Accupro 12185362 Ball End Mill 0.2188 in 4 Flute Carbide

Product Description

The ACCUPRO 12185362 is a double-end ball end mill designed for precision milling operations in metalworking and machining applications. It measures 0.2188 inches in diameter with a 0.4375-inch length of cut and a 2.5-inch overall length. The tool is constructed from solid carbide and features a TiCN (Titanium Carbonitride) coating, which improves surface hardness and wear resistance for extended tool life in demanding cutting conditions. Four spiral flutes with a 40-degree helix angle promote efficient chip evacuation and smooth cutting action. This tool is installed and operated by machinists and CNC programmers working on precision parts.

This end mill is suited for milling slots, pockets, contours, and three-dimensional profiles in ferrous and non-ferrous materials. The stub-length flute geometry and 0.25-inch shank diameter make it compatible with standard collet and end mill holders. The right-hand cutting and right-hand flute direction conform to standard CNC milling setups. The double-end design allows the operator to index to the second cutting end when the first end is worn, extending the usable life of the tool before replacement.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision machining
• TiCN coating enhances hardness and extends tool life in abrasive cutting environments
• 4-flute spiral design with 40-degree helix angle for efficient chip evacuation
• Double-end configuration provides two usable cutting ends per tool
• Right-hand cut and right-hand flute direction for standard CNC milling setups
• Stub-length flute type offers added rigidity for tight-tolerance work

Compatibility

Designed for use with standard 0.25-inch collet chucks and end mill holders in CNC machining centers and manual milling machines configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and machine power is off before changing tooling. Seat the shank fully into the holder and torque the collet nut or set screw per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
