Accupro 12177612 Tapered Ball End Mill Solid Carbide 3 Flute

Product Description

The ACCUPRO 12177612 is a solid carbide tapered ball end mill designed for precision milling in metal, composites, and hardened materials. It features a 2-degree taper per side, a 1/2 inch small end diameter, and a 1/4 inch nose radius that produces smooth, accurate contoured surfaces. With 3 right-hand spiral flutes ground from micrograin carbide stock, it delivers consistent chip evacuation and edge retention across extended runs. The 30-degree helix angle balances cutting performance with lateral stability. This tool is centercutting, allowing plunge entry into workpieces without pre-drilling. It is used by machinists and CNC operators in job shops and production environments.

This tapered ball end mill is suited for 3D profiling, mold and die work, core and cavity machining, and deep-reach contouring where a standard end mill cannot maintain consistent wall contact. The 3-1/4 inch length of cut and 6 inch overall length provide access to deep pockets and angled walls in mold bases, die inserts, and aerospace components. The 3/4 inch shank diameter fits standard ER and side-lock tool holders common in CNC machining centers. The uncoated finish makes it straightforward to regrind and suitable for use in non-ferrous metals and graphite electrodes where coatings can cause adhesion issues.

Key Features

• 2-degree taper per side for angled wall profiling and draft-angle milling
• Ball end geometry with 1/4 inch nose radius for smooth 3D surface finishing
• Micrograin solid carbide construction for hardness and wear resistance
• 3 right-hand spiral flutes at 30-degree helix angle for efficient chip removal
• Centercutting design allows direct plunge entry
• Uncoated finish suitable for non-ferrous metals, graphite, and regrind applications

Compatibility

Designed for use in CNC machining centers with standard 3/4 inch shank tool holders including ER collet chucks and side-lock holders. Fits milling applications requiring a tapered reach end mill with ball end geometry.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is cleaned and free of debris before mounting. Verify runout with a dial indicator after tooling installation to confirm seating before beginning a cut. Follow machine manufacturer torque specifications for the tool holder type in use.
