Accupro 12184906 Ball End Mill 0.375 in 4 Flute Carbide

Product Description

The ACCUPRO 12184906 is a solid carbide ball end mill designed for high-performance milling in demanding machining environments. With a 0.375 inch diameter and four flutes, this single-end tool delivers smooth chip evacuation and precise contouring on hardened steels, stainless alloys, and other tough materials. The AlTiN coating provides thermal resistance and extended tool life at elevated cutting speeds. A 40-degree helix angle promotes aggressive cutting action while reducing chatter. Micrograin carbide construction ensures edge integrity and dimensional consistency across long production runs. This tool is installed and used by machinists and CNC programmers in job shops, aerospace shops, and general manufacturing facilities.

This ball end mill suits 3D contouring, slotting, and profiling operations on CNC machining centers and manual mills. The extra-long configuration, with a 1.75 inch length of cut and 4.0 inch overall length, gives reach into deep pockets and cavities where standard-length tools cannot access. Right-hand cutting and right-hand flute direction make it compatible with standard CNC spindle configurations. It is a single-end tool intended for direct chuck or collet mounting with a 0.375 inch shank diameter.

Key Features

• 0.375 inch ball end diameter with four-flute spiral geometry for smooth finishing cuts
• AlTiN coating for high-heat resistance and extended tool life on hardened materials
• Micrograin solid carbide substrate for superior edge retention and rigidity
• 40-degree helix angle reduces cutting forces and minimizes chatter
• Extra-long reach: 1.75 inch length of cut, 4.0 inch overall length
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with standard collet or end mill holders accepting a 0.375 inch round shank.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Secure the 0.375 inch shank in a matched collet or end mill holder and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow the machine tool manufacturer guidelines for tool stick-out length, as excessive extension beyond the specified length of cut can reduce rigidity and accelerate tool wear.
