Accupro 14788488 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 14788488 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 3/8 inch diameter cutting face with a 0.0900 inch corner radius, a 4-flute spiral geometry, and an AlTiN+ coating that provides heat resistance and extended tool life at elevated cutting speeds. The overall length is 2.5 inches with a 7/8 inch length of cut. This is a single-end, centercutting tool, meaning it can plunge directly into material as well as perform peripheral and slot milling. Machinists and tool-and-die professionals typically install and run this end mill on CNC machining centers and manual mills.

This end mill is suited for milling operations on hardened steels, stainless, and high-temp alloys where a corner radius is required to reduce stress concentrations and improve surface finish at part edges. The right-hand cutting direction and spiral flute design support efficient chip evacuation in both roughing and finishing passes. It is a single-end tool, so the shank end is not a cutting surface. Typical applications include die cavities, mold details, stepped pockets, and contoured profiles where a sharp corner is not acceptable by design or specification.

Key Features

• 0.0900 inch corner radius reduces edge stress concentration and improves surface finish on milled profiles
• AlTiN+ coating provides high hardness and oxidation resistance for extended tool life in ferrous and high-temp alloys
• 4-flute spiral geometry supports efficient chip evacuation and higher feed rates versus 2-flute designs
• Centercutting design allows direct plunge entry without pre-drilling
• Solid carbide construction delivers rigidity and dimensional stability in close-tolerance applications
• Right-hand cutting direction compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as an OEM-style solid carbide corner radius end mill suitable for use in standard milling tool holders accepting a 3/8 inch shank diameter.

Installation Notes

This tool should be installed by a qualified machinist using an appropriate end mill holder, collet chuck, or hydraulic holder rated for the shank diameter. Ensure the spindle is fully stopped and machine is in a safe state before inserting or removing the tool. Verify runout with a dial indicator after tool installation to maintain dimensional accuracy. Follow the machine tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
