Harvey Tool 47878 Square End Mill 0.0780 in 3 Flute Carbide

Product Description

The HARVEY TOOL 47878 is a solid carbide square end mill designed for precision milling in demanding machining applications. With a cutting diameter of 0.0780 inches (5/64 inch) and a 3-flute geometry, this end mill delivers clean, accurate cuts in ferrous and non-ferrous materials. The 30-degree helix angle promotes efficient chip evacuation and reduces cutting forces. A bright, uncoated finish makes it suitable for use across a range of workpiece materials. Overall length is 2.5 inches with a 0.125-inch (1/8-inch) shank diameter, and the extended reach design provides access to deeper features without tool changes.

This end mill is suited for small-diameter milling work in job shop, tool-and-die, mold, and production machining environments. It handles slot milling, profiling, and contouring in applications where fine detail and tight tolerances are required. The centercutting capability allows direct plunge entry. Right-hand cut and right-hand flute orientation are standard for conventional CNC milling setups. Machinists working with small-feature aerospace, medical, or precision mechanical components will find this tool appropriate for tight-clearance work.

Key Features

• 0.0780 inch (5/64 inch) cutting diameter for small-feature precision work
• 3-flute solid carbide construction for rigidity and wear resistance
• 30-degree helix angle promotes chip flow and reduces cutting pressure
• Centercutting design allows direct plunge milling
• Extended reach with 0.234 inch reach length for deeper cavity access
• Bright, uncoated finish compatible with a wide range of materials

Compatibility

Designed as a standard shank replacement end mill for CNC machining centers and manual mills accepting a 0.125 inch (1/8 inch) collet or tool holder.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use an appropriate collet or end mill holder rated for the 0.125 inch shank diameter and verify tool runout with a dial indicator before production use. Follow the machine manufacturer and tooling manufacturer recommendations for speeds, feeds, and depth of cut when programming this tool.
