Harvey Tool 875462-C6 Square End Mill 1/16 in 4 Flute Altin

Product Description

The HARVEY TOOL 875462-C6 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 1/16 inch (0.0625 inch) cutting diameter and 4 flutes arranged in a variable helix configuration, this end mill delivers reduced chatter and improved chip evacuation during high-speed cutting operations. The AlTiN coating provides elevated heat resistance and extended tool life when machining hardened steels, stainless alloys, and other difficult-to-cut materials. A 0.186 inch length of cut and 1-1/2 inch overall length make this tool well suited for finishing passes and close-tolerance slot work where rigidity and runout control are critical.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter, tight-tolerance work is required. Typical applications include die and mold work, small part profiling, slotting, and finishing operations in hardened ferrous and non-ferrous materials. The right-hand cut and right-hand flute direction are standard for conventional CNC setups. The 1/8 inch shank diameter is compatible with standard collet systems used in both vertical and horizontal milling configurations. Machinists and tooling specialists in production shops and job shops are the primary users of this tool.

Key Features

• 1/16 inch cutting diameter for fine detail and small-feature milling
• 4-flute variable helix geometry reduces harmonics and chatter at high feed rates
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• Solid carbide construction provides stiffness and dimensional stability in tight-tolerance applications
• Right-hand cut and right-hand flute direction for standard CNC compatibility
• Single-end configuration; not centercutting — plunge milling is not recommended

Compatibility

Designed as an OEM-style solid carbide square end mill for use with standard 1/8 inch collet systems in CNC machining centers and precision manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and locked out before changing or seating tooling. Secure the shank in a clean, properly sized collet or end mill holder to the appropriate pull-out force per the holder manufacturer's specifications — no specific torque value is provided here. Because this tool is not centercutting, avoid direct axial plunge entry into solid material; use ramping or helical entry paths instead.
