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.

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.

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.

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

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

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

When you don't have exact alignment between the fastener and the bit, the ball end allows angled entry to turn screws in hard-to-reach areas. A retaining ring grips inside the recess to hold screws in place.

The toughest bits available, these withstand the shock and twisting force of impact drivers.

The slightly tapered tip wedges into the screw recess for a secure hold. These are also known as Torx-Align bits.

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

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.

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.

The bit holder ratchets so you can drive fasteners when there's little space to move the handle. A magnet or retaining ring secures the bit in the holder.

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.

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