Accupro 12177607 Tapered Ball End Mill Solid Carbide

Product Description

The ACCUPRO 12177607 is a tapered ball end mill engineered for precision milling in demanding CNC and manual machining applications. Built from micrograin solid carbide, it delivers the hardness and edge retention needed for contour milling, die work, and deep-cavity profiling. The ball end geometry produces a 1/8 inch nose radius, enabling smooth 3D surface finishing. With a 2-degree taper angle per side, it maintains rigidity through long reaches while reducing deflection in deep-slot operations. Three right-hand spiral flutes with a 30-degree helix angle provide efficient chip evacuation. This tool is installed and operated by machinists and CNC tooling professionals.

This end mill is suited for mold and die machining, aerospace component finishing, and general contour work where a long reach and precise ball-nose geometry are required. The 3-1/4 inch length of cut and 6 inch overall length allow access to deep cavities and complex 3D profiles. The uncoated micrograin carbide construction makes it appropriate for a range of ferrous and non-ferrous materials where coating is not specified or where regrinding is planned.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• Ball end with 1/8 inch nose radius for smooth 3D surface finishing
• 2-degree taper angle per side for reach into deep cavities with reduced deflection
• 3 right-hand spiral flutes at 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge entry into workpiece
• Uncoated finish suitable for applications where regrinding or specific coatings are not required

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/2 inch shank diameter. Compatible with standard ER collet chucks, end mill holders, and shrink-fit toolholders sized for 1/2 inch shank tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the 1/2 inch shank is fully seated and properly torqued in the toolholder to minimize runout and prevent pullout during cutting. Verify tool projection and reach requirements before beginning a machining program. Do not exceed manufacturer-recommended cutting parameters for the workpiece material.
