Harvey Tool 993712-C4 Square End Mill 3/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 993712-C4 is a solid carbide square end mill designed for precision material removal in demanding machining applications. With a 3/16-inch cutting diameter and a 9/16-inch length of cut, this tool delivers consistent, accurate results in tight-tolerance work. The 4-flute geometry and right-hand helix promote efficient chip evacuation while maintaining surface finish quality. An amorphous diamond coating extends tool life and reduces friction, making this end mill well-suited for machining abrasive or non-ferrous materials. The single-end configuration and 2-inch overall length make it a practical fit for standard toolholders used in CNC milling operations.

This end mill is intended for professional machinists and toolroom technicians working with CNC mills and machining centers. Its centercutting capability allows for direct plunge entry, expanding its utility in slot milling, profiling, and pocketing operations. The compression flute design and right-hand cutting direction are suited to applications requiring clean entry and exit cuts. It is particularly effective when machining graphite, composites, and other abrasive non-metallic materials where the amorphous diamond coating provides a meaningful performance advantage over uncoated or TiN-coated tooling.

Key Features

• Amorphous diamond coating reduces wear and extends tool life in abrasive material applications
• 4-flute, right-hand helix geometry for efficient chip flow and improved surface finish
• Centercutting design enables direct plunge milling without a pre-drilled pilot hole
• Compression flute type supports clean cuts in both entry and exit passes
• 3/16-inch shank diameter matches cutting diameter for direct straight-shank toolholder compatibility
• Solid carbide construction provides rigidity and resistance to deflection at small diameters

Compatibility

Designed as an OEM-style replacement and standard solid carbide square end mill for use in CNC machining centers and manual mills accepting a 3/16-inch straight shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank in a collet or end mill holder to the appropriate holding depth, and verify runout with a dial indicator before beginning a cut. Follow all applicable shop safety procedures and machine manufacturer guidelines when setting speeds and feeds.
