Harvey Tool 958893-C3 Corner Radius End Mill 0.093in 4 Flute

Product Description

The HARVEY TOOL 958893-C3 is a miniature stub-series corner radius end mill designed for precision milling in tight-tolerance applications. Built from solid carbide with an AlTiN PVD coating, it handles steel, stainless steel, cast iron, and non-ferrous metals in both roughing and finishing operations. The tool measures 0.093 inches in diameter with a 0.03-inch corner radius, a 0.14-inch length of cut, and a 1.5-inch overall length. With 4 right-hand spiral flutes and a 30-degree helix angle, it delivers efficient chip evacuation and a consistent surface finish. Licensed machinists and CNC tooling technicians are the primary users of this tool.

This end mill fits residential shop, production, and job-shop CNC milling environments where small-diameter, high-precision cuts are required. It is well suited for contouring, slotting, and profiling operations on steel, stainless steel, cast iron, composites, and non-ferrous materials. The stub-length geometry provides added rigidity compared to standard-reach miniature end mills, making it appropriate for applications where deflection control is critical. It is a single-end, centercutting tool compatible with straight cylindrical toolholders accepting a 0.125-inch shank.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating extends tool life in steel and stainless steel applications
• 0.03-inch corner radius reduces stress concentration and improves edge durability
• 4 right-hand spiral flutes with 30-degree helix for efficient chip removal
• Centercutting design allows plunge entry
• Stub-length geometry increases rigidity and reduces deflection in small-diameter milling

Compatibility

Designed for use with straight cylindrical toolholders accepting a 0.125-inch shank diameter. Suitable for machining steel, stainless steel, cast iron, non-ferrous metals, and composites as listed in the manufacturer specifications.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Ensure the toolholder collet or chuck matches the 0.125-inch shank diameter and that runout is minimized before operation. Follow machine manufacturer guidelines and applicable shop safety protocols when setting tool offsets and establishing cut parameters. Do not exceed the rated length of cut of 0.14 inches during axial engagement.
