Harvey Tool 970550-C6 Ball End Mill 0.05 in 3 Flute Carbide

Product Description

The HARVEY TOOL 970550-C6 is a solid carbide ball end mill engineered for high-temperature alloy machining. It features a 0.0500-inch mill diameter, a 0.1500-inch length of cut, and three flutes with a variable helix angle of 34 degrees. The AlTiN Nano PVD coating provides thermal resistance and hardness retention at elevated cutting temperatures. At 1.5000 inches overall length with a 0.1250-inch straight-cylindrical shank, this single-end tool is designed for precision milling in demanding aerospace, medical, and energy applications. Installation and operation are performed by machinists and CNC tooling professionals.

This end mill is designed for primary use in high-temperature alloys, including nickel, titanium, and cobalt-based materials, identified under workpiece material code S. It also performs in secondary materials including steel, stainless steel, cast iron, and hardened materials (material codes P, M, K, and H). The variable helix geometry reduces harmonic vibration and improves chip evacuation in difficult-to-machine alloys. Typical applications include finish and roughing passes in tight-tolerance features, slots, and contoured surfaces in CNC milling environments.

Key Features

• 0.0500-inch ball end diameter with 0.0250-inch nose radius for fine-detail and contour work
• Variable helix design at 34 degrees reduces chatter and improves stability in high-temp alloy cuts
• AlTiN Nano PVD coating delivers heat resistance and extended tool life in abrasive materials
• Three-flute, right-hand spiral configuration supports efficient chip removal and centercutting capability
• Solid carbide construction provides rigidity and wear resistance across a broad range of workpiece materials
• Straight-cylindrical shank with h6 tolerance ensures consistent tool holding in standard collets and end mill holders

Compatibility

Designed for use with high-temperature alloys (material code S) as the primary workpiece material, with secondary compatibility across steel, stainless steel, cast iron, and hardened materials. Part of the HARVEY TOOL Variable Helix End Mills for High Temp Alloys - Ball series within the Material Specific End Mills product family.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a safe, locked-out state. Use a precision collet or end mill holder rated for the 0.1250-inch shank diameter to ensure runout is minimized. Verify tool projection and reach requirements before beginning a cutting program, especially in deep-pocket or confined-geometry applications. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds and feeds specific to the workpiece material and tool diameter.
