2 27/32" Long Drill Bits

Switch bits instead of tools to simplify jobs. These snap directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank. You can slide the countersink up and down the drill bit and then secure it with a set screw, so one tool will drill countersunk holes for screws of different lengths. These countersinks cut a smooth and even finish in wood and plastic on the first pass.

High-Speed Steel


2 Flutes	Depth Stops

These wear-resistant countersinks cut faster and last longer than carbon steel countersinks, so they’re often used for high-volume jobs. You can also use them on harder materials, such as steel and stainless steel.

Drill Taps

Spiral Flute

Drill holes and cut threads without switching tools. Made of high-speed steel, these taps are for use on most metal and plastic. The square shank is compatible with tap holders for drill presses and milling machines. All have a plug chamfer with 3-5 chamfered cutting threads, so they're suitable for start-to-finish tapping.

Uncoated High-Speed Steel—Uncoated taps are strong enough for most tapping jobs but have the shortest tool life.

Spiral Flute—Taps with spiral flutes keep chips clear by drawing them back toward the tap and out of the hole.

Carbide-Tipped Double-Chamfering End Mills


Double-Chamfering Cut Style

Made of carbide-tipped high-speed steel, these end mills provide a sharper, harder edge at high temperatures than plain high-speed steel. Because they aren’t as brittle as solid carbide, they can be used in less rigid setups, such as manual milling machines. The teeth are angled in two directions so you can make top and bottom chamfers without having to flip the workpiece.

Uncoated—Use uncoated end mills for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.

Titanium Nitride (TiN) Coated—Titanium nitride (TiN)-coated end mills create less friction than uncoated end mills, which means they last longer when run at similar speeds. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.

Titanium Carbon Nitride (TiCN) Coated—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.

Aluminum Titanium Nitride (AlTiN) Coated—Aluminum titanium nitride (AlTiN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
