Harvey Tool 968778 Square End Mill 5/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 968778 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 5/64 inch (0.0780 inch) mill diameter and a 0.117 inch length of cut, this single-end tool is built for tight-tolerance work in small-diameter cutting situations. The 3-flute geometry with a variable helix angle improves chip evacuation and reduces chatter during cutting. The bright, uncoated finish is suitable for a range of workpiece materials where coating is not required. This end mill is installed and used by machinists and CNC operators working in job shops, production machining, and tool-and-die environments.

This end mill is suited for light-material removal, slotting, profiling, and peripheral milling passes where a small-diameter tool is required. The 1/8 inch shank diameter fits standard collets and tool holders used on CNC machining centers and manual mills. The 1-1/2 inch overall length keeps the tool rigid, which is critical when running small-diameter cutters at the elevated spindle speeds required for solid carbide tooling. Right-hand cutting and right-hand flute direction make it compatible with standard spindle rotation on conventional machine tools.

Key Features

• 5/64 inch (0.0780 inch) mill diameter for small-feature and tight-tolerance cutting
• 3-flute design with variable helix for improved chip flow and reduced vibration
• Solid carbide construction for rigidity and wear resistance
• Center-cutting capable, allowing direct plunge entry
• Bright/uncoated finish for use across a broad range of materials
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as a direct-fit replacement for small-diameter square end mill applications requiring a 1/8 inch shank and 5/64 inch cutting diameter in standard collet-style tool holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and locked out before tool changes. Ensure the shank is fully seated in the collet or tool holder to the recommended grip length before torquing the retention nut. Verify spindle speed and feed rate settings are appropriate for the workpiece material and tool diameter before engaging the cut. Handle solid carbide tooling carefully to avoid chipping the cutting edges.
