These jobbers'-length bits have the rigidity and length required for most applications.
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.
The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.
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.
Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length 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.
The parabolic spiral flutes lift chips out of the hole, reducing clogging and improving coolant flow.
Drill long, straight holes with these bits. Channels in the bit allows coolant to flow through the tool for more efficient chip evacuation. Also known as gun drills.
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.
Access hard-to-reach spots and drill deep holes.
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.
Use these bits for general purpose drilling in most material.
The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.
These bits have a round or hex shank that fits into the three-jaw chuck on a hammer drill.
Drill holes up to 1 1/2" in diameter.
These bits allow you to easily switch to another size by changing only the bit body. They are hollow and cut with their outside edge for drilling holes larger than 1 1/2" in diameter.
These hollow bits cut with their outside edge for drilling holes larger than 1 1/2" in diameter.
Also known as A-taper bits, these fit rotary hammers with a taper-shank chuck.
A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.
The 1/4" hex shank allows these bits to be used with standard impact drivers.
Use these diamond-coated hollow bits for wet drilling of masonry, concrete, and rebar with a drilling rig.
Use these bits with handheld power drills, drill presses, and hammer drills.
The SDS-Max shank has three deep slots and two shallow slots for use with SDS-Max-drive rotary hammers.
The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers set to rotary-only mode.
Use these bits with handheld power drills and hammer drills set to rotary-only mode.
A built-in stop ensures repeatable drilling depths for installing drop-in anchors.
Multiple outlining teeth bore clean, flat-bottom holes without chipping or splintering your surface—even when cutting across the grain. Also known as multispur bits.
Bore clean, flat bottom holes in soft wood, veneer, and laminates.
Also known as spade bits, these have a centering point and two cutting edges for boring holes in hard and soft wood.
Cut a variety of hole sizes with one bit—slide the blade to the desired cutting diameter marked on the bit and then tighten the screw. Use in a drill press; they are not recommended for use with handheld drills.
These bits are cut to match a wood screw’s thread and diameter, resulting in a perfect fit for a screw. They produce clean edges when cutting soft and hard wood.
The sharp point allows for gradual penetration to reduce friction and eliminate cracking and chipping when drilling in plastic.
The spear-shaped point drills smoothly through glass and ceramic.
Harder, stronger, and more wear resistant than high-speed steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
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.
Multiple cutting edges on the tip allow these bits to drill quickly through natural stone, granite, and other hard, abrasive material.
Use for drilling in most metal.
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.
Place a washer with an ID of the desired hole size over the bit and it acts as a stop to prevent the bit from drilling a larger hole.
Harder, stronger, and more wear resistant than cobalt steel, solid-carbide bits maintain their sharp edges longer. They require rigid toolholding to prevent breakage and should not be used in hand-held drilling applications.
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.
Unlike traditional wire-installing drill bits, you do not need to strip the end of the wire when using one of these bits. After drilling, insert the wire into the bit's hollow shaft and pull through the hole.
Insert directly into power screwdrivers, impact drivers, and other tools that accept a 1/4" hex shank.
The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit.
A more controlled chip removal reduces heat buildup. Use these bits on brittle materials such as block and brick.
Drill holes using simultaneous rotary and hammering action to break masonry material into tiny granules.
Bore smooth-finish, flat bottom holes in soft wood, veneer, and laminates. Also known as Forstner bits.
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.
Steps with progressively larger diameters let you drill a range of sizes with one bit. Also known as step drills.
Drill small holes by hand.
