Dorian Tool 73310128116 Standard Knurl Wheel 25 Tpi

Product Description

The DORIAN TOOL 73310128116 is a standard knurl wheel designed for form knurling operations on manual and CNC lathes. Made from cobalt with a TiN finish, this wheel produces a left-hand diagonal knurl pattern on workpiece surfaces. It measures 1 inch in diameter with a 3/8-inch face width and fits a 1/2-inch mandrel bore. The 25 TPI circular pitch and 30-degree helix angle work together to produce consistent, well-defined knurling on a variety of metals. With a 90-degree included tooth angle and medium pitch classification, this is a reliable production-grade wheel for machinists and tool room technicians.

This knurl wheel is suited for lathe work in machine shops, toolrooms, and production environments where a diagonal knurl pattern is specified. It is part of the SW4 series and is intended for use in standard knurling tool holders that accept 1/2-inch bore wheels. Left-hand diagonal orientation makes it compatible with right-hand diagonal wheels in bump or scissor-style knurling systems where a diamond pattern is not required. Typical applications include adding grip texture to handles, shafts, and thumb screws.

Key Features

• Cobalt construction with TiN finish for extended wheel life and wear resistance
• Left-hand diagonal tooth pattern for form knurling applications
• 25 TPI circular pitch, medium pitch classification
• 90-degree included tooth angle for crisp, defined knurl impression
• 30-degree helix angle for smooth cutting action
• SW4 series designation for compatibility with matching tool holders

Compatibility

Part of the DORIAN TOOL SW4 knurl wheel series. Designed for use in knurling tool holders that accept a 1/2-inch bore wheel with 1-inch outer diameter. Confirm tool holder bore and wheel series requirements before ordering.

Installation Notes

Installation is performed by a machinist or tool room technician. The wheel should be mounted on the appropriate mandrel or knurling tool holder, ensuring the bore fits cleanly without play. Secure the lathe spindle lock and verify all tooling is clamped before beginning a knurling pass. Do not exceed the tool holder or machine manufacturer's recommended feed and speed parameters for cobalt knurl wheels.
