Harvey Tool 941530-C3 Corner Rounding End Mill 3/16 in

Product Description

The HARVEY TOOL 941530-C3 is a double-end corner rounding end mill designed to produce consistent edge radii on ferrous and non-ferrous workpieces in milling operations. It features a 0.03 mm corner radius and a 3/16 inch mill diameter, with a solid carbide substrate that provides the rigidity and heat resistance required for high-speed contouring and finishing passes. The AlTiN coating increases surface hardness and oxidation resistance, making the tool well-suited for dry or semi-dry cutting in hardened steels, stainless, and titanium alloys. With two flutes and a double-end configuration, the tool offers extended service life per unit.

This end mill is intended for use on CNC machining centers and manual mills where edge-breaking, radius blending, or decorative corner rounding is required. The 1/8 inch tip diameter and 3/16 inch shank make it appropriate for light to moderate material removal on close-tolerance features. It fits standard 3/16 inch collets or end mill holders and is suited for shop environments handling precision components in aerospace, medical device, die-mold, and general metalworking applications. Licensed machinists and CNC programmers are the primary installers and users of this tooling.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cut conditions
• AlTiN coating extends tool life in high-temperature, hard-material applications
• Double-end design provides two usable cutting ends per tool
• 0.03 mm corner radius for fine, precise edge profiling
• 2-flute geometry supports efficient chip evacuation in ferrous and non-ferrous materials
• Flared series profile maintains clearance during radial engagement

Compatibility

Part of the Harvey Tool Corner Rounding End Mills - 2 and 4 Flute - Flared series. Fits standard 3/16 inch collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC tooling and milling operations. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Confirm collet runout is within acceptable tolerance before engaging the cut, as excess runout accelerates edge wear on small-diameter carbide tools. Follow the machine tool manufacturer and tooling manufacturer guidelines for speed and feed recommendations appropriate to workpiece material and depth of cut.
