Accupro 14881977 Ball End Mill 5/64 in 3 Flute Carbide

Product Description

The ACCUPRO 14881977 is a solid carbide ball end mill designed for precision milling of small features in metalworking and machining applications. Built to miniature series specifications, it carries a 5/64 inch (0.0781 inch decimal) ball nose diameter and a 1/8 inch shank diameter, making it suited for tight-tolerance work in confined areas. The three-flute, right-hand spiral geometry with a 30-degree helix angle promotes efficient chip evacuation while maintaining cut quality in harder workpiece materials. Micrograin carbide construction provides the rigidity and wear resistance required for demanding cuts at small diameters. This is a single-end tool with a bright, uncoated finish.

This end mill is used in CNC machining centers and manual mills where small-radius contours, slots, or 3D profiling are required. The extended reach design and 0.1170 inch length of cut make it appropriate for light profiling and finishing passes in mold work, die work, and precision component manufacturing. The 0.2340 inch neck length provides additional clearance when working in recessed areas. Machinists and tool-and-die professionals working in job shops, production facilities, and tool rooms are the primary users of this tool.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance at small diameters
• Ball nose geometry produces accurate small-radius contours and 3D surface profiles
• Three right-hand spiral flutes with 30-degree helix angle for efficient chip removal
• Extended reach with 0.2340 inch neck length for access to recessed features
• Bright uncoated finish suitable for a range of workpiece materials without coating compatibility concerns
• Single-end tool in the miniature series, sized for precision small-feature work

Compatibility

Designed as an OEM-style miniature ball end mill for use in standard CNC and manual milling machines accepting a 1/8 inch shank diameter collet or tool holder.

Installation Notes

Installation is performed by qualified machinists following standard tooling procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing the tool from the collet or chuck. Verify collet size matches the 1/8 inch shank diameter and that the tool is seated to the correct gauge length before tightening. At small diameters, runout control is critical — inspect the holder and collet for wear before use.
