Cleveland C39027 Ball End Mill 0.125 in 2 Flute Hss Ticn

Product Description

The CLEVELAND C39027 is a single-end ball end mill designed for finishing operations in ferrous and cast iron workpiece materials. Built from high speed steel (HSS) with a TiCN (Titanium Carbonitride) coating, it delivers improved hardness and wear resistance compared to uncoated HSS tooling. The 0.125-inch mill diameter and 0.375-inch length of cut make it well suited for contouring, profiling, and detail work in tight geometries. The 30-degree helix angle promotes smooth chip evacuation during cutting. This end mill is intended for use by machinists and tooling professionals working on CNC mills, manual vertical mills, and similar machine tool setups.

This end mill is appropriate for finishing passes on cast iron and steel in both job shop and production environments. The 2-flute configuration suits slotting and profiling where chip clearance is a priority. Its regular-length design and 0.375-inch shank diameter allow direct mounting in standard collet chucks and end mill holders without extension. The HG-2B series designation identifies it within the CLEVELAND high-performance HSS ball end mill family.

Key Features

• TiCN coating increases surface hardness and extends tool life on steel and cast iron
• 30-degree right-hand spiral helix promotes efficient chip flow during finishing cuts
• 2-flute geometry provides adequate chip clearance for slotting and profiling passes
• Single-end construction with a 0.375-inch shank for direct mounting in standard holders
• Right-hand cutting direction compatible with conventional CNC and manual mill spindles
• Regular-length OAL supports rigidity and minimizes deflection in typical setups

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for applications requiring a 0.125-inch diameter ball end mill with a 0.375-inch shank in standard collet or end mill holder systems. Primary workpiece materials listed by the manufacturer are cast iron and steel.

Installation Notes

Installation and use of this end mill should be performed by qualified machinists familiar with machine tool operation and cutting tool safety. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from its holder. Verify collet size and holder bore match the 0.375-inch shank diameter before tightening. Follow shop-standard speeds and feeds for HSS tooling on the specific workpiece material to avoid tool breakage or workpiece damage.
