Harvey Tool 49878 Square End Mill 0.0781 in 2 Flute Carbide

Product Description

The HARVEY TOOL 49878 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0781 inch (5/64 inch) cutter diameter and a 0.125 inch shank diameter, this tool is built for small-feature work where tight tolerances and clean edge geometry are critical. The 2-flute upcut configuration clears chips efficiently from the cut zone, and the 20-degree helix angle balances cutting forces for smooth tool engagement. A bright, uncoated finish keeps the tool at its as-ground diameter for applications where coating buildup at this scale would affect fit. Machinists and tool-and-die professionals install this type of end mill in CNC machining centers and manual mills.

This end mill suits fine-detail milling operations on ferrous and non-ferrous workpiece materials where a small-diameter, short-reach tool is required. The 0.406 inch length of cut and 2 inch overall length position this tool for shallow slotting, profiling, and pocketing passes on small components. Right-hand cut with right-hand flute orientation makes it compatible with standard spindle rotation on conventional vertical milling setups. It is a single-end tool, meaning it is replaced rather than flipped when worn.

Key Features

• 0.0781 inch (5/64 inch) cutter diameter for small-feature precision work
• Solid carbide construction for rigidity and wear resistance at small diameters
• 2-flute upcut geometry promotes chip evacuation in shallow slots and pockets
• 20-degree helix angle balances cutting forces and reduces deflection
• Bright, uncoated finish preserves as-ground cutter diameter
• Right-hand cut, single-end configuration for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 0.125 inch collets or tool holders on CNC machining centers and manual vertical mills requiring small-diameter milling capability.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and de-energize the spindle fully before changing tooling. Seat the 0.125 inch shank fully in the collet or end mill holder and torque the retention hardware to the tool holder specification before running. Inspect the cutter edge under magnification before use, as solid carbide tools at this diameter are brittle and can arrive damaged if mishandled.
