Chuck 13 mm Size Key with adaptor

A chuck key with adaptor is a versatile tool used for tightening and loosening the chuck on power drills and other machinery with keyed chucks. The chuck key typically features a T-shaped handle with a square-shaped end that fits into the chuck's keyhole.

The adaptor, also known as a chuck keyless adapter or chuck keyless conversion kit, allows the chuck key to be used with a variety of different-sized chuck keyholes. This enables the chuck key to be compatible with multiple drills or machinery with different chuck sizes, offering convenience and flexibility.

The chuck key with adaptor is essential for securely fastening drill bits, sanding attachments, or other accessories into the chuck of the power tool. It provides a secure grip and ensures that the attachments are held firmly in place during operation, preventing slippage and ensuring safety.
