Accupro 12182603 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12182603 is a solid carbide corner radius end mill designed for precision milling operations in metal-cutting applications. It features a 1/2 inch mill diameter, a 1 inch length of cut, and a 0.09 inch corner radius that produces a controlled edge radius on workpiece features, reducing stress concentrations and improving surface finish. The TiCN coating extends tool life in ferrous and non-ferrous materials by increasing surface hardness and reducing friction. With 4 right-hand spiral flutes and a centercutting geometry, this end mill handles both plunge and profile operations. It is installed and operated by machinists and tooling professionals in CNC and manual milling environments.

This end mill is suited for general-purpose profiling, slotting, and contouring in shop and production settings. The 1/2 inch shank diameter fits standard ER and side-lock toolholders common to vertical machining centers and knee mills. The single-end configuration and 3 inch overall length make it appropriate for typical reach requirements in die-and-mold, aerospace, and general fabrication work. Micrograin carbide substrate supports higher surface footage and feeds compared to standard carbide grades.

Key Features

• Solid micrograin carbide substrate for improved wear resistance and edge retention
• TiCN coating for extended tool life in ferrous and non-ferrous materials
• 0.09 inch corner radius reduces edge chipping and improves part surface finish
• 4 right-hand spiral flutes with centercutting capability for plunge and profile milling
• 40-degree helix angle promotes efficient chip evacuation
• Single-end design with 1/2 inch shank for broad toolholder compatibility

Compatibility

Designed as a standard 1/2 inch shank corner radius end mill compatible with ER collet chucks, side-lock holders, and similar toolholding systems used on CNC vertical machining centers and manual knee mills accepting 1/2 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked before inserting or removing the end mill. Confirm shank seating depth meets the toolholder manufacturer's minimum engagement specification before tightening. Inspect the cutting edges and corner radius for chips or damage before each use, and do not exceed the tool's rated depth-of-cut for the workpiece material.
