Harvey Tool 956905-C3 Square End Mill 0.1180 in 4 Flute

Product Description

The HARVEY TOOL 956905-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.1180-inch cutting diameter, 4-flute geometry, and a 30-degree helix angle, this tool delivers efficient chip evacuation and a smooth surface finish in both roughing and finishing passes. The AlTiN coating provides thermal resistance and extended tool life when cutting ferrous and hardened materials. It features a 0.125-inch shank diameter and an overall length of 1.5 inches, making it well-suited for tight-clearance work and small-part machining on CNC mills and machining centers.

This end mill is built for machinists and tool-and-die professionals working with small-diameter, close-tolerance features. The extended reach design, with a reach length of 0.625 inches and a length of cut of 0.354 inches, allows access to deeper pockets and stepped features without sacrificing rigidity. It is appropriate for use in job shops, production facilities, and prototype environments where consistent dimensional accuracy in small-scale milling is required. The right-hand cut and right-hand flute orientation are standard for conventional CNC vertical milling setups.

Key Features

• 0.1180-inch cutting diameter with 4-flute design for improved feed rates and finish quality
• AlTiN coating for high-heat resistance and extended tool life in ferrous and hardened materials
• 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Extended reach geometry with 0.625-inch reach length for deeper pocket access
• Centercutting capable, allowing plunge entry directly into the workpiece
• Solid carbide construction for rigidity and dimensional consistency at small diameters

Compatibility

Designed for use in CNC machining centers and vertical mills with 1/8-inch collet or toolholder systems. Suitable for small-diameter milling applications within the 0.3000 to 0.5000 inch length-of-cut range.

Installation Notes

Install in a collet or end mill holder rated for 0.125-inch shank diameters and verify runout before beginning a cut. Ensure the spindle and toolholder are clean and free of chips or debris before seating the tool. Follow machine manufacturer torque guidelines when tightening the collet nut. Small-diameter carbide end mills are brittle and susceptible to breakage from improper fixturing, excessive radial load, or interrupted cuts without appropriate feed and speed adjustments.
