Accupro 12183567 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12183567 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/2 inch mill diameter, a 1 inch length of cut, and a 0.045 inch corner radius that reduces stress concentrations at the tool tip and extends tool life compared to sharp-corner geometries. The 4-flute, single-end design with a 40-degree right-hand helix promotes efficient chip evacuation and smooth surface finishes. A TiCN coating adds surface hardness and wear resistance for use in ferrous and non-ferrous materials. Machinists and CNC tool room operators are the primary users of this tool.

This end mill is suited for slot milling, peripheral milling, and profiling operations on machining centers and CNC mills. The long-length classification, 4 inch overall length, and centercutting capability allow it to plunge directly into the workpiece and reach deeper features. The micrograin carbide substrate supports higher cutting speeds and feeds in hardened steels, stainless steels, cast iron, and aluminum alloys. It is appropriate for both job shop and production environments where tight tolerances and repeatable surface quality are required.

Key Features

• 0.045 inch corner radius reduces chipping and improves surface finish at step transitions
• TiCN coating provides enhanced wear resistance and surface hardness for ferrous and non-ferrous cutting
• 4-flute spiral configuration with 40-degree helix angle promotes chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Micrograin solid carbide substrate supports high cutting speeds and extended tool life
• Right-hand flute direction and right-hand cutting compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting 1/2 inch straight shank end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the tool. Use a properly sized ER or DA collet, or a side-lock holder rated for the 1/2 inch shank diameter, and verify runout with a dial indicator before initiating a cut. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material.
