Harvey Tool 972316-C3 Square End Mill 1/4 in 4 Flute Altin

Product Description

The HARVEY TOOL 972316-C3 is a solid carbide square end mill designed for precision material removal in demanding machining applications. With a 1/4 inch mill diameter, 3/4 inch length of cut, and 4 inches overall length, this single-end tool delivers tight-tolerance profiling, slotting, and peripheral milling. The 30-degree right-hand helix geometry promotes efficient chip evacuation while reducing cutting forces. An AlTiN coating extends tool life by improving thermal resistance and hardness at the cutting edge. The 2-inch reach length makes this end mill well suited for deep-cavity and long-reach setups where standard-length tools cannot access the workpiece.

This end mill is built for machinists and CNC operators working in tool-and-die, aerospace, and precision job-shop environments. It is rated for use on steel, stainless steel, cast iron, aluminum and non-ferrous materials, and CFRP composites. The center-cutting geometry allows plunge entry, supporting ramp and helical interpolation strategies in addition to conventional profiling passes. Its compact 1/4 inch shank diameter fits standard ER and precision collet toolholders common in vertical machining centers and CNC mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• AlTiN coating improves heat resistance and extends tool life in dry and semi-dry cutting conditions
• 30-degree right-hand spiral flutes promote efficient chip flow and reduce built-up edge
• 2-inch reach length supports deep-cavity profiling and long-reach setups
• Center-cutting design allows plunge, ramp, and helical entry strategies
• Single-end configuration with 4-flute layout balances material removal rate and finish quality

Compatibility

Designed for use in CNC milling applications on steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and CFRP materials. Part of the Harvey Tool Miniature End Mills - Square - Long Reach, Standard Flute series. Fits 1/4 inch collet toolholders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and toolholder are clean and free of chips before seating the shank to full depth. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear on small-diameter carbide tools. Consult the machine manufacturer and applicable shop safety standards when establishing feeds, speeds, and depth-of-cut parameters.
