7" Long Drill Bits | McMaster-Carr

Extended Length—Drill through panels and thick workpieces with our longest 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.

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.

Carbide-Tipped Drill Bits for Hardened Steel

Jobbers' Length

Round Shank

Straight flutes withstand the heavy pressure needed to penetrate hardened steel. These bits cut more aggressively and resist stress better than spiral-flute bits. A lower-priced alternative to solid carbide, they stay sharp when drilling abrasive material but won’t last as long.

Jobbers' Length—These bits have the balance of rigidity and length needed for most applications.

Cobalt Steel Drill Bits

Extended Length

Round Shank

Split

Tough and wear resistant, cobalt steel bits last at least twice as long as high-speed steel. They can also run up to 25% faster at higher temperatures without being damaged on hard materials, such as nickel.

Uncoated—Polished to eject chips, these are also known as bright finish bits.

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.

SDS-Plus Shank for Hammer and Rotary Drilling

SDS-Plus

Shank

The slotted shank fits SDS-Plus-drive rotary hammers, which rotate and hammer bits simultaneously to penetrate material. Also known as percussion or impact bits.

Carbide-Tipped Drill Bits

Round Shank

Standard

Performance similar to solid carbide but at a lower price point. Like carbide bits, these are stronger than cobalt and high-speed steel and maintain their sharp edges when drilling abrasive material. However, when drilling tough metals like iron and hardened steel, upgrade to carbide for longer life.

Milwaukee Cordless Drill/Drivers

Style D

A lithium ion (Li-Ion) battery powers these cordless drills, which means they weigh less and have a longer run-time than cordless drills that use nickel cadmium (NiCad) batteries. All have a variable speed motor—the further you depress the trigger, the faster the drill rotates.

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

Keyless Chuck—Drills with keyless chuck allow for fast bit changes and have an adjustable clutch that lets you adjust the torque.

Bluetooth—Drills with Bluetooth compatibility connect to the Milwaukee mobile app and let you track the location of the drills, customize their settings, view usage data, and receive alerts before they need repair.

Milwaukee Cordless Hammer Drills

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.
