Harvey Tool 831960 Corner Radius End Mill 3/16in Solid Carbide

Product Description

The HARVEY TOOL 831960 is a solid carbide corner radius end mill designed for high-precision milling in ferrous and non-ferrous materials. With a 3/16 inch diameter, a 0.06 inch corner radius, and three right-hand helical flutes at a 30-degree helix angle, this tool delivers clean edge profiles and blended corner transitions in a single pass. The uncoated bright finish suits applications where coating interaction with the workpiece is a concern. At 2 inches overall length with a 5/8 inch length of cut, this is a stub-length geometry built for rigidity in tight-tolerance work. Machinists and tool-and-die professionals use it for profiling, slotting, and finishing operations in steel, stainless steel, cast iron, and non-ferrous metals.

This end mill fits within the Harvey Tool Miniature End Mills - Corner Radius - Stub and Standard series. It is suited for CNC machining centers and manual mills using a compatible straight-shank toolholder. The 3/16 inch shank diameter matches the cutter diameter for direct collet or end mill holder mounting. Typical applications include contour milling, cavity work, and edge blending where a controlled radius is required at the base of a wall or floor transition. The centercutting design allows plunge entry where needed. It is used across job shops, aerospace component shops, medical device machining, and precision mold work.

Key Features

• Solid carbide construction for rigidity and wear resistance in ferrous and non-ferrous materials
• 0.06 inch corner radius with a tolerance of plus 0.0010 to minus 0.0010 inches for repeatable edge blending
• Three right-hand flutes with 30-degree helix angle for efficient chip evacuation in roughing and finishing
• Centercutting geometry allows direct plunge entry without pre-drilling
• Stub-length design provides added rigidity for deflection-sensitive tight-tolerance applications
• Uncoated bright finish compatible with a broad range of workpiece materials including aluminum and composites

Compatibility

Compatible with standard straight-shank toolholders and collet systems accepting a 3/16 inch shank diameter. Suitable for steel, stainless steel, cast iron, aluminum, non-ferrous metals, wood, and composite workpiece materials.

Installation Notes

Installation is performed by a machinist or CNC operator. Secure the shank fully within the collet or toolholder to the recommended grip length before tightening. Verify spindle runout with a test indicator before starting a production run, as runout directly affects corner radius accuracy. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
