Harvey Tool 771252 Tapered Ball End Mill Solid Carbide

Product Description

The HARVEY TOOL 771252 is a solid carbide tapered ball end mill designed for precision milling in non-ferrous materials. Part of the Runner Cutters series, this tool features a 20-degree taper angle per side, a 0.02-inch small end diameter, and a 0.01-inch nose radius, making it well suited for fine detail work, tapered wall features, and confined-area profiling. With 2 flutes and a center-cutting design, it handles both plunge and peripheral cuts. The uncoated carbide construction is optimized for aluminum, brass, copper, and similar non-ferrous workpieces where coating reactivity or buildup is a concern.

This end mill fits standard CNC machining centers and manual mills equipped with a 1/8-inch collet or toolholder. It is intended for shops and toolrooms performing detailed contour milling, 3D surfacing, tapered slot work, and fine-feature engraving in non-ferrous stock. The 0.205-inch length of cut and 1.5-inch overall length make it appropriate for shallow-to-moderate depth applications where reach and rigidity must be balanced. Machinists, moldmakers, and precision fabricators working in aerospace, electronics, and general job shop environments are the primary users of this tool.

Key Features

• 20-degree taper angle per side for consistent tapered wall geometry
• 0.02-inch small end diameter with 0.01-inch nose radius for fine detail cuts
• Center-cutting design allows direct plunge entry into the workpiece
• Solid carbide construction delivers rigidity and wear resistance
• 2-flute configuration promotes chip evacuation in non-ferrous materials
• Uncoated finish suited for aluminum, brass, and other non-ferrous alloys

Compatibility

Designed for use in CNC machining centers and mills with a 1/8-inch collet or toolholder. Intended for non-ferrous materials as part of the Harvey Tool Runner Cutters series.

Installation Notes

Installation of this end mill requires a properly sized 1/8-inch collet or toolholder; ensure the holder is clean and free of runout before clamping. Power down and lock out the spindle before inserting or removing the tool. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for solid carbide end mills in non-ferrous applications. Avoid using this uncoated tool on ferrous materials, as it is not rated for that application.
