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	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.

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.

High-Speed Steel Extended Length


Parabolic Flute Round Shank	Split

Drill through walls and thick workpieces with our longest high-speed steel bits. Their length is good for creating deep holes but makes them less rigid than other bits. As a result, they are more prone to wobbling or breaking, especially when drilling hard materials.

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.

Cobalt Steel Jobbers' Length

Parabolic Flute

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.

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.

Carbide Jobbers' Length


Parabolic Flute	Standard

The hardest and most wear-resistant drill bits you can buy in a length that's rigid enough for most applications. These bits stay sharp at high temperatures and faster speeds for the best performance on hard and difficult-to-machine materials. They last 10 to 20 times longer than their closest alternative, cobalt steel. Carbide can be brittle, however, so these bits require a rigid machine tool holder to prevent breakage and should not be used in hand drilling applications.

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

Uncoated—Excellent for a range of metals, they perform best when used on steel, aluminum, brass, and bronze.

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 fits in a drill press chuck.

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

Chip-Clearing Drill Bits for Nickel and Stainless Steel

Excellent for challenging metals such as stainless steel and nickel alloys, these bits cut aggressively and evacuate chips quickly. The grooved flutes prevent clogs and improve coolant flow to dissipate heat that can damage the bit or your material.

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.

Chip-Clearing Drill Bit Sets

High-Speed Steel Jobbers' Length

Parabolic Flute

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.

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.

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.

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.

Tapping Screw Installation Drill Bits for Masonry and Concrete

Create an undersized hole so concrete tapping screws fit tightly once they're threaded into place. These bits are slightly smaller than the matching screw size. They have a carbide tip that resists wear and heat to stay sharp.

Round Shank for Hammer and Rotary Drilling

Use these bits in rotary hammers that have a drill chuck. Simultaneous rotary and hammering action drills faster and penetrates material with less pressure than rotary-only bits. Also known as percussion or impact bits.

Standard Point—The most common point type handles most jobs. However, for more aggressive cutting that generates a lot of heat, consider a multipoint or serrated bit.

Drill Bit Sets for Masonry and Concrete

Crush rather than cut material so bits don’t jam or overheat while drilling masonry and concrete. The ultra-hard carbide tip breaks masonry into pieces and the widely spaced flutes channel them out of the hole. These bits stay sharp, resisting wear and heat that will dull or break other bits.

Chip-Clearing Drill Bits for Wood

Prevent clogs that wear the bit and slow down drilling when it gets jammed. The flutes on these bits have an open design that pulls chips out of the hole faster than standard spiral flutes. Also known as pole or ship auger bits, they are used to cut deep holes through lumber, railroad ties, and utility poles.

Quick-Change Hex Shank—Switch bits instead of tools. These simplify jobs by snapping directly into power screwdrivers, drills, and other tools that accept a _1/4" hex shank.

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

Hex Shank—Secure in chucks that accept a hex shank. You can also cut the bit to expose a _1/2"round shank for use in other tools.

Tapered-Square Shank—Use with manual hand drills. You can cut off the square portion to expose a round shank to fit other tools.

Screw Point—Draws the bit into the material without the need to apply a lot of pressure.

Black-Oxide Steel—The dark finish reduces friction to clear chips more quickly than uncoated bits.

Nonstick-Coated Steel—Chips won’t stick to the bit, even when drilling in material that contains sap or glue.

Flexible-Shaft Drill Bits for Wire Installation


	Round Shank

Drill inside walls and between floors to install electrical wiring without cutting extra access holes. The shaft on these bits flexes for a long reach in any direction. To install wire, first strip the end and attach it to the small hole at the tip of the bit. Then pull wire back through the drilled hole. Also known as bell hanger bits.

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

Powder-Coated Steel—The dark coating protects against scratches and rust when you're not using the bit.
