits protects them from wear and heat when drilling steel, stainless steel, and aluminum. Cobalt drill bits tolerate higher drilling speeds and are harder and more wear-resistant than high-speed steel drill bits. They provide some shock absorption and can be used in handheld power tools. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

The TiAlN/AlCrN multilayer coating on these drill bits protects the bits from wear and extends their life when drilling steel and cast iron. As one layer of the coating wears down, a new layer is exposed. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

These drill bits come in standard sizes expressed in millimeters. The bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

These drill bits come in standard letter sizes. The letter size for each bit indicates its compatibility with other tools that have the same letter size. The bits have a black-oxide finish that retains lubricants to improve the bits' wear resistance and chip flow. Black-oxide bits should only be used for drilling ferrous metals. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.

These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Coolant-through drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

The EgiAs coating on these drill bits resists oxidation at high temperatures and provides excellent hardness and heat resistance. The coating protects the bits from wear in high-speed drilling applications with steel, cast iron, and hardened steel with a Rockwell hardness of 35 to 50 HRC. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

These drill bits have a shank with a tang that prevents the bits from slipping in a drill chuck. Tang-shank drill bits can be securely inserted and removed from a compatible chuck without using tools, reducing downtime. These bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece. Carbide-tipped drill bits have carbide cutting edges that provide excellent hardness, wear resistance, and heat resistance and retain their hardness better than high-speed steel or cobalt cutting edges. The bits' bodies are made from a material that absorbs more vibration and shock than carbide. These bits have a bright finish that is not affected when their cutting edges are resharpened.

Coolant-through drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling tasks. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder. Carbide-tipped drill bits have carbide cutting edges that provide excellent hardness, wear resistance, and heat resistance and retain their hardness better than high-speed steel or cobalt cutting edges. The bits' bodies are made from a material that absorbs more vibration and shock than carbide. These bits have a bright finish that is not affected when their cutting edges are resharpened.

The TiNAl coating on these drill bits provides a low-friction surface on the tool and is suitable for drilling most materials. High-speed steel drill bits provide more flexibility and absorb more shock and vibration than cobalt and carbide drill bits, making them suitable for use in manual drilling machines and handheld power tools. They may leave a rough finish on the hole. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
