Accupro 12182112 Corner Radius End Mill 5/8 in 3 Flute Altin

Product Description

The ACCUPRO 12182112 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8 inch cutting diameter, a 1-1/4 inch length of cut, and a 0.015 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The micrograin carbide substrate and AlTiN coating allow this tool to handle higher cutting temperatures and abrasive workpiece materials. It is a single-end, centercutting design with a 3-flute configuration and a 40-degree helix angle. This end mill is installed and operated by machinists and tooling technicians on CNC milling machines and manual mills.

This end mill is suited for slotting, profiling, and contouring operations in ferrous and non-ferrous metals, hardened steels, and cast iron. The AlTiN coating provides oxidation resistance at elevated temperatures, making it appropriate for dry or minimal-lubrication machining strategies. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC mill setups. It is applicable in job shops, production machining cells, and tool rooms where tight tolerances and surface finish quality are required.

Key Features

• 0.015 inch corner radius reduces edge chipping and improves surface finish on contoured profiles
• AlTiN coating provides heat and wear resistance for extended tool life in high-temperature cutting
• Micrograin solid carbide substrate delivers rigidity and dimensional stability
• 3-flute geometry balances chip evacuation and feed rate capability
• 40-degree helix angle promotes smooth cutting action and reduced cutting forces
• Centercutting design allows plunge entry into the workpiece

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC and manual milling machines accepting a 5/8 inch shank diameter collet or end mill holder.

Installation Notes

This end mill is installed by qualified machinists using an appropriate collet chuck or end mill holder rated for the 5/8 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout at the cutting diameter after installation to confirm proper seating and avoid premature edge wear. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the workpiece material and coating type.
