Harvey Tool 31630-C3 Corner Rounding End Mill 3/16 in

Product Description

The HARVEY TOOL 31630-C3 is a double-end corner rounding end mill designed to produce consistent edge radii on machined workpieces. Built from solid carbide with an AlTiN coating, this tool handles the thermal and abrasive demands of high-speed milling in ferrous and non-ferrous materials. The 0.03 mm corner radius produces a fine, controlled edge break, while the 2-flute geometry supports efficient chip evacuation. At 4 inches overall length with a 3/16 inch shank diameter, it fits standard collet toolholders used in CNC and manual milling setups. The double-end configuration doubles usable tool life before replacement is required.

This end mill is suited for CNC machining centers and manual mills in job shop, aerospace, die-and-mold, and general precision machining environments. It is applied wherever a controlled, uniform corner radius is required on part edges — particularly in applications where sharp edges must be eliminated for functional or cosmetic reasons. The small 0.03 mm radius makes it appropriate for fine detail work on close-tolerance components. Installation and operation are performed by machinists and CNC operators working with standard milling equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding milling applications
• AlTiN coating provides thermal protection and extended tool life at elevated cutting speeds
• 0.03 mm corner radius delivers precise, repeatable edge rounding on close-tolerance parts
• Double-end design provides two usable cutting ends per tool
• 2-flute geometry promotes chip clearance in lighter milling passes
• 3/16 inch shank diameter fits standard collet and toolholder systems

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 3/16 inch shank diameter collet or toolholder. Part of the Harvey Tool Corner Rounding End Mills - 2 and 4 Flute - Flared series.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank fully within a properly sized collet or toolholder and torque to the toolholder manufacturer specification before operation. Inspect both cutting ends for chipping or wear before each use. Follow all machine guarding and RPM recommendations for the workpiece material and tool diameter when setting up the cut.
