Accupro 12184058 Ball End Mill 7/8 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12184058 is a single-end ball end mill designed for milling contoured surfaces, cavities, and complex 3D profiles in a wide range of materials. The tool measures 0.875 inches in diameter with a 1.75-inch length of cut and a 4-inch overall length. Constructed from micrograin solid carbide, it delivers the rigidity and edge retention needed for demanding CNC milling operations. The 2-flute configuration supports efficient chip evacuation, and the 40-degree right-hand spiral helix provides aggressive shear action while reducing cutting forces. The bright, uncoated finish makes it well suited for applications where coating interaction with workpiece material is a concern.

This end mill is used in vertical and horizontal machining centers for profiling, contouring, slotting, and finishing operations. The ball nose geometry generates smooth curved surfaces and is common in mold and die work, aerospace components, and general precision machining. The 7/8-inch shank diameter matches the mill diameter, allowing direct mounting in standard collet chucks or end mill holders. It is a right-hand cutting tool intended for conventional CNC setups operated by machinists and tool-and-die professionals.

Key Features

• Micrograin solid carbide construction for superior hardness and edge retention
• 40-degree right-hand helix reduces cutting forces and improves surface finish
• Ball nose geometry for contouring, profiling, and 3D surface milling
• 2-flute design promotes chip evacuation in slotting and pocket milling
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Single-end design with matched 7/8-inch mill and shank diameter

Compatibility

Designed as a direct-mount single-end ball end mill for use in CNC machining centers equipped with standard collet chucks or end mill holders accepting a 7/8-inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for tool holding and runout tolerances. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Verify collet or holder cleanliness and confirm proper seating depth to maintain the stated shank diameter tolerance of -0.0001 to -0.0004 inches. Do not exceed the tool's rated length of cut when programming axial depth of cut parameters.
