Harvey Tool 995824 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 995824 is a solid carbide square end mill designed for precision milling operations in demanding machining environments. With a 3/8 inch diameter, a 1-1/8 inch length of cut, and 4 right-hand flutes at a 30-degree helix angle, this tool delivers clean, accurate cuts in hard and abrasive materials. The CVD diamond coating significantly extends tool life and reduces friction when cutting nonferrous metals, composites, graphite, and ceramics. Centercutting capability allows for plunge entry as well as conventional milling passes. This end mill is a single-end tool with a 3/8 inch shank diameter and 2-1/2 inch overall length.

This end mill is suited for job shops, production floors, and toolrooms working with abrasive or nonferrous workpiece materials. The CVD diamond coating makes it particularly effective when machining aluminum-silicon alloys, carbon fiber reinforced polymers, graphite electrodes, and other materials that rapidly wear uncoated carbide. It is sized for use in standard toolholders accepting 3/8 inch shank tooling and fits vertical machining centers, CNC mills, and manual knee mills equipped with appropriate collet or end mill holder systems.

Key Features

• Solid carbide substrate provides rigidity and wear resistance in abrasive materials
• CVD diamond coating extends tool life and lowers cutting friction in nonferrous and composite applications
• 4 right-hand flutes with 30-degree helix angle for efficient chip evacuation and smooth surface finish
• Centercutting design enables direct plunge entry without a pre-drilled pilot hole
• Single-end construction with 3/8 inch shank for compatibility with standard collets and end mill holders
• 2-1/2 inch overall length with 1-1/8 inch length of cut suits typical shallow-to-medium depth milling passes

Compatibility

Designed for use in CNC and manual milling machines with toolholding systems that accept a 3/8 inch shank diameter. Best suited for machining nonferrous metals, composites, graphite, and other abrasive or hard-to-machine materials where CVD diamond coating provides a performance advantage.

Installation Notes

This tool should be installed by a qualified machinist or toolroom technician familiar with carbide end mill handling. Ensure the machine spindle is fully stopped and locked out before loading or unloading tooling. Seat the shank fully into the collet or end mill holder and torque the retention hardware to the toolholder manufacturer specification. Avoid side-loading the cutting edge during tool changes, as solid carbide is brittle and prone to chipping if struck or dropped.
