Harvey Tool 962731 Square End Mill 1/32 in 4 Flute

Product Description

The HARVEY TOOL 962731 is a solid carbide square end mill designed for precision milling of hardened and abrasive materials. With a 1/32 inch (0.0310 inch) cutting diameter and a CVD diamond coating, this tool delivers exceptional hardness and wear resistance in demanding machining applications. The 4-flute, right-hand cutting geometry with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finishes. At 1-1/2 inches overall length and a 3/64 inch length of cut, this end mill is engineered for close-tolerance work where control and rigidity are critical. It is installed and operated by machinists and CNC tool operators.

This end mill is suited for milling graphite, composites, ceramics, and other highly abrasive non-ferrous materials where standard carbide tooling experiences rapid wear. The 1/8 inch shank diameter makes it compatible with standard collet systems used on CNC machining centers and high-speed spindles. Its centercutting capability allows plunge entry, expanding its utility in slotting and pocket milling operations. Single-end construction means the tool is replaced rather than indexed when the cutting edge is spent.

Key Features

• CVD diamond coating for superior wear resistance on abrasive and composite materials
• 4-flute, right-hand spiral geometry with 30-degree helix for efficient chip flow
• Centercutting design allows direct plunge entry into workpiece
• Solid carbide construction provides rigidity and dimensional stability at micro diameters
• 1/8 inch shank diameter fits standard ER collet and precision chuck systems
• Single-end configuration — replace when edge is worn, no indexing required

Compatibility

Designed for use with CNC machining centers and high-speed spindle setups equipped with 1/8 inch collet or precision chuck toolholding systems capable of holding micro-diameter solid carbide end mills.

Installation Notes

Installation and tool changes should be performed by qualified machinists following shop safety procedures. Power down and lock out the spindle before changing tooling. Seat the shank fully and evenly in the collet to the recommended engagement depth to prevent runout and tool pull-out during cutting. Avoid overtightening collet nuts, which can damage micro-diameter shanks; follow toolholder manufacturer torque guidelines.
