The OSG 3110520 is a solid carbide ball end mill engineered for high-performance milling in demanding ferrous and hard material applications. Part of OSG's Series 3790 Exocarb WXL line, this single-end tool carries a 0.50 mm (0.0197 inch) mill diameter with a 0.40 mm length of cut and a 4.00 mm straight-cylindrical shank. The WXL PVD coating provides elevated wear resistance when cutting pre-hardened and hardened steels. With a 30-degree medium helix and ultra fine micrograin carbide substrate, it balances cutting efficiency with edge integrity during both roughing and finishing passes. Licensed machinists and CNC operators in precision machining environments are the primary users of this tool.
This end mill is suited for precision milling operations on steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. The extended reach configuration, with a 2.00 mm reach length and 0.45 mm neck diameter, allows the tool to access confined features and deep pockets without interference. It is well-matched to high-speed machining centers and CNC milling applications where tight tolerances and fine surface finishes are required on hardened workpieces.
Designed for use in CNC machining centers accepting a 4.00 mm straight-cylindrical shank (h6 tolerance). Primary workpiece materials include steel, stainless steel, cast iron, and hard materials; secondary materials include non-ferrous metals, superalloys, and titanium.
Installation and operation should be performed by qualified machinists familiar with CNC tooling setup. Confirm spindle collet or chuck bore matches the 4.00 mm shank diameter and meets h6 tolerance requirements before securing the tool. Ensure the machine is fully powered down and spindle is at rest before changing tooling. Follow the machine manufacturer's runout and tool projection specifications to maintain dimensional accuracy at this diameter.
