Harvey Tool 864662 Corner Radius End Mill 0.062 in 3 Flute

Product Description

The HARVEY TOOL 864662 is a miniature solid carbide corner radius end mill designed for precision milling in tight geometries and small-feature work. At 0.062 inches in diameter with a 0.0100-inch corner radius, this single-end tool is built for stub and standard-length applications where rigidity and accuracy matter. The 3-flute, right-hand spiral design supports both roughing and finishing passes in a single setup. With a bright, uncoated finish and a 30-degree helix angle, it is well-suited for machinists who need predictable performance across a range of workpiece materials without the added variables of a proprietary coating.

This end mill is intended for use in CNC machining centers, manual mills, and high-speed spindles where small-diameter tooling is required. Typical applications include contouring, slotting, and profiling in steel, stainless steel, cast iron, aluminum, non-ferrous metals, composites, and wood. The centercutting geometry allows plunge entry, adding flexibility in complex toolpath strategies. It fits standard toolholders accepting a 0.125-inch straight cylindrical shank. Machinists working in mold-and-die, medical components, aerospace detail parts, and general precision machining will find this tool applicable to a wide range of small-feature operations.

Key Features

• 0.0100-inch corner radius with a tolerance of plus or minus 0.0010 inches for consistent edge geometry
• 3-flute spiral configuration supports both roughing and finishing in a single tool
• Centercutting design permits direct plunge entry into workpiece material
• Solid carbide construction provides rigidity and wear resistance at small diameters
• Bright, uncoated finish eliminates coating variables, suitable for aluminum and non-ferrous applications
• Right-hand cut and right-hand flute direction for compatibility with standard CNC spindle rotation

Compatibility

Compatible with standard toolholders accepting a 0.125-inch straight cylindrical shank. Part of the HARVEY TOOL Miniature End Mills Corner Radius Stub and Standard series. Suitable for workpiece materials including steel, stainless steel, cast iron, aluminum, non-ferrous metals, composites, and wood.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or toolholder that matches the 0.125-inch shank diameter to prevent runout, which is especially critical at this diameter. Verify tool projection and stick-out are minimized to maintain rigidity when milling with small-diameter carbide end mills.
