Harvey Tool 836378-C3 Square End Mill 5/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 836378-C3 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 5/64 inch (0.078 inch) cutting diameter and a 15/64 inch (0.234 inch) length of cut, this tool handles slotting, profiling, and finishing passes in tight geometries. The AlTiN coating increases surface hardness and heat resistance, extending tool life in harder workpiece materials. Three right-hand flutes with a 30-degree helix provide a balance of chip evacuation and finish quality. This end mill is center-cutting, allowing direct plunge entry. Machinists and tooling specialists working in tight-tolerance applications rely on this geometry for small-feature work.

This end mill is suited for small-diameter milling operations in machining centers, CNC mills, and manual knee mills where fine detail and close tolerances are required. The 1/8 inch shank diameter fits standard collets and end mill holders commonly found in production and job shop environments. The 1-1/2 inch overall length keeps the tool rigid, reducing deflection during cuts. Typical applications include die and mold work, medical component machining, and aerospace detail parts where small feature sizes demand tight dimensional control.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating for elevated heat resistance and extended tool life
• 3 right-hand flutes with 30-degree helix for efficient chip evacuation and surface finish
• Center-cutting geometry allows direct plunge milling
• 1/8 inch shank diameter fits standard collets and end mill holders
• Right-hand cutting direction compatible with conventional CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual mills accepting a 1/8 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder to secure the 1/8 inch shank, and verify runout with a dial indicator before production use. Follow shop safety procedures and machine manufacturer guidelines for tool change and setup.
