Accupro 12177264 Ball End Mill 0.3937in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12177264 is a single-end ball end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers the rigidity and wear resistance required for aggressive cutting in ferrous and non-ferrous materials. The 10 mm (0.3937 inches) cutting diameter pairs with a 40-degree helix angle and spiral flute geometry to promote efficient chip evacuation and reduce cutting forces. An AlTiN coating extends tool life at elevated temperatures, making it well suited for dry or semi-dry high-speed machining. This tool is installed and operated by machinists and CNC programmers working in job shops, aerospace, mold-and-die, and general manufacturing environments.

The 12177264 is used in CNC machining centers and manual mills for profiling, contouring, slotting, and 3D surface work. The extended reach configuration, with a reach length of 3.268 inches and a neck diameter of 0.378 inches, allows access to deeper features and pocketed geometries where standard-reach tools cannot reach. With a 2-flute design, this end mill is appropriate for moderate to high material removal in medium-hardness steels, stainless, aluminum, and similar alloys. The right-hand cut and right-hand flute direction are standard for conventional CNC spindle setups.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• AlTiN coating provides high-temperature oxidation resistance for extended tool life in dry cutting
• 40-degree helix angle with spiral flutes for efficient chip evacuation
• Extended reach design with 3.268-inch reach length for deep-feature access
• Single-end, 2-flute configuration suited for profiling and 3D contouring
• Mill diameter tolerance of +0.0000 to -0.0025 inches for consistent dimensional accuracy

Compatibility

Designed as a standard shank ball end mill compatible with CNC machining centers and manual mills accepting a 10 mm (0.3937-inch) round shank via collet, end mill holder, or shrink-fit tooling.

Installation Notes

Installation should be performed by a qualified machinist following the tool holder manufacturer torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before loading or removing the tool. Verify shank seating depth and minimize tool overhang beyond the specified reach length to reduce deflection and chatter. Consult the machining center manufacturer guidelines and applicable shop safety procedures before operation.
