Accupro 12463880 Ball End Mill 0.12in 2 Flute Carbide

Product Description

The ACCUPRO 12463880 is a miniature solid carbide ball end mill designed for precision milling operations requiring tight tolerances and fine detail. Built from micrograin carbide, this single-end tool features a 0.12-inch cutting diameter and a 2-flute, right-hand spiral configuration with a 30-degree helix angle. The ball nose geometry allows for contoured surface milling, radius cuts, and detailed slot work in ferrous and non-ferrous materials. The bright, uncoated finish suits applications where coating interaction with the workpiece material is a concern. This tool is installed and operated by machinists and tool-and-die professionals working on CNC or manual milling machines.

This end mill is suited for light-duty material removal and finish passes in miniature or close-tolerance machining environments. The 0.36-inch length of cut (LOC) and 1.5-inch overall length (OAL) make it well-matched for shallow-cavity work, mold details, and intricate profiling where larger tools cannot reach. The 0.125-inch shank fits standard collets and end mill holders commonly used in small-diameter tooling setups. Right-hand cutting direction means it runs with standard spindle rotation on most machining centers and knee mills.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance in precision cuts
• Ball nose geometry enables contoured surface milling and radius-bottom slots
• 2-flute, right-hand spiral with 30-degree helix angle for efficient chip evacuation
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Miniature series sizing at 0.12-inch diameter for fine-detail and tight-space applications
• Single-end design for direct collet or end mill holder mounting

Compatibility

Designed as a miniature-series replacement or direct-fit ball end mill for setups using a 0.125-inch shank collet or end mill holder on standard CNC machining centers or manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist following shop-standard tool-change procedures. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully in the collet or holder to the appropriate grip depth to minimize runout and tool deflection. Verify spindle direction is set to right-hand rotation before engaging the cut, as this is a right-hand cutting tool.
