Harvey Tool 75240 Corner Radius End Mill 0.1562in 4 Flute

Product Description

The HARVEY TOOL 75240 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. With a 0.1562-inch (5/32 inch) mill diameter and a 0.04-inch corner radius, it delivers edge protection and a blended radius at the cutting corner that extends tool life and improves surface finish. The 4-flute, right-hand spiral geometry supports both roughing and finishing passes in a single tool. Overall length is 2 inches with a 9/16-inch length of cut and a 3/16-inch straight cylindrical shank. This miniature end mill is part of the Stub and Standard series, built for close-tolerance work on milling machines and CNC machining centers.

This end mill is suited for machining steel, stainless steel, cast iron, aluminum, non-ferrous metals, wood, and composite materials. Its compact stub-standard geometry makes it a practical choice for shallow pocket milling, profiling, and contouring where a miniature tool diameter is required. The bright uncoated carbide substrate is well-matched to applications where coating is unnecessary or where regrinding is anticipated. Machinists and CNC operators working in job shops, aerospace, medical device, and general precision machining environments will find it applicable across a wide range of workpiece materials.

Key Features

• 0.04-inch corner radius with a tolerance of plus or minus 0.001 inch for consistent edge geometry
• Solid carbide construction for rigidity and wear resistance in hard materials
• 4 right-hand spiral flutes with centercutting capability for plunge entry
• Bright uncoated finish suitable for aluminum and ferrous applications
• Normal pitch, fixed helix, no chipbreaker — optimized for standard milling operations
• Compatible with standard cylindrical toolholders via 3/16-inch straight shank

Compatibility

Designed for use with standard cylindrical toolholders. Fits machining centers and manual milling equipment accepting a 3/16-inch straight cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the toolholder and spindle are clean and free of debris before seating the shank. Verify runout with a dial indicator before cutting, as miniature end mill diameters are sensitive to even small amounts of TIR. Follow machine tool manufacturer guidelines for speed and feed parameters appropriate to the workpiece material and depth of cut.
