Accupro 12182431 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12182431 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It measures 3/16 inches in diameter with a 5/8 inches length of cut and a 0.045 inches corner radius that helps reduce stress concentration at the cutting edge. The 2 inches overall length and 3/16 inches shank diameter keep the tool compact for close-tolerance work. An AlTiN coating provides heat and wear resistance, extending tool life during high-speed cutting in ferrous and hard materials. This tool is installed and used by machinists and CNC operators working in job shops, tool rooms, and production environments.

This end mill is suited for slotting, profiling, and contouring passes in ferrous metals, stainless steels, and high-temperature alloys where a corner radius is required to improve edge strength and surface finish. The single-end, centercutting design allows plunge entry as well as conventional peripheral milling. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC mill setups. The 40-degree helix angle promotes chip evacuation and reduces cutting forces during finish passes.

Key Features

• 0.045 inches corner radius reduces edge chipping and improves workpiece surface finish
• AlTiN coating provides oxidation resistance and extended tool life in dry and hard-material cutting
• Solid micrograin carbide substrate for rigidity and dimensional stability under load
• Centercutting design allows direct plunge milling without pre-drilled entry
• 4 flutes with 40-degree helix angle for efficient chip evacuation and smooth cutting action
• Single-end configuration with right-hand cut and right-hand spiral fluting

Compatibility

Designed as an OEM-style replacement or direct-use corner radius end mill for standard 3/16 inches collet or end mill holders on vertical machining centers, CNC mills, and manual knee mills.

Installation Notes

Installation is performed by machinists using a compatible collet chuck or end mill holder sized for a 3/16 inches shank. Confirm shank runout is within machine and holder tolerances before engaging a cut. Always power down and lock out the spindle before changing tooling. Follow shop-standard speeds and feeds for AlTiN-coated carbide end mills appropriate to the workpiece material.
