Cleveland C39152 Ball End Mill 0.4375 in 2 Flute Hss Tin

Product Description

The CLEVELAND C39152 is a double-end ball end mill designed for finishing operations in metalworking and machining applications. Built from high speed steel and coated with titanium nitride (TiN) for extended tool life, this end mill measures 0.4375 inches in diameter with a 0.8125-inch length of cut and a 4.125-inch overall length. The 2-flute, right-hand spiral configuration at a 30-degree helix angle promotes efficient chip evacuation during contouring and profiling passes. Installed by machinists and tool-and-die professionals, the C39152 is a reliable choice for precision finishing on a range of ferrous and non-ferrous workpieces.

This end mill is suited for finishing cuts on cast iron, non-ferrous metals, and steel. The double-end design offers two usable cutting ends, extending the service life of each tool before replacement is needed. The 0.5-inch shank diameter fits standard collet and end mill holders commonly found in vertical machining centers and manual knee mills. Its regular length classification makes it appropriate for general-purpose setups where extended reach is not required.

Key Features

• TiN coating increases surface hardness and reduces friction for longer cutting life
• Double-end design provides two cutting ends per tool
• 30-degree helix angle promotes smooth chip flow during finishing passes
• Right-hand cut and right-hand flute spiral for standard machining setups
• High speed steel construction suitable for cast iron, non-ferrous metals, and steel
• Series HD-2B designation for consistent tooling library management

Compatibility

Designed as a finishing end mill compatible with standard 0.5-inch collet and end mill holder systems used in vertical machining centers, knee mills, and CNC milling setups. Primary workpiece materials include cast iron, non-ferrous metals, and steel.

Installation Notes

Installation should be performed by a qualified machinist with the spindle at a complete stop and the machine in a locked-out, de-energized state before tool changes. Verify that the collet or end mill holder is clean and undamaged before seating the shank. Torque the retention mechanism according to the machine tool manufacturer's specifications. Confirm runout with a dial indicator before beginning a finishing pass to avoid dimensional error or premature tool wear.
