Accupro 12182127 Corner Radius End Mill 3/4 in 3 Flute Carbide

Product Description

The ACCUPRO 12182127 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 3/4 inch mill diameter, a 1-1/2 inch length of cut, and a 0.045 inch corner radius that produces a consistent radiused edge on workpiece corners, reducing stress concentrations and improving surface finish. The tool is single-end, centercutting, and ground from micrograin carbide stock for edge retention and dimensional stability. It is installed and operated by machinists and CNC programmers working on mill machines, machining centers, and manual knee mills.

This end mill is suited for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials where a controlled corner radius is required. The bright uncoated finish makes it appropriate for applications where coating interaction with workpiece material is a concern, and for shops that regrind tooling after use. The 40-degree helix promotes efficient chip evacuation during side milling and full-slot passes. With a 3/4 inch shank diameter matching the cutter diameter, it seats directly in standard 3/4 inch collets or end mill holders without a reducer.

Key Features

• 0.045 inch corner radius for consistent radiused edges and reduced corner chipping on workpieces
• Micrograin solid carbide construction for rigidity and extended tool life
• 3 flutes with right-hand spiral and right-hand cutting direction
• 40-degree helix angle for effective chip evacuation in slotting and profiling cuts
• Centercutting geometry allows plunge entry into the workpiece
• Bright uncoated finish suitable for regrinding and dry or wet cutting applications

Compatibility

Designed as a standard 3/4 inch shank end mill compatible with 3/4 inch collet chucks, hydraulic holders, and end mill holders on vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and locked out before tooling changes. Seat the shank fully into the holder to the minimum clamping depth recommended for the holder type, and verify runout with a dial indicator before commencing cuts. Consult the machine tool manufacturer and applicable shop safety standards for proper spindle speed and feed rate selection based on material and cut depth.
