Cleveland C39011 Ball End Mill 0.1875 in 2 Flute Hss Tin

Product Description

The CLEVELAND C39011 is a single-end ball end mill designed for finishing operations in metal cutting applications. Manufactured from high speed steel (HSS) and coated with titanium nitride (TiN), it offers improved wear resistance and extended tool life compared to uncoated HSS tooling. The mill measures 0.1875 inches in diameter with a 0.5-inch length of cut, a 3/8-inch shank diameter, and a 2.375-inch overall length. The 2-flute, 30-degree right-hand spiral design promotes efficient chip evacuation during finishing passes on ferrous and cast iron workpieces.

This end mill is suited for finishing cuts on cast iron and steel in both manual and CNC milling applications. Its ball nose profile generates contoured and radiused surfaces, making it appropriate for die work, mold cavities, and profiling operations where a precise corner radius is required. The regular-length geometry fits standard toolholders and collet chucks used in vertical milling centers and knee mills. It is used by machinists, tool and die makers, and general machine shop professionals.

Key Features

• TiN coating increases surface hardness and reduces friction for longer tool life in HSS tooling
• 2-flute, 30-degree right-hand helix promotes chip clearance during finishing cuts
• Ball nose profile suited for contouring, profiling, and radiused surface finishing
• Single-end construction with 3/8-inch shank fits standard collet and toolholder systems
• Primary workpiece materials: cast iron and steel
• Series HG-2B regular-length geometry for general milling applications

Compatibility

Designed as a finishing end mill for use on cast iron and steel workpieces. Fits standard 3/8-inch collets and toolholders used in vertical milling centers, knee mills, and CNC machining centers.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Seat the 3/8-inch shank fully in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the cutting edges and TiN coating for chips or damage before each use, as a compromised edge will affect surface finish and dimensional accuracy. Follow shop-standard feeds and speeds for HSS ball end mills when programming or setting up the cut.
