Harvey Tool 814862-C3 Square End Mill 1/16 in 3 Flute

Product Description

The HARVEY TOOL 814862-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 a 1/4 inch length of cut, this tool handles slotting, profiling, and contouring in tight geometries. The AlTiN coating provides thermal resistance and hardness, extending tool life when cutting ferrous and high-temp alloy materials. A 37-degree variable helix geometry reduces chatter and improves chip evacuation compared to fixed-helix designs. Machinists, toolroom operators, and CNC programmers working in aerospace, die-mold, and precision job shop environments will find this tool suited for fine-feature work.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter tooling is required. The 1/8 inch shank diameter allows it to fit standard collets and toolholders commonly found in vertical machining centers and high-speed spindles. It is a single-end, right-hand cut, right-hand flute tool with a 2-1/2 inch overall length. It is not center-cutting, so it is not intended for direct plunge operations. Best suited for side milling, slotting within its length-of-cut range, and finish passes on small features in hardened or difficult-to-machine materials.

Key Features

• AlTiN coating for high-temperature resistance and extended tool life in ferrous and exotic alloys
• 37-degree variable helix reduces vibration and chatter during cut
• 3-flute geometry balances chip clearance and rigidity at small diameters
• Solid carbide construction for stiffness and wear resistance in precision applications
• 1/8 inch shank fits standard ER collets and small-bore toolholders
• Not center-cutting — designed for peripheral milling and slotting, not plunge entry

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual mills accepting a 1/8 inch shank collet or toolholder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down the spindle and confirm zero RPM before installing or removing tooling. Use a calibrated torque wrench and proper collet nut when securing the shank to avoid runout. Confirm tool projection and length-of-cut engagement match the programmed operation before running — do not exceed the stated 0.25 inch length of cut in engagement depth.
