The diamond mineral on 3M™ Flexible Diamond Hand File 6210J is securely anchored to a plastic file with a metal bond. Diamond is one of the toughest minerals, making it long-lasting and sharp.

Operators can choose the right grade for their unique application. The hand files themselves are color-coded to help operators keep track and reduce the risk of error when using multiple files in a sequence.
