Accupro 12179243 Ball End Mill 0.75in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12179243 is a solid carbide ball end mill designed for high-performance milling in demanding machining environments. With a 0.75 inch mill diameter and a 1.5 inch length of cut, this tool handles contouring, profiling, and 3D surface work on hardened steels, stainless alloys, and high-temp materials. The four-flute, right-hand spiral geometry provides efficient chip evacuation and smooth surface finishes. The nACRo coating delivers high hardness and oxidation resistance, making it well suited for dry or near-dry cutting conditions. Micrograin carbide construction ensures edge integrity and longer tool life under aggressive feeds and speeds.

This end mill is intended for use in CNC machining centers, vertical mills, and high-speed machining applications across job shops, tool and die operations, and precision manufacturing facilities. It is engineered for right-hand cutting with a 40-degree helix angle that improves chip flow and reduces cutting forces on the workpiece. The single-end configuration and 4 inch overall length provide adequate reach for most standard milling setups without sacrificing rigidity.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• nACRo coating for high oxidation resistance and performance in dry or near-dry cutting
• 40-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Four right-hand spiral flutes for smooth finish on contoured and profiled surfaces
• Mill diameter tolerance of +0.000 to -0.002 inches for precise fitment
• Single-end design with 0.75 inch shank diameter for secure toolholder engagement

Compatibility

Designed for use in standard CNC toolholders and collet chucks accepting a 0.75 inch shank diameter. Suitable for milling hardened steels, stainless steels, and high-temperature alloys where a ball end mill profile is required.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the toolholder bore and collet are clean and free of debris before seating the shank. Confirm runout is within tolerance before initiating a cutting program. Follow machine manufacturer guidelines and applicable shop safety protocols when loading or unloading rotating cutting tools.
