Just twist the collar ring and these tools will change from a standard cordless drill to a hammer drill.

The rotary-only mode is for general purpose drilling and driving fasteners. Use this mode with standard drill bits for wood and metal as well as masonry drill bits. In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. The hammering action pounds concrete and masonry, which breaks up the material while it drills. Use this mode for drilling masonry materials using carbide-tipped masonry drill bits.

This drill has a variable speed motor—the further you depress the trigger, the faster the drill rotates. They also have an adjustable clutch that lets you adjust the torque.

See Batteries and Chargers for Milwaukee Cordless Tools for replacement batteries and chargers.

These tools deliver powerful rotational blows to maximize torque and drive screws quickly, even through thick or dense material. Some drivers include rechargeable batteries that provide power wherever you need it. For other drivers, batteries and chargers are sold separately.

Drill multiple hole sizes using only one bit. These have steps with progressively larger diameters—the deeper they drill, the bigger the hole. Count the steps as you drill to achieve the proper size. These bits also deburr as they cut, so they're good for thin materials like sheet metal and plastic panels. Wear and heat resistant, high-speed steel is versatile for use on a range of materials.

Combine the precision of a drill press with the portability of a drill guide. These drill bases stabilize the Milwaukee electric drill model 0299-20 for perfect 90° holes. Magnetize these to any iron or steel surface with the flip of a switch. You can even secure these bases to walls and ceilings, and the magnet won’t slip until you turn the power off.

A powerful and durable hammer mechanism lets you drill deeper, larger holes in masonry and concrete in less time than with hammer drills. Also known as a SDS-Plus rotary hammer, this model is lightweight and ideal for overhead work and drilling smaller holes. Use with SDS-Plus drill bits. Note: SDS-Plus and SDS-Max bits are not interchangeable.

Use the rotary-only mode for general purpose drilling and driving fasteners (requires a chuck adapter or a magnetic bit holder). In rotary-percussion mode, the tool provides both a rotary drilling and hammering action. In the percussion-only mode, the tool provides only the hammering action. Use this mode when working with chisels and other masonry tools (see Chisels for Rotary Hammers).

This model has a variable speed—the further you depress the trigger, the faster the speed.

These drills work with hollow-core cutters to cut only on the periphery of the hole and produce a solid slug. This allows for a faster and easier cut than drilling with standard drill bits. Also known as magnetic core drilling machines.

They have a feed handle that mounts on the left or right side of the drill. The magnetic base attaches to flat ferrous surfaces (such as steel and cast iron). Holding force (also called drill-point breakaway) is calculated against a 1" thick steel plate.

Power through tasks that would be tedious with a manual driver. These screwdrivers tighten and loosen screws quickly and with minimal effort. They're ideal for repair shops and other high-volume jobs where efficiency is key. Charge the batteries to work in remote areas without power.

Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.

Get a better angle when drilling into hard-to-reach spaces.

Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.

Switch between drilling and driving bits in seconds. These keyless chucks require only a quick twist of their sleeve to lock and release bits. Most often used in handheld power drills, they're a great choice for most drilling and fastening jobs, including low-torque, high-speed drilling in soft or thin materials.
