Bit Adapters

Use hex-shank bits (also known as insert bits) in powered tools.

Secure-Hold Bit Adapters

Lock your bit into the adapter to prevent accidental disengagement. These adapters hold hex-shank bits (also known as insert bits) in powered tools.

Screw-Holding Bit Adapters

A magnetic ring at the end of the adapter holds flat-head screws in place to ensure good contact between the bit and screw. Use these adapters to hold hex-shank bits (also known as insert bits) in powered tools.

Tight-Clearance Bit Adapters

The head is angled 90° to drive fasteners in tight spaces. Use these adapters to hold hex-shank bits (also known as insert bits) in powered tools.

Screw-Guiding Bit Adapters

Keep bits from slipping. Insert a bit into the adapter, place a screw on the end of the bit, and slide the adapter sleeve over the screw. The sleeve retracts as the screw is driven. These adapters hold hex-shank bits (also known as insert bits) in powered tools.

Flexible Bit Adapters

Bend these adapters up to 90° to access hard-to-reach fasteners. Use them to hold hex-shank bits (also known as insert bits) in powered tools.

Secure-Hold Bit Adapters for Ratchet Wrenches

Lock your bit into the adapter to prevent accidental disengagement. These adapters attach to square-drive tools.

Bit Adapters for Ratchet Wrenches

Attach these adapters to square-drive tools.

Bit Adapters for Impact Drivers

These adapters are designed to withstand the high torque of impact drivers. They hold hex-shank bits (also known as insert bits).

Bit Adapters for Impact Wrenches

Designed to withstand high torque and force, these adapters fit the square drive on impact wrenches. Use with hex-shank bits (also known as insert bits).

Bit Adapters for Bit Screwdrivers

Use a 4 mm bit in a bit driver that's designed for 1/4" bits.

Bit Adapters for Rotary Hammers

Insert these adapters into your SDS-drive rotary hammer to use it with hex-shank bits (also known as insert bits).

Torque-Measuring Bit Adapters

Eliminate the need for multiple bulky tools with these bit adapters. At less than 3 inches long, these compact adapters convert ¼” bit screwdriver handles and ¼” bits into torque screwdrivers so you can fasten to a specific torque.

Bit Organizers

Bit Organizing Cases

Fit these small cases comfortably in your pocket.

Bit Organizing Trays

Store a variety of sizes and styles of bits and adapters in one compact tray.

Bit Organizing Caddies

Keep these caddies in your tool drawer or take them with you.

Magnetic Bit Organizing Caddies

Mount the magnetic base to walls, cabinets, and other steel surfaces.

Bit Screwdrivers

Secure-Hold Bit Screwdrivers

Lock the bit into the chuck to prevent accidental disengagement.

Bit Screwdrivers

Insert a bit into the shaft and a magnet holds it in place.

Tight-Clearance Bit Screwdrivers

Operate these tools like a standard bit driver and access hard-reach fasteners with the offset head. Insert a bit and a magnet holds it in place.

Nonmagnetic Bit Screwdrivers

Bits are held in place with a retaining ring or set screw rather than a magnet, so the tool won't attract loose metal parts and shavings.

Tight-Clearance Ratcheting Bit Screwdrivers

A ratchet mechanism allows you to drive fasteners when there's little space to move the handle.

Fast-Driving Ratcheting Bit Screwdrivers

Drive screws four times faster than ratcheting alone. Grip the speed housing at the base of the shaft with one hand while turning the handle with the other. A magnet at the end of the shaft holds bits in place.

Ratcheting Bit Screwdrivers

A ratchet mechanism turns fasteners more quickly than a standard bit driver. Insert a bit into the shaft and a magnet holds it in place.

Static-Control Bit Screwdrivers

Also known as ESD-safe bit screwdrivers, the handle drains static away from your application, preventing buildup from electrostatic discharge (ESD) that can damage sensitive equipment.

Electrical-Insulating Bit Screwdrivers

An insulated handle and shaft protect against shock from accidental contact with live electrical circuits. These tools are tested to 1,000 volts to meet EN 60900 and IEC 60900.

Flexible-Shaft Bit Screwdrivers

Bend the shaft around obstructions to reach fasteners that standard and offset screwdrivers can’t.

Reversible-Bit Screwdriver/Nutdrivers

Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

Stubby Reversible-Bit Screwdriver/Nutdrivers

When working in tight spaces, these short drivers fit where others can't. Bits have a different tip at each end and snap into the shaft, which is also a nutdriver.

Precise-Control Bit Screwdrivers

Use these tools with 1/4" hex shank screwdriver bits. The rotating end cap on the handle allows you to apply constant pressure with your palm while turning the body of the driver with your fingertips.

Drill Bit Organizers

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 Drawer Cabinets

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

Magnetic Pouches for Drills

These pouches fit onto most hand-held power drills and impact drivers. They have a magnetic panel on the front that can hold bits and fasteners.

Drill Bit Pouches

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

Reduced-Shank Drill Bit Stands

Each hole is sized to hold the 1/2" shank of a reduced-shank drill bit and marked with a bit size.

Drill Bit Stands

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

Drill Bit Cases

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

Drill Bit Extensions

Quick-Change Extensions for Hex-Shank Drill Bits

A quick-change mechanism allows fast bit changes.

Extensions for Hex-Shank Drill Bits

Tighten the set screws to secure the drill bit in the extension.

Adjustable-Length Quick-Change
Extensions for Hex-Shank Drill Bits

Adjust these extensions to the desired length. They have a quick-change mechanism for fast bit changes.

Extensions for Round-Shank Drill Bits

Attach to the shank of a drill bit to extend its reach.

Extensions for SDS-Plus-Shank Drill Bits

SDS-Plus shanks have two deep slots and two shallow slots for use with SDS-Plus-drive rotary hammers. These extensions have a quick-change mechanism for fast bit changes.

Changeable-Size SDS-Max-Shank Masonry Core Drill Bits for Rotary Hammers

Changeable-Size SDS-Max-Shank Masonry
Core Drill Bits for Rotary Hammers

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.

Machine Tool Holding

Small-Hole Drill Chuck Adapters

Drill extremely small holes with a drill press using these adapters. The shank fits into a collet or adjustable drill chuck, and the other end securely holds a wire gauge drill bit.

Drill Chuck Adapters for SDS-Drive Rotary Hammers

One end attaches to your SDS-drive rotary hammer, and the other end attaches to a drill chuck so you can perform regular drilling and driving operations with round- and hex-shank drill bits.
