Accupro 14883984 Ball End Mill 0.1181 in 4 Flute Carbide

Product Description

The ACCUPRO 14883984 is a single-end ball end mill designed for precision milling operations requiring tight tolerances and a spherical cutting profile. Built from micrograin solid carbide, this tool delivers the hardness and rigidity needed for cutting ferrous and non-ferrous materials at elevated speeds. It runs a 0.1181-inch cutting diameter with a 0.3550-inch length of cut and a 30-degree right-hand helix, which promotes chip evacuation and smooth surface finishes in small-diameter work. The bright, uncoated finish makes it well suited for applications where coating buildup or heat sensitivity is a concern.

This end mill is sized for fine detail work and tight-tolerance contouring in mold making, die work, engraving, and precision machining of small components. The miniature series classification indicates it is intended for small-diameter, high-precision applications on CNC machining centers, milling machines, and high-speed spindles. The 1/8-inch shank diameter fits standard collets used in precision toolholding systems. The 4-flute configuration provides a balance of chip clearance and edge support suitable for finishing passes in ferrous and non-ferrous stock.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance in precision cuts
• 0.1181-inch ball end diameter with mill diameter tolerance of +0.0000 / -0.0010 inches for controlled fitment
• 30-degree right-hand helix with right-hand cutting direction for efficient chip flow
• 4-flute spiral geometry balances chip clearance with surface finish quality
• Bright, uncoated finish — no coating interaction with sensitive workpiece materials
• Single-end, non-extended-reach design for maximum rigidity in short-reach setups

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 1/8-inch collet systems used in CNC milling and high-speed machining applications requiring miniature-series ball end mills.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before mounting or removing the tool. Seat the shank fully and uniformly in a matched collet to the shank diameter tolerance of -0.0001 / -0.0003 inches; improper collet fit can cause runout and premature tool failure. Verify spindle speed and feed rate are appropriate for the 0.1181-inch diameter before engaging the cut.
