Harvey Tool 854162 Corner Radius End Mill 0.062in 3 Flute Carbide

Product Description

The HARVEY TOOL 854162 is a solid carbide corner radius end mill designed for precision material removal in miniature and close-tolerance machining applications. It features a 0.0620-inch cutting diameter, a 0.0100-inch corner radius with a tolerance of plus or minus 0.0010 inch, and a 3-flute spiral geometry with right-hand cutting direction. The stub-length design provides added rigidity in confined setups. With a bright, uncoated finish, this single-end centercutting tool handles both roughing and finishing passes across a range of workpiece materials. Licensed machinists and CNC tooling technicians are the primary users.

This end mill suits precision CNC milling work in steel, stainless steel, cast iron, non-ferrous metals, aluminum, wood, and composite materials. Its miniature form factor makes it well suited for die and mold work, micro-component machining, and any application requiring tight-radius corner blending in small cavities or slots. The 1/8-inch straight cylindrical shank fits standard collet-style toolholders used in vertical and horizontal CNC machining centers.

Key Features

• 0.0620-inch cutting diameter with a mill diameter tolerance of plus 0.0005 / minus 0.0005 inch
• 0.0100-inch corner radius tolerance held to plus or minus 0.0010 inch for accurate edge blending
• 3-flute solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 30-degree right-hand spiral helix promotes efficient chip evacuation in miniature slots
• Centercutting geometry allows direct plunge entry into workpiece material
• Bright, uncoated finish compatible with a wide range of workpiece materials including aluminum and composites

Compatibility

Compatible with standard collet-style toolholders accepting a 1/8-inch straight cylindrical shank. Designed for use across workpiece material classes including steel (ISO P), stainless steel (ISO M), cast iron (ISO K), and non-ferrous metals (ISO N).

Installation Notes

Installation is performed by qualified CNC machining technicians. Power down and lock out the machine spindle before changing tooling. Seat the 1/8-inch shank fully and evenly in the collet before torquing the toolholder to the machine specification. Verify runout at the cutting tip after installation, as miniature-diameter end mills are sensitive to collet concentricity errors that can reduce tool life and dimensional accuracy.
