Accupro 12183101 Corner Radius End Mill 1/2 in 4 Flute Altin

Product Description

The ACCUPRO 12183101 is a solid carbide corner radius end mill designed for precision milling in ferrous and hard materials. It features a 1/2 inch cutting diameter, a 2 inch length of cut, and a 0.03 inch corner radius that reduces stress concentrations at the tool tip and extends surface finish quality in profiling and contouring operations. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating provides high-temperature hardness and oxidation resistance, making this tool well-suited for dry or high-speed machining environments. This end mill is single-end, center-cutting, and right-hand cutting with a right-hand flute direction.

This tool is used in CNC machining centers for profiling, slotting, and peripheral milling in materials such as hardened steels, stainless steels, titanium, and heat-resistant alloys. The long-length flute geometry and micrograin carbide substrate make it appropriate for applications requiring reach into deeper pockets or along taller part features. It is installed by machinists and CNC operators in job shops, aerospace, automotive, and precision manufacturing environments.

Key Features

• 0.03 inch corner radius reduces tool stress and improves corner surface finish
• AlTiN coating delivers high-temperature hardness for dry and high-speed cutting
• 40-degree helix angle promotes chip evacuation and reduces cutting forces
• Micrograin solid carbide substrate provides rigidity and wear resistance
• Center-cutting design allows plunge entry into workpiece material
• Right-hand cut and right-hand spiral flute configuration for standard CNC spindle use

Compatibility

Designed as a direct-fit replacement for 1/2 inch shank corner radius end mills in standard ER or straight-bore CNC tool holders requiring a 1/2 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator following shop safety procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a calibrated tool holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout at the cutting diameter with a dial indicator before beginning production cuts.
