3M super abrasive plated mandrels

3M™ Plated Mandrels

Diamond or CBN abrasive grains electroplated on quality steel mandrels. Shanks of hardened ground steel for assured concentricity, no truing required. Used for ID, jig or contour grinding. For best results, choose a mandrel sized at 70-80% of the hole diameter. Coolant is optional, but enhances performance; should be oil-based for CBN mandrels.
