Harvey Tool 73060-C3 Square End Mill 1/16 Inch 4 Flute

Product Description

The HARVEY TOOL 73060-C3 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 four flutes, it delivers clean, accurate cuts in tight geometries where rigidity and edge sharpness are critical. The AlTiN (Aluminum Titanium Nitride) coating improves heat resistance and extends tool life in ferrous and hardened materials. A 30-degree helix angle balances chip evacuation with cutting stability. This tool is sized for work in miniature features, slots, and fine detail passes on CNC milling machines.

This end mill is suited for precision machining applications in mold making, die work, medical component manufacturing, aerospace part production, and general CNC machining where small-diameter tooling is required. The 0.18 inch length of cut allows engagement in shallow-to-moderate depth slots and pockets. The 1/8 inch shank diameter fits standard ER collet systems and small-bore tool holders commonly found on vertical machining centers and high-speed spindles. Right-hand cut and right-hand flute orientation are standard for conventional CNC setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated heat resistance and extended tool life
• 4-flute configuration for improved surface finish and feed rate capacity
• 30-degree helix angle balances chip flow and cutting stability
• Centercutting design allows plunge milling operations
• Right-hand cut and right-hand flute - compatible with standard CNC spindle direction

Compatibility

Designed as a direct-fit replacement for 1/16 inch diameter square end mills in applications requiring a 1/8 inch shank. Compatible with ER11, ER16, and other collet systems accepting 1/8 inch shank tooling on CNC vertical machining centers and high-speed spindles.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the collet to the minimum clamping depth recommended by the tool holder manufacturer to prevent pullout under load. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
