Accupro 12184177 Ball End Mill 0.4331 in 2 Flute Carbide

Product Description

The ACCUPRO 12184177 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.4331-inch (11 mm) cutting diameter and a 2-flute, right-hand spiral configuration, this tool delivers clean material removal in a single-end geometry. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces on the workpiece. Manufactured from micrograin solid carbide, it offers the rigidity and wear resistance needed for demanding cuts. The uncoated finish makes it well suited for materials where coating buildup or heat transfer are concerns.

This ball end mill is used in CNC machining centers and manual mills for contouring, profiling, and 3D surface work. The stub-length geometry provides added rigidity, reducing chatter in shallow-to-moderate depth-of-cut scenarios. With a 0.5512-inch (14 mm) length of cut and a 12 mm shank diameter, it fits standard toolholders and collet chucks common in job shops, tool rooms, and production environments. It is appropriate for cutting ferrous and non-ferrous metals where a tight-tolerance ball-nose profile is required.

Key Features

• 0.4331-inch (11 mm) ball cutting diameter for precise radius profiling
• 2-flute, right-hand cut and right-hand flute spiral geometry
• 40-degree helix angle for efficient chip evacuation
• Micrograin solid carbide construction for rigidity and wear resistance
• Uncoated finish suitable for applications where coated tooling is not required
• Stub-length design reduces deflection and improves tool stability

Compatibility

Designed as an OEM-style single-end ball end mill for use in standard 12 mm toolholders, collet chucks, and shrink-fit holders on CNC or manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Verify that the shank is fully seated and that the toolholder is torqued to the machine manufacturer specification before running. Inspect the cutting edges for chips or wear before each use, as carbide end mills are brittle and should not be used if edge damage is present.
