Knurling Tool Holder


SKU: 3004 Category:

Product Description

Sherline’s knurling system can add that “professional” look to your parts. Knurls are embossed into the surface of a part rather than cut. Straight knurls are often used at the end of a shaft that is to be pressed into another part. Straight or diamond knurl patterns are used to provide better grip on handwheels and thumbscrews.


The typical diamond knurl finish; straight knurls are also available.

The tool will handle diameters up to 1″ (25 mm) and consists of a right and left side that evenly tighten down on your part, while it is turned in the lathe, creating a knurled pattern. The holder is supplied with one set of spiral knurls that creates a diamond pattern.

Other size knurls for diamond or straight patterns are also available.

NOTE: The knurling tool was not designed for use with riser blocks.
