Harvey Tool 75100-C3 Tapered Ball End Mill Solid Carbide

Product Description

The HARVEY TOOL 75100-C3 is a solid carbide tapered ball end mill designed for precision milling in tight-geometry and deep-cavity applications. It features a 15-degree taper angle per side and a small end diameter of 0.03 inches, making it well-suited for fine detail work in hardened materials and complex part profiles. The AlTiN coating provides thermal resistance and extended tool life in high-speed cutting environments. With 2 flutes and a 12-degree helix angle, this mill balances chip evacuation with cutting stability. It is installed and operated by machinists and CNC programmers running close-tolerance work.

This end mill is part of the Harvey Tool Runner Cutters series and is intended for use in CNC machining centers and high-speed milling applications where tapered geometry is required to reach recessed floors or angled walls. With a 0.19-inch length of cut and 1/8-inch shank diameter, it is suited for small-scale detail milling in mold making, die work, and precision part manufacturing. It performs in both dry and minimal-lubrication cutting strategies common with AlTiN-coated tooling.

Key Features

• 15-degree taper angle per side for accurate tapered wall geometry
• 0.03-inch small end diameter with 1/64-inch nose radius for fine detail cuts
• AlTiN coating for high heat resistance and extended tool life in hard materials
• 2-flute, 12-degree helix design balances chip flow and cutting stability
• Solid carbide construction for rigidity and dimensional accuracy
• Runner Cutters series with 1/8-inch shank for standard collet compatibility

Compatibility

Designed as an OEM-style replacement and standard option for CNC machining setups requiring tapered ball end mills with a 1/8-inch shank in the Runner Cutters series.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder sized for a 1/8-inch shank. Ensure the spindle is fully powered down and the tool holder is clean and free of debris before seating the tool. Verify runout with a dial indicator before beginning cuts, as small-diameter tapered end mills are sensitive to tool deflection. Follow the machine manufacturer and tooling series guidelines for feed rate and spindle speed when working with AlTiN-coated carbide tooling.
