Harvey Tool 935808-C6 Square End Mill 0.125in 4 Flute Carbide

Product Description

The HARVEY TOOL 935808-C6 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous metals, hardened steels, and high-temperature alloys. With a 0.125 inch cutting diameter and a 4-flute geometry featuring a variable helix design, this end mill delivers improved chip evacuation and reduced chatter across a wide range of cutting conditions. The AlTiN coating increases surface hardness and thermal resistance, extending tool life in demanding applications. At 2.5 inches overall length with a 1.25 inch reach, it is well-suited for deep-pocket and extended-reach milling operations requiring a small-diameter tool.

This end mill is used in CNC machining centers and manual mills in both shop and production environments. The 0.187 inch length of cut and center-cutting capability allow it to plunge directly into workpieces and handle slotting, profiling, and contouring operations. The right-hand cut and right-hand flute configuration is standard for conventional CNC spindle setups. Machinists working with tight tolerances in aerospace, mold and die, and medical component applications will find this geometry appropriate for finishing and light roughing passes at small diameters.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating for elevated thermal resistance and extended tool life
• Variable helix geometry reduces chatter and improves surface finish
• Center-cutting design allows direct plunge entry into workpieces
• Extended reach of 1.25 inches accommodates deep-pocket milling with a 0.125 inch diameter tool
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard production end mill for CNC machining centers and manual mills accepting a 0.125 inch shank diameter collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down or in an e-stop state before changing tooling. Seat the shank fully into the collet or tool holder to the minimum recommended engagement depth before tightening. Verify runout with a dial indicator after installation, especially critical at this diameter, to prevent premature tool breakage.
