Accupro 12180485 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12180485 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 3/16-inch diameter, a 5/8-inch length of cut, and a 0.01-inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding materials. The AlTiN coating improves heat resistance and wear performance at elevated cutting temperatures. With four flutes and a right-hand spiral flute direction, this single-end centercutting tool is suited for finishing and semi-finishing passes where tight tolerances and surface quality are required.

This end mill is used in CNC machining centers and manual mills for contouring, slotting, and profiling operations on ferrous metals, hardened steels, stainless, and similar alloys. The centercutting geometry allows plunge entry directly into the workpiece. The 2-inch overall length and 3/16-inch shank diameter make it appropriate for tight-clearance setups and small-feature work. It is installed and operated by machinists and tooling technicians in job shops, aerospace, and precision manufacturing environments.

Key Features

• AlTiN coating for extended tool life in high-temperature cutting conditions
• 0.01-inch corner radius reduces edge chipping and stress at the cutting corner
• Four-flute design improves surface finish and material removal efficiency
• Centercutting capability allows direct plunge milling
• Micrograin solid carbide substrate provides rigidity and wear resistance
• Variable index flute spacing reduces harmonic vibration during cutting

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC machining centers and manual milling machines accepting a 3/16-inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Secure the shank fully in a collet or end mill holder to the manufacturer-specified engagement depth before operation. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Do not exceed the tool's rated cutting parameters for the workpiece material.
