Adapt your rotary hammer to fit a variety of masonry drill bit shank types.

These arbor adapters are required when using Milwaukee hollow-core cutters. Also known as annular cutters.

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'- and maintenance-length drill bits.

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

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.

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

The short flutes provide increased rigidity for drilling straighter holes than standard extended-length drill bits.

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

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length drill bits.

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.

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

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.

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

Access hard-to-reach spots and drill deep holes.

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.

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.

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.

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.

The screw point draws the bit in, quickly boring holes without applying pressure.

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.

An open spiral-flute design clears chips quickly, so these bits can bore smooth, deep holes through construction lumber, railroad ties, and utility poles. Also known as pole or ship auger bits.

Harder, stronger, and more wear resistant than carbide-tipped 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.

These hollow bits cut with their outside edge for drilling holes larger than 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.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.

A more controlled chip removal reduces heat buildup. Use these bits on brittle material such as block and brick.

Drill holes up to 1 1/2" in diameter.

Adapt a bit for use on a drilling rig with a different thread size.

The SDS-Plus shank has two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers.

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.

Use these bits with handheld power drills and hammer drills set to rotary-only mode.

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.

When one end becomes worn, reverse the bit to use the other end.

These hollow bits are diamond-tipped for long life and fast cutting speeds. Only for use in drill presses.

Also known as screw-machine and stub-length bits, these provide maximum rigidity for drilling straighter holes than jobbers'-length 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.

The built-in guide has a beveled tip that fits into countersunk holes in hardware, such as hinges and latches, to center the bit.

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.
