Harvey Tool 978410 Square End Mill 5/32 in 3 Flute Carbide

Product Description

The HARVEY TOOL 978410 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 5/32 inch (0.1562 inch) cutting diameter and a 15/64 inch (0.234 inch) length of cut, this end mill handles slotting, profiling, and finishing passes in a compact geometry. The 3-flute design balances chip evacuation with rigidity, making it effective in both ferrous and non-ferrous materials. At 3 inches overall length and a 3/16 inch shank diameter, it mounts in standard collet chucks and end mill holders on CNC machining centers and manual mills alike. The bright uncoated finish suits general-purpose use where coating compatibility with cutting fluid is a consideration.

This end mill is suited for light-to-medium material removal in precision machining environments, including tool rooms, job shops, and production floors. The 30-degree helix angle promotes smooth cutting action and efficient chip flow, which reduces heat buildup during extended cuts. Centercutting capability allows direct plunge entry without a pre-drilled pilot hole, giving machinists flexibility in pocketing and profiling operations. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 3-flute geometry balances chip clearance and cutting stability
• 30-degree helix angle promotes smooth cutting action and chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Bright uncoated finish compatible with a wide range of cutting fluids and materials
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use in standard 3/16 inch collet chucks and end mill holders on CNC machining centers, manual knee mills, and similar equipment where a right-hand spindle rotation is used.

Installation Notes

Install in a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the shank and collet bore for chips or damage before seating the tool. Confirm spindle direction is set to right-hand rotation before engaging the cut. Follow shop-standard speeds and feeds for solid carbide tooling in the material being machined.
