Harvey Tool 997112-C3 Ball End Mill 4 Flute Solid Carbide

Product Description

The HARVEY TOOL 997112-C3 is a single-end ball end mill engineered for precision milling in ferrous and hard materials. Built from solid carbide with an AlTiN coating, it runs at high speeds while resisting heat and wear. The 0.1875-inch cutting diameter pairs with a 45-degree helix angle and 4-flute right-hand geometry to deliver clean material removal and smooth surface finishes. With a 0.16-inch length of cut and a 3-inch overall length, this tool is designed for controlled, accurate passes in confined features and contoured surfaces. It is used by machinists and tool-and-die professionals in CNC milling applications.

This ball end mill is suited for finish and semi-finish milling of 3D profiles, slots, pockets, and complex contoured surfaces. The reduced neck diameter of 0.117 inches and 1.0-inch neck length allow access to deeper features while limiting tool deflection. The 3/16-inch shank diameter fits standard collet chucks and end mill holders on CNC machining centers and manual knee mills. Applications include mold and die work, aerospace components, and precision part production where tight tolerances and surface quality are required.

Key Features

• Solid carbide construction for rigidity and long tool life in hard and abrasive materials
• AlTiN coating provides high-temperature resistance and reduced friction during dry or minimal-lubrication cutting
• 45-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• 4-flute right-hand geometry for efficient material removal and improved surface finish
• Reduced neck diameter (0.117 inches) enables reach into deeper pockets and contoured features
• Single-end design with 270-degree wrap angle for ball-nose profiling and 3D contouring

Compatibility

Designed for use in standard 3/16-inch collet chucks and end mill holders on CNC machining centers and manual milling machines capable of accepting solid carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the 3/16-inch shank fully into the collet or holder and torque the retaining nut to the tool holder specification. Verify runout with a dial indicator before beginning a cut, as excessive runout will accelerate wear and reduce surface finish quality on carbide end mills of this diameter.
