Harvey Tool 920624 Square End Mill 3/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 920624 is a solid carbide square end mill designed for precision milling operations in metal, composites, and similar materials. With a 3/8 inch cutting diameter and a 9/16 inch length of cut, it handles slotting, profiling, and peripheral milling in tight tolerances. The 4-flute geometry with a 30-degree helix angle supports efficient chip evacuation and a smooth surface finish. The reduced 5/16 inch shank allows access to applications requiring a smaller tool shank relative to cutter diameter. This is a single-end, right-hand cutting, right-hand flute tool with a bright uncoated finish, making it easy to inspect for wear. It is sized and built for use by machinists and CNC operators in job shop and production environments.

This end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 3/8 inch diameter cutter is required. The 6 inch overall length provides extended reach for deeper setups or work-holding situations that require additional clearance between the spindle and the workpiece. The centercutting capability allows for plunge cuts directly into the material without a pre-drilled entry point. Typical applications include profiling, contouring, slotting, and pocket milling in precision machining environments.

Key Features

• 3/8 inch cutting diameter with a 9/16 inch length of cut for accurate material removal
• 4-flute design with a 30-degree helix angle for efficient chip flow and surface finish quality
• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• Centercutting geometry enables direct plunge entry without a pilot hole
• Reduced shank diameter of 5/16 inch allows use in setups requiring shank clearance
• 6 inch overall length provides extended reach for deep or obstructed workpiece setups
• Bright uncoated finish for straightforward visual wear inspection

Compatibility

Designed as a standard square end mill for use in CNC machining centers and manual mills equipped with collets or end mill holders accepting a 5/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder rated for the 5/16 inch shank and torque the retention hardware according to the machine and holder manufacturer specifications. Confirm runout with a dial indicator after clamping before beginning the cut.
