Harvey Tool 997712 Square End Mill 3/16in 4 Flute Cvd Diamond

Product Description

The HARVEY TOOL 997712 is a solid carbide square end mill designed for precision milling operations requiring exceptional hardness and wear resistance. With a 3/16 inch cutting diameter and a 9/16 inch length of cut, this single-end tool is built for finishing and profiling passes in abrasive and hard materials. The CVD diamond coating provides extreme surface hardness, making it well suited for machining graphite, carbon fiber, ceramics, green carbide, and other highly abrasive nonferrous materials. Four flutes with a compression flute geometry and a right-hand cutting and flute direction deliver clean, controlled chip evacuation. Licensed machinists and tooling technicians working in precision shops, aerospace, and composites fabrication are the primary installers of this tool.

This end mill is intended for use in CNC machining centers handling abrasive nonferrous materials where standard coatings fail prematurely. The 3/16 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting. The 2 inch overall length keeps the tool compact and rigid, minimizing deflection in tight-tolerance applications. It is a center-cutting tool, allowing plunge entry where the operation requires it. Extended reach is not a feature of this configuration.

Key Features

• CVD diamond coating for maximum wear resistance in abrasive nonferrous and composite materials
• Compression flute geometry promotes clean cuts and reduces delamination in layered materials
• 4-flute design balances chip clearance with surface finish quality
• Center-cutting capable for direct plunge entry
• Solid carbide construction provides rigidity and dimensional stability
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers accepting 3/16 inch shank end mills in collet chucks or end mill holders.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before tool changes. Seat the shank fully into the holder and torque the collet or set screw to the machine manufacturer specification. Verify runout with a dial indicator before beginning the cut, as even minor runout accelerates CVD coating wear in abrasive materials.
