Accupro 12184559 Ball End Mill 0.0787 in 4 Flute Carbide

Product Description

The ACCUPRO 12184559 is a solid carbide ball end mill designed for precision milling operations in metal, composite, and engineering-grade materials. With a 0.0787-inch (2 mm) cutting diameter and 4-flute spiral geometry, it delivers fine surface finishes and accurate contour work in a compact form factor. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces at the tool tip. The uncoated micrograin carbide construction makes it well suited for applications where coating additives would interfere with surface finish or where re-grinding is anticipated. This is a single-end tool installed in standard CNC or manual milling machines.

This end mill is intended for small-diameter profiling, slotting, and 3D contouring passes where tight tolerances are required. The 0.315-inch (8 mm) length of cut and 3 mm shank diameter make it appropriate for use in precision toolholders on CNC machining centers, die-sinking operations, and mold work. It is typically run by machinists and toolroom operators in job shop, production, and tooling environments. The regular-length designation keeps overhang minimal, supporting rigidity at small diameters.

Key Features

• 0.0787-inch (2 mm) ball cutting diameter for fine contouring and profiling
• 4-flute spiral design improves surface finish and feed rate capability
• 40-degree helix angle for efficient chip evacuation at small diameters
• Micrograin solid carbide substrate for hardness and edge retention
• Uncoated finish suitable for re-grinding or finish-critical applications
• Single-end construction with 3 mm shank for standard toolholder compatibility

Compatibility

Designed for use in CNC machining centers and manual mills accepting a 3 mm shank diameter toolholder. Suitable for right-hand spindle rotation as a direct OEM-style replacement or new-installation end mill in standard collet chucks and precision toolholders.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout procedures for small-diameter carbide tooling. Always confirm shank engagement depth meets toolholder manufacturer minimums before operation. Inspect the cutting edges under magnification prior to use, as micrograin carbide tools are brittle and sensitive to impact. Do not use this tool in hand-held or unsupported setups.
