Accupro 12183460 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12183460 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and high cutting performance. Built from micrograin solid carbide and coated with TiCN for improved wear resistance and heat management, this tool handles ferrous and non-ferrous materials with consistent accuracy. The 0.02 inch corner radius reduces stress concentration at the cutting edge, extending tool life in demanding applications. With a 4-inch overall length and 1-inch length of cut, it is suited for reaches into pockets, slots, and contoured surfaces. Machinists and tool-and-die professionals are the primary installers and users of this end mill.

This end mill is used in vertical and horizontal CNC machining centers as well as manual knee mills for profiling, slotting, and side milling operations. The single-end, centercutting design allows plunge entry and full peripheral cutting. The 40-degree helix angle promotes chip evacuation and smooth cutting action. Its long-length classification makes it appropriate for applications requiring extended reach while maintaining rigidity through the solid carbide construction.

Key Features

• Micrograin solid carbide substrate for dimensional stability and edge retention
• TiCN coating improves surface hardness and reduces friction at the cutting edge
• 0.02 inch corner radius reduces chipping and stress at cutting corners
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed as a standard shank corner radius end mill compatible with 3/16 inch collets, end mill holders, and tool holders used in CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before tool changes. Seat the 3/16 inch shank fully into the collet or tool holder and tighten to the holder manufacturer's specified procedure to prevent pullout. Verify runout with a dial indicator before beginning production cuts when tight tolerances are required.
