Combining Sharp Cutting Action with Ergonomic Design

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 a good tool to have on hand when you're searching for effective cutting action and a hand-held tool that can help you access those hard-to-reach areas.
