Drill Bits

Cut holes in a variety of metals, from the softest aluminum to the hardest steel.

Cobalt Steel Jobbers' Length

Round Shank

Split

The toughness and wear resistance of cobalt steel in a length that's rigid enough for most applications. Cobalt lasts at least twice as long as high-speed steel. It can also run up to 25% faster at higher temperatures without damaging the bit on hard materials such as nickel.

Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on tough materials like hardened steel and nickel.

Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.

Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.

Cobalt Steel Short Length

Round Shank

Split

Combine the toughness and wear resistance of cobalt steel with a short length for drilling the straightest holes. These last twice as long as high-speed steel and can run up to 25% faster at higher temperatures without damaging the bit on hard metals like nickel. Also known as screw-machine and stub-length bits, they fit in tight spaces where longer bits can't.

Titanium Nitride (TiN) Coated—Drill at higher speeds and last longer than uncoated bits, especially on tough materials like hardened steel and nickel.

Uncoated—Polished to eject chips, these are also known as bright finish bits.

Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.

Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.

Chip-Clearing Drill Bits

With flutes that lift chips out of the hole, you don't have to stop drilling to clear these bits manually. The flutes improve coolant flow to dissipate heat and prevent clogs that can damage the bit and ruin the hole.

Cobalt Steel Jobbers' Length

Parabolic Flute

Split

Uncoated—Polished to eject chips, these are also known as bright finish bits.

Parabolic Flute—A U-shaped groove on the flutes cuts faster and clears chips more quickly than high-helix bits, so these are better for drilling deep holes.

Round Shank—The most common shank type. These fit in the chuck of drill presses and portable drills.

Split Point—Starts cutting on contact so you don’t need a pilot hole. The point also keeps the bit centered for straight and accurate holes, even with a portable drill.
