Accupro 35654441 Ball End Mill 1/2 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 35654441 is a single-end ball end mill designed for precision milling operations in ferrous and hardened materials. Built from solid carbide and coated with AlTiCrN, it delivers heat resistance and wear performance in demanding cutting applications. The 1/2 inch diameter tool features 4 flutes with a variable index geometry, a 0.4660 inch length of cut, and a 0.3120 inch neck length. At 3 inches overall length with a 1/2 inch shank diameter, it fits standard end mill holders used by machinists and tooling professionals in job shop and production environments.

This ball end mill is suited for profiling, contouring, and finishing cuts in ferrous alloys, stainless steels, and hardened steels where AlTiCrN coating provides thermal stability at elevated cutting speeds. The variable index flute spacing reduces chatter and harmonics during aggressive passes. It is a single-end tool, meaning the cutting end is not reversible, and it is sized for 1/2 inch collets or end mill holders on vertical machining centers and CNC mills.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiCrN coating provides high-temperature oxidation resistance and extended tool life
• 4-flute, variable index design reduces harmonic chatter during contouring passes
• 0.4660 inch length of cut with 0.3120 inch neck length for reach into pockets and contours
• Single-end configuration with 1/2 inch shank for secure clamping in standard holders

Compatibility

Designed as a direct-fit replacement for 1/2 inch shank ball end mills used in standard end mill holders, collet chucks, and shrink-fit tooling on vertical and horizontal CNC machining centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in an E-stop or locked-out state per applicable shop safety procedures. Ensure the shank is fully seated in the holder to the recommended gauge line before torquing the collet nut or set screw. Inspect the cutting edges and coating for chips or damage before each use. Follow the tooling manufacturer and machine builder guidelines for speeds, feeds, and depth of cut when programming this tool.
