Accupro 12184690 Ball End Mill 0.5625 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12184690 is a single-end ball end mill designed for precision milling operations in metal and alloy applications. Built from micrograin solid carbide, it offers superior hardness and wear resistance compared to high-speed steel alternatives. The cutting end features a 0.5625-inch diameter with a 1.25-inch length of cut and a 40-degree helix angle, promoting efficient chip evacuation and reduced chatter. An AlTiN coating provides thermal resistance and extends tool life in high-speed, dry, or semi-dry cutting conditions. Machinists and tool-and-die professionals rely on this end mill for contouring, slotting, and profiling in CNC machining centers.

This ball end mill suits contouring and 3D profiling work in ferrous metals, stainless steels, and hardened materials where surface finish and tool longevity are priorities. The 40-degree right-hand helix combined with four flutes supports aggressive material removal while maintaining finish quality. The 9/16-inch shank diameter matches standard collet and end mill holder sizes common in vertical and horizontal CNC machining centers used in job shops, tool rooms, and production environments.

Key Features

• Micrograin solid carbide construction for superior rigidity and wear resistance
• AlTiN coating for high-temperature resistance and extended tool life in ferrous and hardened materials
• 4-flute configuration balances chip evacuation with surface finish quality
• 40-degree right-hand helix angle reduces cutting forces and improves chip flow
• Single-end design with 3.5-inch overall length for reach in standard CNC setups
• Right-hand cutting direction compatible with conventional CNC spindle rotation

Compatibility

Designed as a direct-fit replacement or new-install ball end mill for CNC machining centers accepting a 9/16-inch shank diameter in standard collet chucks or end mill holders.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in a safe, locked-out state. Ensure the collet or tool holder is clean and free of chips before seating the shank. Confirm runout with a dial indicator before beginning a cut. Follow the machine tool manufacturer guidelines for feed rates and speeds when setting up a new tool.
