F E A T U R E

The resilient resinoid bond helps absorb grinding vibration and improves contact with the workpiece, producing a fine and uniform surface finish. It is ideal for finish grinding of internal bores and jigs made of high-speed steel or hardened alloy steel, especially when surface quality is the priority.

◎  Key advantage: Fine surface finish and smooth grinding contact
◎  Main use: Precision finishing of internal bores and jigs
◎  Customization: Other grit sizes and specifications available on request
