Manual Punch Grinder with 4 Accuracy Options, Surface Grinder Punch Grinding Tool Ø1.5-25mm Double Roller (0.008 mm)

The Manual Punch Grinder is a precision metalworking tool designed to be used with surface grinding machines for cylindrical punch grinding. Its double roller design automatically centers the workpiece, allowing machinists to achieve concentric grinding without complicated adjustments. The pressure arm rollers can rotate and move left or right to position the workpiece accurately before grinding. This punch grinder supports diameters from 1.5mm to 25mm and an extended grinding length of 5–35mm, making it suitable for grinding punches, tooling components, and precision metal parts. Built with a forged steel body and SUS440 hardened rollers, the tool provides excellent durability and stability even during heavy grinding operations. Available in four precision levels from 0.001mm to 0.008mm, it meets the needs of both standard machining and ultra-precision grinding applications.
