Accupro 12177260 Ball End Mill 0.2362 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12177260 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. It features a 0.2362 inch (6 mm) mill diameter with a 0.4724 inch (12 mm) length of cut and a 100 mm overall length. The two-flute, right-hand spiral design promotes efficient chip evacuation, while the AlTiN coating provides heat resistance and extended tool life in ferrous and high-temperature alloy materials. A 40-degree helix angle improves cutting performance at elevated feed rates. This tool is installed and used by machinists and CNC operators in production and job-shop environments.

This ball end mill is suited for 3D contouring, profiling, slotting, and finishing cuts on hardened steels, stainless steels, cast iron, and similar materials. The extended reach design, with a reach length of 2.4410 inches, makes it appropriate for deep-cavity and complex-geometry work where standard-reach tooling cannot access the workpiece. The single-end configuration is standard for CNC machining centers and manual milling machines accepting a 6 mm shank.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• AlTiN coating for high-heat and abrasion resistance in ferrous materials
• 40-degree helix angle for improved chip flow and surface finish
• Extended reach design with 2.4410 inch reach length for deep-cavity access
• Right-hand cutting and right-hand flute direction for standard CNC spindle use
• Tight mill diameter tolerance of +0.0000 to -0.0025 inches for dimensional accuracy

Compatibility

Designed for use in CNC machining centers and manual milling machines with a 6 mm collet or tool holder accepting a 6 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout specification. Secure the shank fully within the collet or end mill holder to the manufacturer-recommended engagement depth before tightening. Verify spindle runout before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. Always power down and lock out the spindle before changing tooling.
