Harvey Tool 871316 Square End Mill 1/4 in 4 Flute Carbide

Product Description

The HARVEY TOOL 871316 is a solid carbide square end mill designed for high-performance milling in abrasive and composite materials. With a 1/4 inch cutting diameter and a 1 inch length of cut, this single-end tool delivers precise, flat-bottomed profiles in demanding machining environments. The CVD diamond coating provides exceptional hardness and wear resistance, making it well-suited for cutting graphite, carbon fiber, fiberglass, ceramics, and other non-ferrous abrasive materials. Four right-hand flutes with a 30-degree helix angle contribute to efficient chip evacuation and surface finish quality. Licensed machinists and CNC operators use this tool in production and job-shop settings where tool life in abrasive materials is a priority.

This end mill is built for dry or near-dry machining of composites, reinforced plastics, graphite, and similar non-metallic abrasive materials. The CVD diamond coating is not intended for ferrous metals. It fits standard 1/4 inch collets and tool holders, making it easy to deploy on vertical machining centers, CNC routers, and similar platforms. It is a single-end, non-centercutting tool, meaning it is designed for peripheral and slot milling rather than plunge cutting.

Key Features

• CVD diamond coating for extreme wear resistance in abrasive and composite materials
• Solid carbide construction for rigidity and dimensional stability
• 4 right-hand flutes with 30-degree helix for efficient chip evacuation
• 1/4 inch shank matches standard collet and toolholder sizes
• Single-end, right-hand cutting direction
• Non-centercutting design suited for peripheral and slotting operations

Compatibility

Designed for use in standard 1/4 inch collet chucks and end mill holders on CNC machining centers and routers; intended for non-ferrous and abrasive materials such as graphite, carbon fiber, and fiberglass composites.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully in the collet or tool holder and torque the retention hardware per the toolholder manufacturer specifications. CVD diamond-coated tools should not be used on ferrous materials, as this will cause rapid coating degradation.
