Accupro 14881922 Ball End Mill 3/32 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 14881922 is a solid carbide ball end mill designed for precision milling in tight spaces and miniature-scale applications. Built from micrograin solid carbide, it offers the hardness and wear resistance needed for cutting ferrous and non-ferrous metals, hardened steels, and engineering plastics. The 3/32-inch cutting diameter pairs with a 3-flute spiral geometry and a 30-degree right-hand helix angle to balance chip evacuation and surface finish in small-bore, contour, and profiling cuts. This is a single-end tool with a bright/uncoated finish, meaning it ships ready to run without a coating that could affect dimensional tolerances at this scale.

This end mill is suited for CNC machining centers and manual mills where miniature toolpaths, die work, mold cavities, or fine detail features demand a small-diameter, high-rigidity cutting tool. The extended reach design, with a 3/4-inch neck length, allows access to recessed features without sacrificing tool stability. It fits into a 1/8-inch collet or toolholder and is appropriate for prototype shops, tool-and-die operations, and production environments running small-scale precision components. A licensed machinist or CNC programmer will typically select this tool for finishing passes or detail work where a larger diameter cannot reach.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 3-flute spiral geometry with 30-degree right-hand helix for balanced chip flow and surface finish
• Extended reach with 3/4-inch neck length for access to deep or recessed features
• Bright/uncoated finish maintains tight tolerances critical at 3/32-inch scale
• Single-end configuration with right-hand cutting direction
• Miniature series sizing fits 1/8-inch shank toolholders and collets

Compatibility

Designed as a miniature-series replacement or direct-use ball end mill for CNC machining centers and manual mills equipped with 1/8-inch collets or toolholders.

Installation Notes

Installation of this end mill is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8-inch shank fully into the collet or toolholder and torque to the toolholder specification before running. At this diameter, tool runout is critical — verify runout with a dial indicator before beginning a cut to avoid premature tool breakage.
