Harvey Tool 72199-C4 Square End Mill 1/4 in 2 Flute Carbide

Product Description

The HARVEY TOOL 72199-C4 is a 2-flute, solid carbide square end mill designed for precision milling operations in demanding shop environments. It carries a 1/4 inch cutting diameter and a 3/4 inch length of cut, with an amorphous diamond coating applied to extend tool life and reduce friction in abrasive materials. The 30-degree helix angle promotes smooth chip evacuation and stable cutting action. At 2.5 inches overall length with a 1/4 inch shank diameter, this is a single-end tool sized for close-tolerance work in CNC machining centers and manual mills. Machinists, tool-and-die professionals, and production shops install this tool for finishing and slotting passes where edge integrity matters.

This end mill is suited for milling composite materials, graphite, ceramics, carbon fiber, and other abrasive non-metallic workpiece materials where the amorphous diamond coating provides significant wear resistance compared to uncoated or TiAlN-coated carbide. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle setups. Its centercutting geometry allows plunge entry, giving operators flexibility in toolpath programming without requiring a pre-drilled pilot hole.

Key Features

• 1/4 inch cutting diameter with 3/4 inch length of cut for close-tolerance slotting and profiling
• Solid carbide construction for rigidity and dimensional stability under load
• Amorphous diamond coating for extended tool life in abrasive and composite materials
• 30-degree right-hand helix promotes efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry without a pilot hole
• Single-end, 2-flute configuration optimized for chip clearance in softer or abrasive non-metallics

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 1/4 inch straight shank toolholder, collet, or end mill adapter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully within the collet or toolholder to the manufacturer-specified engagement depth before tightening. Confirm spindle speed and feed rate settings are appropriate for the workpiece material and coating type before initiating a cut. Inspect the cutting edges for chips or wear before each use, as carbide tooling can fracture without visible warning if run on a damaged edge.
