Harvey Tool 50310-C3 Square End Mill 5/32 in 4 Flute

Product Description

The HARVEY TOOL 50310-C3 is a solid carbide square end mill designed for precision milling in demanding machining environments. It features a 5/32-inch (0.1562-inch) cutting diameter, a 9/32-inch (0.281-inch) length of cut, and a 3/16-inch (0.1875-inch) shank diameter, with a 2-inch overall length. The four-flute, right-hand cut and right-hand flute geometry promotes efficient chip evacuation and smooth surface finishes. An AlTiN coating improves heat resistance and tool life during high-speed or dry cutting operations. Machinists and CNC operators install this end mill in vertical or horizontal machining centers for small-feature, tight-tolerance work.

This end mill suits applications in ferrous and non-ferrous materials where small-diameter, high-precision cutting is required. Its centercutting capability allows direct plunge entry as well as conventional peripheral and slot milling. The 30-degree helix angle balances cutting forces and surface finish quality across a range of materials. It is a single-end tool, meaning once the cutting end is worn, the tool is replaced rather than reindexed. Typical applications include die and mold work, prototype machining, and production runs requiring fine detail at small scales.

Key Features

• 5/32-inch cutting diameter with 9/32-inch length of cut for small-feature precision milling
• Solid carbide construction for rigidity and extended tool life versus high-speed steel alternatives
• AlTiN coating for improved heat resistance and performance in dry or high-speed cutting
• 4-flute, right-hand cut geometry with right-hand flute direction for efficient chip removal
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 30-degree helix angle balances cutting forces and promotes quality surface finish

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 3/16-inch collet or end mill holder setups on CNC machining centers and manual mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Secure the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Verify spindle runout with an indicator before cutting to protect the small-diameter tool from premature breakage. Always power down the spindle completely before changing or inspecting the end mill.
