Harvey Tool 906293 Corner Radius End Mill 3/32 in 4 Flute

Product Description

The HARVEY TOOL 906293 is a solid carbide corner radius end mill designed for high-precision material removal in non-ferrous materials and graphite. With a 3/32 inch (0.0930 inch) milling diameter and a 0.0300 inch corner radius, this single-end, center-cutting tool produces accurate edge geometry on demanding workpiece materials. The CVD diamond coating delivers exceptional hardness and wear resistance, making it well suited for abrasive materials that would rapidly degrade uncoated carbide tooling. A 4-flute, right-hand spiral configuration with a 30-degree helix angle supports both roughing and finishing passes in a single tool setup.

This end mill is intended for use in CNC machining centers handling composites, graphite, and other non-ferrous materials where surface finish and edge integrity are critical. The straight cylindrical shank mounts in high-precision toolholders, which are recommended to maximize runout control and tool life. Typical applications include mold and die work, electrode machining in graphite, and precision part finishing in aerospace or electronics manufacturing environments. Installation and operation are performed by machinists and CNC programmers working in precision machining shops.

Key Features

• CVD diamond coating for extended tool life in abrasive non-ferrous and graphite applications
• 0.0300 inch corner radius with tolerance of +0.0010 to -0.0010 inches for controlled edge geometry
• 4-flute, right-hand spiral design supports roughing and finishing in a single pass
• Center-cutting geometry allows direct plunge entry into workpiece material
• 30-degree helix angle promotes chip evacuation and reduces cutting forces
• Straight cylindrical shank compatible with high-precision toolholders for minimal runout

Compatibility

Designed for use with high-precision toolholders. Intended for machining non-ferrous materials, composites, and graphite. Not recommended for ferrous metals.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before tool changes. Mount the straight cylindrical shank in a high-precision collet or toolholder and verify runout before cutting. Use dry cutting or compressed air for chip evacuation when machining graphite; avoid flood coolant on CVD diamond-coated tools unless confirmed compatible with the coating.
