Accupro 12183179 Corner Radius End Mill 1in 4-flute Altin

Product Description

The ACCUPRO 12183179 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and hardened materials. It features a 1 inch mill diameter, a 3 inch length of cut, and a 1/8 inch (0.1250 inch) corner radius that reduces stress concentration at the cutting edge and extends tool life. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating provides thermal resistance for demanding dry or semi-dry machining conditions. This tool is single-end, centercutting, and intended for use on CNC machining centers by skilled machinists or tool-and-die professionals.

This end mill is suited for slotting, profiling, and pocket milling operations where a radiused corner is required to meet part geometry or improve tool durability. The extra-long overall length of 6 inches accommodates deep-pocket and extended-reach applications common in mold making, die work, and aerospace component machining. The right-hand flute direction and right-hand cutting geometry are standard for conventional CNC spindle configurations. It is packaged as a single unit.

Key Features

• 1 inch mill diameter with mill diameter tolerance of +0.000000 to -0.002500 inches for precise fit and repeatable results
• 1/8 inch corner radius (0.1250 inch) with corner radius tolerance of 0.00150 inches
• AlTiN coating for high-temperature resistance and extended tool life in ferrous and hardened materials
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Solid carbide micrograin construction for rigidity and wear resistance
• Centercutting capability allows plunge entry into the workpiece
• Extra-long 6 inch overall length for deep-pocket and extended-reach applications

Compatibility

Designed as a direct-fit replacement-style solid carbide corner radius end mill for standard 1 inch shank tool holders used on CNC vertical and horizontal machining centers requiring right-hand cutting, single-end geometry.

Installation Notes

This end mill is installed by a machinist into a compatible 1 inch bore tool holder such as a collet chuck, end mill holder, or hydraulic chuck on a CNC machining center. Ensure the shank is fully seated and the tool holder is torqued to the machine manufacturer's specification before running. Verify runout at the tool tip before beginning a production cut. Always follow shop-floor lockout procedures when changing tooling in a live spindle.
