Dorian Tool 73310123644 Standard Knurl Wheel 3/4 in 25 Tpi

Product Description

The DORIAN TOOL 73310123644 is a standard knurl wheel designed for use in knurling operations on metal lathes and similar turning equipment. This wheel features a right-hand diagonal tooth pattern with a 90-degree included tooth angle and a 25 TPI circular pitch, producing a medium-pitch knurl finish on workpieces. Manufactured from high speed steel with a bright finish, it delivers consistent pattern transfer across a range of metals. The 30-degree helix angle and Series A classification make it a straightforward selection for standard form-type knurling applications. Machinists and toolroom professionals install this wheel as part of a knurling tool holder assembly.

This knurl wheel is suited for form knurling operations on manual and CNC lathes in production and job-shop environments. The diagonal tooth pattern produces a right-hand diagonal texture commonly applied to handles, grip surfaces, and fastener heads requiring a defined knurl finish. At 3/4 inch diameter with a 3/8 inch face width and a 1/4 inch hole diameter, it fits standard Series A knurl tool holders used in light to medium turning work. It is appropriate for residential shop, commercial machine shop, and industrial production settings.
