Combining Sharp Cutting Action with Ergonomic Design

3M™ Flexible Diamond Hand File 6210J is a hand-held tool that incorporates diamond material to help operators gain instant access to the workpiece. It is an ideal solution for parts that have hard-to-reach areas or edges that may be difficult to access.

3M™ Flexible Diamond Hand File 6210J includes all the desirable attributes of 3M Flexible Diamond products, such as sharp cutting action and responsive design, with the user-friendliness of a hand tool. The plastic handle is rigid yet lightweight, making it easy to use.

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. Metal bonds help abrasives endure repeated wear without breaking down too easily. Diamond, one of the toughest minerals, is long-lasting and cuts sharp. 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 for error when they're 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.
