Dorian Tool 73310120620 Cut Knurler 1 in Straight

Product Description

The DORIAN TOOL 73310120620 is a cut knurler designed for producing straight knurl patterns on cylindrical workpieces in a lathe or turning center. The tool body accepts a 1 inch wide knurling head with a 6-7/8 inch long shank, providing reach and rigidity for consistent pattern depth. Cut knurling applies a shearing action rather than displacement, making it well suited for harder materials and tightly toleranced parts where form knurling could introduce excessive radial pressure. Two knurl wheels are required for operation, and knurl wheels are included with this unit. Machinists and toolroom technicians working in production or job shop environments rely on this style of knurler for repeatable, clean pattern results.

This cut knurler is appropriate for use on manual engine lathes, CNC turning centers, and turret lathes where a straight knurl pattern is required. Typical applications include grip surfaces on hand tools, medical instrument handles, hydraulic fittings, and industrial fasteners. The straight pattern configuration produces linear ridges parallel to the workpiece axis, a common requirement in mechanical and industrial part production. Series M designation indicates the tooling series this holder belongs to within the DORIAN TOOL product line.

Key Features

• Cut knurling action reduces radial pressure on workpiece compared to form knurling
• 1 inch wide knurling head width for broad pattern coverage
• 6-7/8 inch long shank for extended reach and setup flexibility
• Straight knurl pattern included
• Two knurl wheels required - knurl wheels included
• Series M tooling designation for compatibility within the DORIAN TOOL modular system

Compatibility

Designed as an OEM-style cut knurler for use in Series M tooling setups on standard engine lathes and CNC turning centers that accept shank-style knurling holders.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the shank firmly in the tool post or turret before operation and confirm the knurl wheels are properly seated and locked. Power down and bring the spindle to a complete stop before changing knurl wheels or adjusting the holder position. Follow the machine manufacturer guidelines for feed rate and RPM when running cut knurling operations to avoid wheel slippage or uneven pattern depth.
