Accupro 12184507 Ball End Mill 0.375 in 3 Flute Carbide

Product Description

The ACCUPRO 12184507 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in demanding machining environments. Built from micrograin solid carbide and coated with AlTiN, this tool delivers high heat resistance and wear life in harder workpiece materials. It features a 0.375-inch diameter, a 1-inch length of cut, and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. Three flutes provide a balance between chip clearance and surface finish quality. This tool is intended for use by machinists and tooling professionals in CNC milling operations.

This end mill is suited for both roughing and finishing passes in ferrous metals, hardened steels, stainless, and high-temperature alloys where AlTiN coating provides a thermal barrier at the cutting edge. The long-reach, 4-inch overall length allows access into deeper pockets and cavities. Right-hand cutting and right-hand spiral flute direction make this compatible with standard CNC vertical and horizontal machining center spindle configurations. It is a single-end tool with a 0.375-inch shank diameter for direct collet or end mill holder mounting.

Key Features

• AlTiN coating provides oxidation resistance and extended tool life in high-temperature cutting conditions
• Micrograin solid carbide substrate for superior hardness and edge retention
• 40-degree helix angle promotes aggressive chip evacuation and reduces cutting forces
• 3-flute geometry balances material removal rate with surface finish quality
• 4-inch overall length enables reach into deep pockets and complex 3D contours
• Single-end design with right-hand cut and right-hand spiral for standard CNC spindle use

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers using 3/8-inch collets or end mill holders with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder to the minimum insertion depth required for your tooling system, and torque the retention mechanism per the machine tool builder specifications. Verify runout with a dial indicator before beginning a cut.
