Accupro 12177582 Tapered Ball End Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12177582 is a solid carbide tapered ball end mill designed for precision milling of contoured surfaces, complex 3D profiles, and tapered cavity work. It features a 3/8 inch small end diameter with a 1 degree taper per side and a 3/16 inch nose radius, producing smooth, accurate ball-end profiles in a single pass. The 3-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation and stable cutting at higher feed rates. Manufactured from micrograin solid carbide, it delivers the rigidity and wear resistance required for demanding CNC machining operations. This tool is uncoated and suited for use in a range of ferrous and non-ferrous materials.

This tapered ball end mill is used in CNC machining centers for die and mold work, aerospace components, and precision part finishing where tapered wall geometry is required. The 2-1/4 inch length of cut allows access into deeper pockets and cavities. The 1/2 inch shank diameter provides rigid tool holding in standard ER collet chucks, side-lock holders, or shrink-fit tooling. It is centercutting, allowing plunge entry without a pre-drilled hole. Machinists and tooling specialists in job shops, mold shops, and production environments are the primary users.

Key Features

• 1 degree taper per side for precise tapered wall geometry
• Ball end with 3/16 inch nose radius for smooth 3D surface finishing
• 3-flute right-hand spiral design with 30-degree helix for efficient chip flow
• Micrograin solid carbide construction for rigidity and extended tool life
• Centercutting capability allows direct plunge entry
• Uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed for use in CNC machining centers with standard 1/2 inch tool holders, including ER collet chucks, shrink-fit holders, and side-lock holders compatible with 1/2 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm runout with a dial indicator after clamping to avoid premature tool wear or chatter. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting cutting parameters.
