Harvey Tool 886310-C6 Square End Mill 5/32 Inch 4 Flute

Product Description

The HARVEY TOOL 886310-C6 is a solid carbide square end mill designed for precision milling in demanding machining environments. It features a 5/32 inch (0.1562 inch) cutting diameter with a 5/8 inch length of cut and a 3/16 inch shank diameter, giving it a compact profile suited for tight-tolerance work. The 4-flute geometry with a 34-degree variable helix reduces chatter and harmonics during the cut. An AlTiN Nano finish improves heat resistance and surface hardness, extending tool life in ferrous and hard materials. Overall length is 3 inches and the tool weighs approximately 0.05 pounds. This is a centercutting, right-hand cut, right-hand flute configuration.

This end mill is suited for milling operations in precision machining shops, tool rooms, and production environments working with steel, stainless steel, hardened alloys, and similar materials. The reduced shank-to-cutting-diameter ratio makes it appropriate for profiling, slotting, and finishing passes in areas with restricted radial clearance. Machinists running CNC vertical mills or machining centers will find this geometry particularly effective for maintaining consistent chip evacuation in deep-wall or narrow-pocket applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN Nano finish provides elevated heat resistance and extended tool life
• 34-degree variable helix reduces chatter and improves surface finish
• Centercutting design allows plunge entry without pre-drilling
• Right-hand cut, right-hand flute — standard CNC spindle compatible
• 4-flute configuration balances chip clearance with cutting efficiency

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard CNC machining center tool holders accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the end mill. Use an appropriate collet or tool holder rated for the 3/16 inch shank diameter and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator after installation before beginning the cut cycle.
