Diamond rolling knife: using natural industrial grade diamonds as the cutting head, after professional welding and grinding, the front end diamond is made into a hemispherical shape, and the high hardness metal surface is mirror rolled

Rolleable shafts, large inner holes, end faces, etc. with a hardness of HRC40-65 degrees.

Mainly targeting the outer diameter and inner hole processing of quenched workpieces

Attention to use: When using, the lubricating oil should be sufficient, and the workpiece must be rotated first before the diamond can come into contact for processing. Minimize jumping as much as possible when clamping workpieces.
