Accupro 14797433 Ball End Mill 3/64 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 14797433 is a miniature single-end ball end mill designed for precision milling in tight geometries and small-feature work. Built from solid carbide micrograin material, it delivers the rigidity and edge retention needed for accurate profiling, contouring, and slotting in hardened and abrasive workpiece materials. The cutting diameter is 0.0469 inches (3/64 inches) with a length of cut of 0.0700 inches and a 2-flute spiral configuration at a 30-degree helix angle. The bright/uncoated finish makes it well suited for non-ferrous metals, plastics, and composites where coating adhesion or heat buildup is not the primary concern. Machinists and toolroom operators working on mold cavities, prototype components, and precision fixtures will find this tool appropriate for detailed finish passes and fine feature generation.

This end mill is intended for CNC machining centers, high-speed spindles, and manual mills capable of holding tolerances at the miniature scale. The 1/8-inch shank diameter fits standard collet systems and tool holders commonly found in small-part machining environments. Right-hand cutting and right-hand flute direction make it compatible with conventional CNC spindle rotation. Its miniature series designation indicates suitability for micro-milling applications where standard end mills are too large to access features or maintain positional accuracy.

Key Features

• Solid carbide micrograin construction for edge stability in precision milling
• 0.0469 inch (3/64 inch) ball nose diameter for small-radius profiling and contouring
• 30-degree helix angle promotes smooth chip evacuation in short-length-of-cut applications
• 2-flute geometry balances chip clearance with cutting edge strength at miniature scale
• Bright/uncoated finish compatible with non-ferrous metals, plastics, and composites
• Single-end design with consistent mill diameter tolerance of +0.0000 / -0.0010 inches

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC machining centers and high-speed spindle systems accepting a 1/8-inch shank diameter with standard collet or end mill holder tooling.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Verify runout at the collet before beginning a cut, as concentricity errors are amplified at miniature diameters. Follow the machine tool manufacturer's recommended feeds, speeds, and clamping torque specifications for 1/8-inch shank tooling.
