Harvey Tool 832930 Corner Radius End Mill 1/8 in 2 Flute

Product Description

The HARVEY TOOL 832930 is a miniature corner radius end mill ground from solid carbide for use in precision milling operations. The tool features a 1/8 inch cutting diameter with a 0.0300 inch corner radius and a 3/16 inch length of cut, making it well suited for producing blend radii and edge breaks on small features. A 2-flute, right-hand spiral design with a 30-degree helix angle supports efficient chip evacuation in both roughing and finishing passes. The bright uncoated finish is compatible with a broad range of workpiece materials. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as cut laterally.

This end mill is designed for use in CNC machining centers, vertical mills, and toolroom applications where tight tolerances and small-diameter tooling are required. Primary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. The stub-standard series designation indicates a shorter overall length profile, which improves rigidity and reduces deflection in close-clearance setups. The straight cylindrical shank mounts directly into standard collet-style toolholders.

Key Features

• 1/8 inch cutting diameter with 0.0300 inch corner radius for fine blending and edge profiling
• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 2-flute, right-hand spiral with 30-degree helix for efficient chip removal
• Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole
• Coarse pitch, uncoated finish suitable for aluminum, steel, stainless steel, cast iron, and composites
• Stub-standard length minimizes overhang and deflection in tight setups

Compatibility

Designed for use with standard collet-style toolholders accepting a 1/8 inch straight cylindrical shank. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool change cycle is complete before handling. Seat the shank fully into the toolholder collet and torque the clamping nut to the toolholder manufacturer specification. Verify runout at the cutting diameter before beginning a production run, as excessive runout accelerates wear and reduces corner radius accuracy on small-diameter carbide tooling.
