Accupro 12184342 Ball End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 12184342 is a solid carbide ball end mill designed for precision milling of contoured surfaces, cavities, and complex 3D profiles in ferrous and non-ferrous materials. The micrograin carbide substrate provides rigidity and edge retention under demanding cutting conditions. A 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces, while the AlTiN coating adds thermal and oxidation resistance for extended tool life in dry or semi-dry machining environments. With three flutes and a right-hand cutting direction, this single-end tool delivers a balance of chip clearance and surface finish quality suitable for finish and semi-finish milling passes.

This ball end mill is suited for CNC machining centers in job shop, tooling, and die-mold applications. The 0.2031-inch diameter and 0.625-inch length of cut make it appropriate for fine detail work and tight-radius pocketing in hardened steels, stainless, cast iron, and similar materials. The 1/4-inch shank fits standard collet chucks and end mill holders commonly found on vertical and horizontal machining centers.

Key Features

• 0.2031-inch (13/64) ball nose diameter for fine contour and profile milling
• AlTiN coating for high-temperature resistance and extended tool life
• 40-degree helix angle for efficient chip evacuation and reduced cutting forces
• Micrograin solid carbide substrate for rigidity and edge durability
• Three-flute, single-end configuration with right-hand spiral flute direction
• 1/4-inch shank diameter compatible with standard collet and end mill holders

Compatibility

Designed for use in CNC machining centers with standard 1/4-inch collet chucks or end mill holders. Suitable for finish and semi-finish milling of ferrous and non-ferrous workpieces where a ball nose profile is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Seat the shank fully into the holder to the recommended gauge depth and torque the collet nut or set screw according to the toolholder manufacturer specifications. Verify runout at the tool tip before initiating a cut to avoid premature edge wear or part damage.
