Osg 3111616 Ball End Mill 0.0591 in 2 Flute Solid Carbide Wxl

Product Description

The OSG 3111616 is a solid carbide ball end mill engineered for high-performance milling in demanding ferrous and hard-material applications. It carries a 1.50 mm (0.0591 inches) mill diameter, a 2-flute right-hand helical geometry, and a 30-degree helix angle that balances chip evacuation with cutting stability. The WXL physical vapor deposition (PVD) coating reduces friction and extends tool life when cutting pre-hardened and hardened steels. Ultra-fine micrograin carbide construction supports rigidity in extended-reach setups. The 0.75 mm nose radius enables precise ball-form profiling. This tool suits CNC machinists and tool-and-die professionals running finish or roughing passes on difficult materials.

The 3111616 is built for milling steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. Its extended-reach design with a 14.80 mm neck length and 1.45 mm neck diameter allows access to deep pockets and complex contours where standard-length tools cannot reach. The 4.00 mm straight-cylindrical shank fits common collet systems used in precision CNC machining centers. Single-end configuration means the tool is replaced rather than reindexed. The Series 3790 designation places it in the OSG Exocarb WXL High Performance line, which targets pre-hardened and hardened steel applications requiring consistent surface finish.

Key Features

• WXL PVD coating optimized for pre-hardened and hardened steels, stainless, and superalloys
• Ultra-fine micrograin solid carbide construction for rigidity and wear resistance
• Extended-reach geometry: 14.80 mm neck length, 1.45 mm neck diameter, 16.00 mm reach length
• 30-degree medium helix angle supports both roughing and finishing passes
• Right-hand cut, right-hand flute, straight-cylindrical shank with h6 tolerance for secure collet grip

Compatibility

Designed for use in CNC machining centers with 4.00 mm collet or end mill holder systems. Primary workpiece materials include steel, stainless steel, cast iron, and hard materials (ISO material codes P, M, K, H). Secondary workpiece materials include non-ferrous metals and superalloys and titanium (ISO codes N, S). Part of OSG Series 3790 Exocarb WXL High Performance End Mills.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom professionals. Secure the 4.00 mm shank in a clean, properly sized collet or end mill holder and torque to the holder manufacturer specification. Inspect the shank and collet bore for contamination or wear before seating. Verify spindle direction is set to right-hand rotation before engaging the cut. Do not exceed the tool manufacturer recommended depth-of-cut or feed parameters for the target workpiece hardness.
