Accupro 12183972 Ball End Mill 0.276 in 2 Flute Carbide Ticn

Product Description

The ACCUPRO 12183972 is a single-end ball end mill designed for contour milling, profiling, and 3D surface work in machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for harder workpiece materials and tight-tolerance finishes. The mill measures 0.276 inches (7 mm) in cutting diameter with a 0.748 inch (19 mm) length of cut, a 0.315 inch (8 mm) shank diameter, and a 2.480 inch (63 mm) overall length. A TiCN coating reduces friction and improves wear resistance during operation. The 40-degree helix angle promotes efficient chip evacuation across a range of materials. This tool is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill suits CNC machining centers and manual mills running right-hand spindle rotation. It is appropriate for profiling, slotting, and contouring in ferrous and non-ferrous materials where a ball-nose geometry is required for radius features or blended surfaces. The single-end configuration and solid carbide construction make it a standard choice for finish passes on dies, molds, and precision components where edge life and dimensional accuracy matter.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• TiCN coating reduces friction and extends tool life in abrasive materials
• 40-degree right-hand helix promotes effective chip evacuation
• 2-flute ball-nose geometry suited for 3D contouring and radius features
• 0.315 inch (8 mm) shank diameter for standard collet and chuck compatibility
• Single-end design with right-hand cutting direction

Compatibility

Designed for use in CNC machining centers and milling machines with right-hand spindle rotation accepting an 8 mm shank. Suitable for standard ER collet chucks and milling chucks configured for 8 mm tooling.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank fully into the collet or chuck and torque the retention nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning the cut to protect both the tool and the workpiece.
