Accupro 12184973 1/8 Inch Roughing Finishing End Mill

Product Description

The ACCUPRO 12184973 is a solid carbide roughing finishing end mill designed for aggressive material removal with a quality surface finish in a single tool. Built with a chipbreaker geometry and a 40-degree helix angle, it improves chip evacuation and reduces cutting forces during roughing passes. The AlTiN coating adds heat and wear resistance, making it well-suited for harder workpiece materials. At 0.125 inches in diameter with a 0.5 inch length of cut and 1.5 inch overall length, this is a compact, single-end tool intended for use on CNC machining centers and manual mills. It is installed and set up by machinists and tooling technicians.

This end mill is built for applications in aerospace, die and mold, and general precision machining where a right-hand, center-cutting tool is needed at a small diameter. The straight shank and regular length make it compatible with standard collet chucks and end mill holders. The micrograin carbide substrate supports higher cutting speeds and delivers longer tool life compared to standard carbide grades, particularly in hardened steels, stainless alloys, and cast iron. Single-end configuration means the cutting end is not reversible.

Key Features

• Chipbreaker geometry reduces cutting forces and improves chip control during roughing passes
• AlTiN coating provides elevated heat resistance for dry or high-speed cutting applications
• 40-degree helix angle promotes smooth chip evacuation in deep pockets and slots
• Micrograin solid carbide substrate supports higher surface footage and extended tool life
• Center-cutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed as a standard straight-shank end mill compatible with collet chucks, ER collet systems, and end mill holders sized for a 0.125 inch shank diameter.

Installation Notes

Installation is performed by a machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool is secured with the correct collet or holder torqued to the manufacturer specification for that holder type. Verify runout with a dial indicator before cutting, as even small runout values at this diameter can significantly reduce tool life. Follow shop-specific speeds and feeds for the workpiece material and coating type.
