Accupro 12177667 Tapered Ball End Mill Solid Carbide

Product Description

The ACCUPRO 12177667 is a solid carbide tapered ball end mill designed for precision milling operations that require a controlled taper angle and a smooth spherical cutting tip. Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance needed for finishing and semi-finishing passes in hardened materials, mold cavities, and contoured surfaces. It runs with a 10-degree taper per side and a 3/32-inch small end diameter, providing accurate tapered wall geometry in a single pass. Three right-hand spiral flutes with a 30-degree helix angle promote chip evacuation and smooth cutting action. This end mill is installed and operated by machinists and tool-and-die professionals on CNC milling centers and manual mills.

This end mill is suited for mold and die work, 3D profiling, and finishing of tapered pockets and slots where wall angle accuracy is critical. The ball end geometry allows it to machine contoured and sculptured surfaces without leaving flat spots. With a 1-inch length of cut and a 1/2-inch shank diameter, it fits standard ER or end mill holders found in most machining centers. The uncoated finish makes it appropriate for use in a wide range of workpiece materials where coating interaction is a concern or where frequent resharpening is expected.

Key Features

• 10-degree taper per side for consistent tapered wall geometry
• Ball end shape with 3/64-inch nose radius for contoured surface finishing
• Micrograin solid carbide construction for hardness and edge retention
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Centercutting design allows plunge entry into the workpiece
• Uncoated finish suitable for applications requiring resharpening or where coatings are not preferred

Compatibility

Designed for use in standard 1/2-inch end mill holders or collet chucks on CNC machining centers and manual knee mills; no specific machine or system compatibility data was provided by the manufacturer for this part number.

Installation Notes

This tool is installed by machinists into a compatible end mill holder or collet chuck and secured to the rated torque for that holder type per the holder manufacturer specifications. Confirm shank runout with a dial indicator before beginning a cut. Ensure the spindle and work-holding are fully secured before starting the machine. Follow all shop safety protocols and machine guarding requirements during tool changes and operation.
