Lock the bit into the chuck to prevent accidental disengagement.

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.

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.

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.

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.

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

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

A scaled-down version of standard changeable-shaft screwdrivers, these tools are shorter, slimmer, and easy to take with you. Remove and replace the shaft to use a different tip size.

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.

Set includes a handle and six shafts. Remove and replace the shaft to use a different size or drive style.

Choose a handle based on torque and change shafts to use a different size or drive style. Factory-set screwdrivers ensure you reach the same torque every time.

The extra-long shaft lets you access fasteners in deep recesses. To change tips, use a hex key to loosen the set screw.
