Osg 36900911 Ball End Mill 0.0938 in 2 Flute Solid Carbide

Product Description

The OSG 36900911 is a solid carbide ball end mill from the OSG Series 3690 ExocarbWXL line, designed for high-performance milling in hard and demanding materials. It features a 0.0938 inch mill diameter, a 0.0938 inch length of cut, and a 2.5 inch overall length with a 0.25 inch straight-cylindrical shank. The WXL PVD coating is applied over an ultra-fine micrograin carbide substrate, making this end mill well suited for rigidity-critical applications across a wide variety of materials and milling operations, including both roughing and finishing passes. A licensed machinist or CNC tooling specialist typically selects and installs this tool.

This end mill is designed for milling steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium. The extended-reach geometry and reduced neck diameter of 0.0920 inches allow access to deep pockets and confined features while maintaining rigidity. The single-end, right-hand cutting configuration is standard for CNC vertical machining centers and manual knee mills where precision profiling and contouring are required.

Key Features

• WXL PVD coating on ultra-fine micrograin solid carbide substrate for hard milling performance
• 0.0938 inch ball nose diameter with 0.0469 inch nose radius for accurate profiling
• Extended reach design with 0.4688 inch reach length and 0.375 inch neck length
• 30-degree medium helix angle for balanced chip evacuation and cutting stability
• Right-hand cut and right-hand flute direction, single-end configuration
• Rated for roughing and finishing operations across ferrous and non-ferrous materials

Compatibility

Designed for use in CNC machining applications involving steel, stainless steel, cast iron, hard materials, non-ferrous metals, superalloys, and titanium, as specified by OSG for the Series 3690 ExocarbWXL line. Compatible with standard 0.25 inch straight-shank tool holders with h6 shank diameter tolerance.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Use a torque-rated collet or end mill holder appropriate for a 0.25 inch straight-cylindrical shank. Verify runout with a dial indicator after tool installation to protect the small-diameter carbide from premature fracture.
