Product description
A chuck key, or chuck wrench, is a tool that is made for the purpose of tightening or loosening the jaws of a chuck.
A chuck is a type of clamp that is used to hold a cylinder object in place.
On a lathe, it holds the rotating piece.
Alternatively, it holds the rotating tool on a drill or mill.
Drill chuck keys tighten and loosen the jaws of a keyed drill chuck so drill bits can be installed or removed.
They have a specific post size, tooth angle, and tooth count to mate with a compatible chuck and prevent stripping of the chuck's gear teeth.
Standard Keyed chucks are designed to use a key to loosen or tighten the grip on a tool.
When slippage is an issue during heavy-duty operations, keyed chucks have the benefit of delivering additional torque to the bit.
They can rotate in either a clockwise or a counterclockwise direction.
