Dorian Tool 73310128140 Beveled Face Knurl Wheel 1 in 20 Tpi

Product Description

The DORIAN TOOL 73310128140 is a beveled face knurl wheel designed for form knurling operations on CNC lathes and manual turning machines. Built from high speed steel with a titanium nitride (TiN) finish, this wheel produces a left-hand diagonal knurl pattern at 20 TPI using a circular pitch system. The 90-degree included tooth angle and 30-degree helix angle deliver clean, consistent tracking in medium-pitch applications. At 0.05 pounds, this is a precision replacement wheel sized for the SW4 series knurling tool holder. Machinists and tool room professionals specify this wheel for high-volume turning operations where surface texture accuracy is required.

This knurl wheel fits residential and commercial machine shop environments wherever a Series SW4 knurling head is in use. It is suited for turning operations on steel, aluminum, and similar machinable materials where a diagonal left-hand pattern is specified by drawing or part requirement. The 1-inch diameter and 3/8-inch overall width make it compatible with standard SW4 tool holder configurations. It is sold individually and is a direct form-type replacement wheel, meaning no secondary cutting or chasing is required to achieve the finished knurl profile.

Key Features

• Left-hand diagonal tooth pattern for consistent single-wheel tracking
• 90-degree included tooth angle with 30-degree helix for clean knurl formation
• High speed steel construction with TiN coating for extended wheel life
• Circular pitch system at 20 TPI (1.27 mm pitch) for medium-pitch applications
• 54 teeth across a 1-inch diameter for uniform surface texture
• Series SW4 designation for direct fitment into compatible DORIAN TOOL holders

Compatibility

Designed as a replacement knurl wheel for Series SW4 knurling tool holders. Fits holders accepting a 1-inch diameter wheel with a 1/2-inch hole diameter and 3/8-inch overall width.

Installation Notes

Installation is performed by a qualified machinist during tooling setup on a lathe or turning center. Power down and lock out the spindle before removing or installing knurl wheels. Ensure the wheel seats fully and rotates freely on the holder pin before beginning a knurling pass. Follow the tool holder manufacturer's torque and clamping guidance for the SW4 series when securing the wheel assembly.
