Hex Bits

Hex Shank

Hex Shank for Power Tools

These multipurpose bits are strong and durable.

Hex shank bits (also known as insert bits) are used in hand drivers or with a bit adapter in power tools.

Hex shank bits for power tools have a groove in the shank and fit directly into power tools without an adapter. They offer more reach for recessed holes and less wobble compared to a hex shank bit used with an adapter.

Ball-End Driver Shafts

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.
