Harvey Tool 21050 Corner Rounding End Mill 3/8 in 4 Flute

Product Description

The HARVEY TOOL 21050 is a solid carbide corner rounding end mill engineered for producing consistent, repeatable radius profiles on workpiece edges. Built as a double-end tool with 4 flutes, it delivers a 0.05-inch corner radius on a 3/8-inch diameter cutter. The bright, uncoated carbide construction makes it suitable for a wide range of ferrous and non-ferrous materials where coating interaction is a concern. Machinists and CNC operators use this style of tool to break sharp edges, add controlled radius profiles, and improve part aesthetics or fatigue resistance in a single pass without secondary deburring operations.

This end mill fits standard CNC machining centers, manual mills, and tooling setups that accept a 3/8-inch shank. Its double-end configuration extends tool life by offering a second usable cutting end, reducing per-part tooling cost in production environments. Typical applications include edge profiling on aluminum, steel, stainless, and plastics in job shop, production, and prototype machining scenarios. The flared series geometry is designed to maintain proper chip clearance and surface finish quality throughout the full radius cut.

Key Features

• 0.05-inch corner radius for precise, repeatable edge profiling
• Solid carbide construction for rigidity and wear resistance
• 4-flute design for improved surface finish and feed rates
• Double-end configuration extends usable tool life
• Bright, uncoated finish suitable for dry cutting and a broad range of materials
• Flared series geometry supports chip evacuation during radius operations

Compatibility

Designed for use in CNC machining centers and manual milling machines with a 3/8-inch collet or chuck. Fits standard ER and straight-bore toolholders accepting a 3/8-inch shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power isolated. Ensure the shank is clean and fully seated in the toolholder before tightening to the appropriate collet nut torque per the toolholder manufacturer specifications. Inspect both cutting ends for chipping or wear before each use. Follow your machine tool manufacturer guidelines for runout verification after tool installation.
