Accupro 12184328 Ball End Mill 0.1406 in 3 Flute Carbide

Product Description

The ACCUPRO 12184328 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and 3D profiles in ferrous and non-ferrous materials. With a 0.1406-inch cutting diameter and a 0.5-inch length of cut, this tool handles detail work in tight geometries where larger end mills cannot reach. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces, making it well-suited for both roughing passes and fine finishing in harder materials. The micrograin carbide substrate provides rigidity and edge retention without a coating, keeping the tool profile sharp for close-tolerance work in machining centers and manual mills.

This end mill is used in CNC machining centers, die and mold work, aerospace component machining, and precision prototype fabrication. Its 3-flute geometry balances chip clearance with surface finish quality, making it a practical choice for profiling, ramping, and helical interpolation in aluminum alloys, steel, and hardened materials. The single-end configuration and 3/16-inch shank are compatible with standard collet chucks and end mill holders found in most shop environments.

Key Features

• 0.1406-inch ball nose diameter for precise contouring and radius work
• 3-flute design balances chip evacuation with improved surface finish
• 40-degree right-hand helix for efficient chip flow and reduced deflection
• Micrograin solid carbide substrate for edge retention in hard and abrasive materials
• Uncoated finish suitable for applications where coating buildup is a concern
• Single-end, right-hand cut geometry compatible with standard toolholders

Compatibility

Designed for use with standard collet systems and end mill holders accepting a 3/16-inch shank diameter. Suitable for CNC machining centers and manual mills equipped for solid carbide tooling in precision milling applications.

Installation Notes

Installation should be performed by a qualified machinist following standard toolsetting procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the recommended gauge-line depth in the collet or holder to minimize runout and prevent pullout under cutting loads. Verify tool runout with a dial indicator before beginning a production cut, particularly at this diameter where deflection tolerances are tight.
