Harvey Tool 45262 Corner Radius End Mill 0.062 in 2 Flute

Product Description

The HARVEY TOOL 45262 is a miniature solid carbide corner radius end mill designed for precision material removal in tight-tolerance machining applications. It features a 0.0620-inch mill diameter, a 0.0100-inch corner radius, and a 2-flute spiral design that supports both roughing and finishing passes in a single tool. The 30-degree helix angle promotes efficient chip evacuation while maintaining surface quality. With a bright, uncoated finish, this end mill is ready to run as-delivered on compatible ferrous and non-ferrous workpiece materials. It is center-cutting and single-ended, allowing plunge entry where required. Licensed machinists and CNC operators working in tool and die, medical, and aerospace environments are the primary users.

This end mill is suited for light to moderate stock removal on steel, stainless steel, cast iron, aluminum, composites, and wood. Its miniature diameter makes it appropriate for fine-detail contouring, slotting, and profiling where standard-diameter tooling cannot reach. The stub and standard series geometry keeps the tool stiff to minimize deflection in close-tolerance cuts. It fits straight-cylindrical toolholders with a 1/8-inch bore and is compatible with standard CNC milling machines and manual knee mills equipped with appropriate high-speed spindles.

Key Features

• 0.0620-inch mill diameter with 0.0005/-0.0005-inch diameter tolerance for precise fitment
• 0.0100-inch corner radius with tolerance of 0.0010 to -0.0010 inches
• Solid carbide construction for rigidity and wear resistance in hard materials
• 2-flute, right-hand spiral, right-hand cutting geometry suitable for both roughing and finishing
• Center-cutting design allows direct plunge entry
• Bright, uncoated finish — ready to use out of the box with no additional prep
• 1/8-inch straight-cylindrical shank fits standard miniature toolholders

Compatibility

Designed for use with standard straight-cylindrical toolholders accepting a 1/8-inch shank diameter. Primary workpiece material codes P, M, K, N, and O cover steel, stainless steel, cast iron, non-ferrous metals, and non-ISO materials per the input data.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and locked out per facility lockout/tagout procedures. Ensure the toolholder bore is clean and free of chips before seating the shank to the specified depth. Do not overtighten set screws beyond the toolholder manufacturer's recommendation. Confirm runout with a dial indicator before initiating a cut, as excessive runout on a miniature-diameter end mill accelerates tool wear and risks breakage.
