About Drill Bits

Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications.

Chip-Clearing Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications.

Drill Bits for Precise Holes

Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Also known as double-margin drill bits.

Cobalt Steel Drill Bits

Short-Flute Cobalt Steel Drill Bits

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.

Chip-Clearing Cobalt Steel Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Carbide Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications.

Quick-Change Carbide Drill Bits

Make fast bit changes—all of these bits have the same shank diameter, eliminating the need for different collets to hold each size.

Smooth-Finish Carbide Drill Bits

Three cutting edges instead of the typical two enable these bits to drill holes with a smoother finish than other bits.

Carbide Drill Bits with Coolant Holes

Holes in these bits allow coolant to be run through the tool for more efficient chip evacuation. Use them in CNC machines with coolant-through technology.

Carbide Drill Bits for Precise Holes

Specially-designed flutes keep these bits centered as they drill, resulting in straighter, rounder holes with tighter tolerances. Also known as double-margin drill bits.

Chip-Clearing Carbide Drill Bits

The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.

Carbide-Tipped Drill Bits

These jobbers'-length bits have the rigidity and length required for most applications.

Nonsparking Drill Bits

Drill safely in flammable environments. Made of Factory Mutual (FM) approved beryllium copper, these bits won’t create sparks that could ignite if they made contact with combustible vapors or residues.

Hex-Shank Drill Bits

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.

Cobalt Steel Hex-Shank Drill Bits

In addition to resisting heat and wear better than high-speed steel drill bits, these can also run up to 25% faster and have a longer tool life. Insert them into power screwdrivers, impact drivers, and other tools that accept hex shanks.

Carbide-Tipped Drill Bits for Hardened Steel

Carbide-tipped bits maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Drill Bits for Carbon Fiber, Fiberglass, and Graphite

These jobbers'-length bits have the rigidity and length required for most applications.

Drill Bits for Plastic

The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.

Cobalt Steel Drill Bits for Stainless Steel and Nickel

Cobalt steel bits are heat resistant and maintain their sharp edges when drilling hard material. They are for use in both hand-held drilling and machine-tool applications.

Drill Bits for Aluminum, Brass, and Bronze

Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.

Left-Hand Drill Bits

High-Speed Steel Left-Hand Drill Bits

Use for drilling in most metal.

Cobalt Steel Left-Hand Drill Bits

With better heat and wear resistance than high-speed steel, cobalt steel bits can run up to 25% faster and have a longer tool life.

General Purpose Drill Bit Sets

Drill Bit Sets

These jobbers'-length bits have the rigidity and length required for most applications.

Chip-Clearing Drill Bit Sets

Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.

Cobalt Steel Drill Bit Sets

Short-Flute Cobalt Steel Drill Bit Sets

The short flutes on these jobbers'-length bits provide increased rigidity for drilling straighter holes.

Carbide Drill Bit Sets

For the highest accuracy and longest tool life, these solid-carbide bits are harder, stronger, and more wear resistant than high-speed steel, cobalt steel, and carbide-tipped bits.

Quick-Change Carbide Drill Bit Sets

Make fast bit changes—each bit has the same shank diameter, eliminating the need for different collets to hold each size.

Carbide-Tipped Drill Bit Sets

More wear resistant than cobalt steel and high-speed steel, carbide-tipped bits maintain a sharper, harder edge at high temperatures for excellent performance on abrasive material, such as plastic. Because they aren’t as brittle as solid carbide bits, they can be used in less rigid setups, such as a hand-held drill.

Hex-Shank Drill Bit Sets

Insert these bits directly into power screwdrivers, impact drivers, and other tools that accept 1/4" hex shanks.

Left-Hand Drill Bit Sets

Also known as reverse-flute bits, the flutes spiral in the opposite direction of other bits. Use in counterclockwise drilling applications such as removing broken screws.

Drill Bit Organizers

Drill Bit Cases

Store and organize drill bits so they stay in good working condition and don't go missing.

Drill Bit Drawer Cabinets

Store multiple bits of each size. These cabinets have drawers marked with the sizes and decimal equivalents.

Compartmented Under-Mount
Drill Bit Drawer Cabinets

The drawer is divided into labeled compartments.

Under-Mount Drill Bit Drawer Cabinets

These cabinets have one undivided drawer.

Drill Bit Pouches

Attach these pouches to your belt to easily access drill bits while working.

Drill Bit Stands

These stands hold round-shank drill bits of different sizes. The holes are marked with the bit size and decimal equivalent.

Countersinking

Drill-Bit Countersinks with Drill Bit

These countersinks come attached to a high-speed steel jobbers’ bit.

Quick-Change Combination
Countersinking Drill and Screwdriver Bits

Drill, countersink, and drive screws without switching three separate bits in and out of your power tool.

Quick-Change Combination Countersinking
Drill and Screwdriver Bit Sets

Fasten differently sized screws with these sets. They save you the effort of switching three separate bits in and out of a power tool, instead letting you flip between a countersinking drill and a screwdriver bit with a single hand.

Drill-Bit Counterbores with Drill Bit

These counterbores are attached to a drill bit for drilling and counterboring in a single step.
