Socket Adapters and Extensions

Hex Shank to Power Socket Square
Drive and Impact Square Drive Adapters

Use sockets with tools that accept hex shanks, such as impact drivers and power drills.

Hex Shank to Square Drive Adapters

Turn sockets with a bit screwdriver.

Angled Hex Shank to Square Drive Adapters

The angled shape lets you use your bit driver like a wrench.

Drivers, Keys, and Bits

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.

Bit Adapters

Use 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.

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.

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.

Bit Adapters for Bit Screwdrivers

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

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).

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 Rotary Hammers

Insert these adapters into your SDS-drive rotary hammer to use it with 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 Assortments

Assortments contain bits with multiple drive styles.

High-Torque Bit Assortments

Less likely to crack or shatter under high torque than standard bits, these are often used with power tools to install machine screws.

Precise-Control Bit Assortments

The knurled shank on these bits allows finger tightening. They can also be used with the included screwdriver.

Tight-Clearance Ratcheting Bit Screwdrivers

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

Machine Tool Holding

Morse Taper Arbors with Drill Chuck

These arbors with chuck allow drills with a Morse taper spindle to accept standard drill bits.

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.

Hex-Shank Keyed Drill Chucks for
Power Screwdrivers and Impact Drivers

Convert a power screwdriver or impact driver into a versatile drill. Also known as adapt-a-drive, these chucks have a 1/4" hex shank that fits the hex drive in most power screwdrivers and impact drivers.

Hex-Shank Keyless Drill Chucks for
Power Screwdrivers and Impact Drivers

Convert a power screwdriver or impact driver into a versatile drill.

Drill Bit Shank Adapters for Power
Screwdrivers and Impact Drivers

For use in power screwdrivers and impact drivers that accept a 1/4" hex shank, each adapter holds a variety of round-shank drill bit sizes for quick tool changes.

Drilling

Chuck and Adapter for Jancy Magnetic-Base Drills

These chucks and adapters will allow your Jancy magnetic-base drill to accept standard drill bits.

General Purpose Right-Angle Drilling Attachments
