Accupro 15024085 Ball End Mill 0.0850 in 2 Flute Carbide

Product Description

The ACCUPRO 15024085 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles in metalworking and machining applications. It measures 0.0850 inches in diameter with a 1/8-inch shank and a 1.5-inch overall length, making it well suited for tight-tolerance work in small or restricted spaces. The two-flute geometry with a 30-degree right-hand helix promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and edge retention beyond standard carbide grades. A bright, uncoated finish is retained for use on non-ferrous metals, plastics, and other materials where coating interaction is a concern. This tool is installed and run by machinists and CNC operators in job shop and production environments.

This miniature ball end mill is used in CNC machining centers and manual mills for fine detail work including die and mold cavities, engraving paths, and small-radius profiling operations. The extended-reach geometry, with a 0.5000-inch neck length, allows access to features in deeper pockets without requiring tool changes or specialized holders. It is appropriate for residential and commercial toolroom settings as well as production CNC environments where small-diameter, high-precision tooling is required.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention
• 0.0850-inch cutting diameter with a 0.2550-inch length of cut for fine detail passes
• 30-degree right-hand spiral helix promotes clean chip evacuation
• 0.5000-inch neck length provides extended reach into deep pockets
• Bright, uncoated finish suitable for non-ferrous metals and plastics
• Single-end design with 1/8-inch straight shank for standard collet compatibility

Compatibility

Designed as a miniature-series OEM-style ball end mill compatible with standard 1/8-inch collets and tool holders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the collet. Verify collet size matches the 1/8-inch shank diameter and that the collet is clean and free of debris before tightening. Follow machine manufacturer torque and runout specifications for collet nut tightening to avoid tool deflection or pull-out during operation.
