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.

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.

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.

Carbide-Tipped Steel Jobbers' Length

Round Shank

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.

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.

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.

Cobalt Steel Jobbers' Length

Spiral Flute

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.

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—Easier to start holes and stay centered than standard-point bits.

Precise-Cut Drill Bits for Wood

The sharp center point keeps these bits from wandering during drilling to cut accurate straight and overlapping holes, even across the grain. Also known as brad-point bits.

Brad Point—In addition to the center point, these bits have two cutting edges that make clean holes, often for installing dowel pins and other hardware.

Round Shank—Fit in the chuck of drill presses and portable drills.

High-Speed Steel—Wear and heat resistant, these bits are versatile for use on a range of materials.
