Harvey Tool 14620-C4 Square End Mill 5/16 in 2 Flute Carbide

Product Description

The HARVEY TOOL 14620-C4 is a 2-flute, solid carbide square end mill designed for precision material removal in CNC machining and manual milling applications. It features a 5/16-inch cutter diameter, a 5/8-inch length of cut, and a 2-1/2-inch overall length. The tool carries an amorphous diamond coating, which significantly increases surface hardness and reduces friction, making it well suited for cutting abrasive non-metallic materials such as graphite, carbon fiber, fiberglass, and composites. The 0-degree helix and non-centercutting geometry reflect a design optimized for side milling and slotting in these demanding materials.

This end mill is intended for use in production and job-shop machining environments where abrasive composite or non-ferrous materials are regularly encountered. The 5/16-inch shank diameter allows direct collet chuck mounting in standard toolholding systems. Right-hand cutting direction makes it compatible with conventional CNC vertical and horizontal machining centers. It is a single-end tool sold individually and is most commonly installed by machinists and CNC programmers working with advanced materials that accelerate tool wear on uncoated carbide.

Key Features

• Amorphous diamond coating extends tool life in abrasive composite, graphite, and fiberglass applications
• Solid carbide substrate provides rigidity and resistance to deflection at small diameters
• 2-flute geometry promotes chip evacuation during slotting and profiling
• 0-degree helix angle reduces axial cutting forces, beneficial in thin or brittle workpiece materials
• Right-hand cutting direction, compatible with standard CNC spindle rotation
• Non-centercutting design — suited for side milling and peripheral cuts, not plunge entry

Compatibility

Designed for use in standard collet-style toolholding systems accepting a 5/16-inch shank diameter. Best suited for CNC machining centers and manual mills cutting graphite, carbon fiber, fiberglass, and similar abrasive non-metallic materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. The machine spindle must be fully stopped and power locked out before changing tooling. Seat the shank fully into a clean, matched collet or toolholder and torque the retention system per the toolholder manufacturer specification. This tool is non-centercutting — do not program direct plunge moves; use ramping or helical entry strategies where a full-depth entry is required.
