Accupro 12277148 Ball End Mill 0.023in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12277148 is a miniature solid carbide ball end mill designed for high-precision milling operations in tight-tolerance applications. With a 0.0230-inch cutting diameter and a 0.0350-inch length of cut, this tool is built for fine detail work in hardened and difficult-to-machine materials. The micrograin carbide substrate provides edge strength and wear resistance at small diameters. A 30-degree helix angle promotes efficient chip evacuation while maintaining cutting stability. This tool is intended for use by machinists, tool-and-die makers, and precision mold makers working on CNC machining centers or manual mills.

This end mill is suited for small-feature profiling, slotting, and contouring in mold cavities, medical components, and aerospace detail parts where a very small cutting radius is required. The single-end, right-hand cutting geometry is standard for conventional CNC toolpath programming. The bright/uncoated finish makes it compatible with a wide range of workpiece materials and cutting fluid types. Its 1/8-inch shank fits standard collet systems commonly found on high-speed spindles and micro-machining setups.

Key Features

• 0.0230-inch ball end cutting diameter for micro-scale milling operations
• Micrograin solid carbide construction for rigidity and edge retention at small diameters
• 4-flute geometry supports improved surface finish in finishing passes
• 30-degree helix angle aids chip flow and reduces cutting pressure
• Bright/uncoated finish suitable for use with most cutting fluids and materials
• Single-end design with right-hand cut and right-hand flute spiral

Compatibility

Designed as an OEM-style replacement or direct-use miniature ball end mill for CNC machining centers and high-speed spindles equipped with 1/8-inch collet systems.

Installation Notes

Installation should be performed by a qualified machinist following established toolholding procedures. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Seat the shank fully into the collet to the recommended engagement depth before torquing the collet nut. At this diameter, runout control is critical — inspect collet condition and use a precision toolholder to minimize deflection and premature tool wear.
