Value Collection 42000207 Standard Knurl Wheel 25 Tpi

Product Description

The VALUE COLLECTION 42000207 is a standard cut knurl wheel designed for use on manual and CNC lathes to produce a left-hand diagonal knurl pattern on workpiece surfaces. Manufactured from powdered metal high speed steel with a bright finish, this wheel measures 11/32 inches (0.3437 inches) in diameter and operates on the circular pitch system at 25 TPI (1.00 mm pitch). The 30-degree included tooth angle and 30-degree helix angle work together to cut a clean, consistent diagonal pattern. Machinists and tool and die technicians install this wheel in a knurling tool holder for decorative or functional grip applications.

This knurl wheel is suited for general-purpose knurling operations in machine shop environments, including production turning, toolmaking, and repair work. The left-hand diagonal tooth pattern makes it appropriate for use as a single-wheel application or as part of a matched pair to produce a diamond pattern when combined with a right-hand diagonal wheel. Its compact diameter suits smaller knurling tool holders used on engine lathes and turret lathes.

Key Features

• Left-hand diagonal tooth pattern for single-wheel or paired diamond-knurl setups
• Cut-type form for precise, well-defined knurl impressions
• Powdered metal high speed steel construction for wear resistance
• Bright finish on all tooth surfaces
• Circular pitch system at 25 TPI (1.00 mm pitch) for consistent spacing
• 30-degree included tooth angle and 30-degree helix angle

Compatibility

Designed as an OEM-style replacement or spare knurl wheel for standard knurling tool holders that accept 11/32 inch diameter cut-type wheels on manual or CNC lathes.

Installation Notes

Installation is performed by a machinist or tool and die technician. Power down and lock out the lathe before mounting or removing the knurl wheel from the tool holder. Ensure the wheel spins freely on its pin or axle without lateral play before engaging the workpiece. Follow shop safety procedures and machine manufacturer guidelines when setting knurling tool pressure and feed rate.
