Drill Bits

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

High-Speed Steel Jobbers' Length

Round Shank

Standard

Split

Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.

Black Oxide—The dark finish increases wear resistance and reduces friction to improve chip flow, so these bits can last 50% longer than uncoated bits.

Gold Oxide—Like black oxide, this finish adds wear resistance and reduces friction for improved chip flow. Because it’s less prone to flaking off, it offers better rust protection when bits aren't in use.

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

Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're also known as bright finish bits.

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

Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

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 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.

Titanium Aluminum Nitride (TiAlN) Coated—The hardest and most wear-resistant coating, especially at high temperatures. These bits are best for hard and abrasive materials, such as iron, titanium, and fiberglass.

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.

Carbide-Tipped Steel Jobbers' Length

Round Shank


Standard	Split

The performance of solid carbide but at a lower price point. These jobbers' bits have the balance of rigidity and length needed for most applications. Like carbide bits, they are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.

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

Standard Point—Good for general purpose drilling. You’ll need to make a pilot hole to center the bit.

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.

High-Speed Steel Jobbers' Length

Parabolic Flute

Our basic drill bit material is also the most versatile. These jobbers' bits have the balance of rigidity and length needed for most applications.

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

Uncoated—The most economical option, uncoated bits perform best when used on low-carbon steel and aluminum. Polished to reduce friction, they're 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.

Drill Bits for Hardened Steel

Straight flutes withstand the heavy pressure needed to penetrate hardened steel. These bits cut more aggressively and resist stress better than spiral-flute bits.

Carbide-Tipped Steel Jobbers' Length

Straght Flute

The performance of solid carbide but at a lower price point. These jobbers' bits have the balance of rigidity and length needed for most applications. Like carbide bits, they are extremely stronger and maintain their sharp edges when drilling abrasive material. But for the longest life, there is no beating carbide.

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

Notched Point—The chisel-like point keeps the bit centered and clears chips.

Left-Hand Drill Bits

With flutes that spiral in the opposite direction of other bits, these are primarily used to remove stripped screws. Choose a bit that’s slightly smaller than the diameter of the screw’s head. Set your power tool to rotate in reverse. Slowly drill in the center of the screw head, maintaining constant pressure. As the bit penetrates, it will catch onto the screw and reverse it out of the hole. If the screw is badly stripped, you might need to punch a starter hole. Also known as reverse-flute bits.
