Available in a Variety of Grades

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. Metal bonds help abrasives endure repeated wear without breaking down too easily. This hand file comes in a variety of grades: 125, 74, 40, and 20 microns. 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.

Overall, the 3M™ Flexible Diamond Hand File 6210J is an effective tool for cutting and accessing hard-to-reach areas. It is a must-have for any operator looking for a hand-held tool that combines sharp cutting action with ergonomic design.
