Harvey Tool 15224-C4 Square End Mill 3/8 Inch 4 Flute

Product Description

The HARVEY TOOL 15224-C4 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 3/8-inch cutting diameter, a 1-inch length of cut, and a 30-degree helix angle, this tool delivers clean, accurate results across a range of materials. The amorphous diamond coating reduces friction and extends tool life by improving surface hardness and wear resistance. At 2.5 inches overall length with a 3/8-inch shank diameter and 4 flutes, this end mill is suited for moderate-depth slotting, profiling, and pocketing. Licensed machinists and CNC programmers will find it ready to run right-hand cut with right-hand flute geometry.

This end mill is used in job shop and production environments for milling ferrous and non-ferrous metals, plastics, and composites. The centercutting design allows direct plunge entry without a pre-drilled pilot hole, making it flexible for both roughing and finishing passes. A length-of-cut range of 1.0 to 1.25 inches accommodates typical workpiece depths in vertical machining center setups. It is a single-end tool, so all cutting life is concentrated in the one cutting end.

Key Features

• Solid carbide construction for rigidity and thermal resistance at high feed rates
• Amorphous diamond coating for improved wear resistance and reduced built-up edge
• 30-degree helix angle balances chip evacuation and cutting force across flute length
• Centercutting geometry supports direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute for standard CNC spindle operation
• 4 flutes for improved finish quality on profiling and finishing passes

Compatibility

Designed as an OEM-style solid carbide square end mill for use in CNC machining centers and manual mills with a 3/8-inch collet or end mill holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder, ensuring adequate engagement depth to prevent pullout under cutting load. Verify spindle runout is within acceptable tolerance before engaging the workpiece. Always follow machine manufacturer guidelines and applicable shop safety procedures when installing or changing cutting tools.
