Accupro 12185383 Ball End Mill 0.5in 4 Flute Solid Carbide Ticn

Product Description

The ACCUPRO 12185383 is a double-end, solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles. It carries a 0.5-inch mill diameter with a 0.625-inch length of cut and a 40-degree helix angle that promotes efficient chip evacuation and smooth cutting action. A TiCN (titanium carbonitride) coating adds surface hardness and heat resistance, extending tool life in ferrous and non-ferrous materials alike. With four flutes in a right-hand spiral configuration, the tool delivers a balance of chip clearance and surface finish quality. Machinists and CNC operators working in job shops and production environments will find this geometry well-suited to finish and semi-finish milling passes.

This end mill is built for use in vertical machining centers, CNC knee mills, and similar equipment where tight tolerances on contoured workpieces are required. The double-end configuration provides two usable cutting ends, making it a practical choice for shops looking to extend tool value without sacrificing geometry. Typical applications include die and mold work, aerospace components, and precision part runs in steel, stainless, cast iron, and high-temperature alloys where a TiCN coating provides a meaningful performance advantage.

Key Features

• Double-end design provides two cutting ends per tool, extending usable tool life
• TiCN coating increases surface hardness and thermal resistance for longer run times in ferrous materials
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Four right-hand spiral flutes balance material removal rate with surface finish quality
• Solid carbide construction delivers rigidity and wear resistance superior to high-speed steel alternatives
• Stub length classification suits short-reach setups where rigidity is critical

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 0.5-inch straight shank end mill holder or collet.

Installation Notes

Installation of end mills should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked before changing tooling. Seat the shank fully into the holder or collet to the minimum clamping depth recommended by the holder manufacturer to prevent pullout during cutting. Verify runout with a dial indicator after clamping before initiating any cutting program.
