Accupro 12185352 Ball End Mill 0.1875 in 4 Flute Carbide

Product Description

The ACCUPRO 12185352 is a solid carbide ball end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.1875-inch (3/16-inch) diameter and a 40-degree helix angle, this tool delivers smooth chip evacuation and reduced cutting forces in tight-tolerance work. The four-flute, double-end configuration extends tool life by providing a second usable end when the first wears. At 2.0 inches overall length with a 0.375-inch length of cut, it suits compact machining envelopes. Right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. Licensed machinists and toolroom technicians are the primary installers and operators.

This end mill is suited for CNC machining centers, manual knee mills, and toolroom applications requiring small-diameter ball-nose profiling. Typical applications include 3D contouring, slot milling, and finishing passes in mold work, die cavities, and aerospace components. The stub length type keeps deflection low when working in shallow pockets with small-diameter tooling. The uncoated carbide substrate performs well in aluminum, brass, plastics, and softer steels where coating adhesion is less critical or where re-sharpening is anticipated.

Key Features

• Double-end design provides two cutting ends, extending tool value per unit
• 40-degree helix angle promotes efficient chip flow and reduced heat buildup
• Solid carbide construction offers superior rigidity and wear resistance over HSS alternatives
• Four flutes deliver a fine surface finish on finishing passes
• Right-hand cut and right-hand spiral match standard CNC spindle configurations
• Stub length type minimizes deflection in small-diameter, shallow-reach applications

Compatibility

Designed as an OEM-style replacement or direct tooling option for CNC machining centers and manual mills accepting a 3/16-inch round shank end mill.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a calibrated tool holder and collet sized for a 3/16-inch shank to prevent runout. Verify tool projection and length of cut clearance before initiating a new program to avoid tool breakage on first pass.
