Accupro 12177748 Ball End Mill 0.3438 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 12177748 is a double-end ball end mill designed for precision milling operations in metal, composite, and hard material applications. Built from solid carbide, it offers the rigidity and wear resistance required for demanding cutting environments. The tool measures 0.3438 inches in diameter with a 0.75-inch length of cut and a 3.5-inch overall length. A 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. With four spiral flutes and a right-hand cutting direction, this end mill is suited for finishing and semi-finishing passes where surface quality and dimensional accuracy matter. It is installed and used by machinists and tool-and-die professionals in CNC and manual milling setups.

This ball end mill is appropriate for a wide range of milling applications including 3D contouring, profiling, slotting, and cavity work. The double-end configuration extends tool life by providing two usable cutting ends, making it a cost-effective choice for high-cycle production environments. The 3/8-inch shank diameter is compatible with standard collet and end mill holder systems commonly found in both vertical and horizontal milling machines. The bright, uncoated finish makes it well suited for use with cutting fluids in ferrous and non-ferrous material applications.

Key Features

• Solid carbide construction for high rigidity and extended tool life in demanding cuts
• Double-end design provides two cutting ends, reducing per-cut tooling cost
• 40-degree helix angle supports efficient chip evacuation and reduced cutting forces
• Four spiral flutes for improved surface finish on finishing and semi-finishing passes
• Right-hand cut and right-hand flute orientation for standard CNC and manual mill setups
• Bright uncoated finish compatible with a broad range of cutting fluid chemistries

Compatibility

Designed for use with standard 3/8-inch collets and end mill holders on CNC machining centers and manual vertical mills. No specific model compatibility was provided by the manufacturer for this part number.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and in a locked-out state per applicable shop safety procedures. Ensure the collet or tool holder is clean and free of debris before seating the shank to the specified engagement depth. Verify runout with a dial indicator after installation before beginning a cut. Do not exceed the rated length of cut or apply side loads beyond the tool geometry recommendations for this diameter class.
