Osg 3112116 Ball End Mill 0.0787 in 2 Flute Solid Carbide Wxl

Product Description

The OSG 3112116 is a solid carbide ball end mill designed for high-performance milling in demanding ferrous and hard material applications. Part of the OSG Series 3790 Exocarb WXL line, this single-end mill features a 0.0787-inch (2.00 mm) cutting diameter with a 1.60 mm length of cut and a 1.00 mm nose radius. The WXL PVD coating provides enhanced hardness and heat resistance, making this tool well suited for roughing and finishing operations in pre-hardened and hardened steels. The ultra-fine micrograin carbide substrate delivers rigidity and edge retention in difficult cutting conditions. Licensed machinists and CNC operators in tool and die, aerospace, and precision machining shops are the primary users of this end mill.

This end mill is designed for milling steel, stainless steel, cast iron, and hard materials as primary workpiece materials. Secondary workpiece materials include non-ferrous metals, superalloys, and titanium. The extended-reach geometry, with a 16.00 mm reach length and a 14.40 mm neck length at a reduced 1.95 mm neck diameter, allows access in deep pockets and tight contours where standard-length tools cannot reach. The 4.00 mm straight-cylindrical shank with h6 tolerance fits standard collet and end mill holders commonly used in CNC machining centers.

Key Features

• WXL PVD coating for elevated hardness and thermal resistance in hardened steel milling
• Ultra-fine micrograin solid carbide substrate for superior edge retention and rigidity
• Extended-reach design with 16.00 mm reach length and reduced 1.95 mm neck diameter for deep-pocket access
• 2-flute, 30-degree medium helix geometry supports both roughing and finishing in a single tool
• Right-hand cut and right-hand flute direction with helical flute type
• Single-end configuration; no coolant-through, no chipbreaker, no variable helix or variable index

Compatibility

Rated for primary workpiece materials including steel, stainless steel, cast iron, and hard materials (ISO material codes P, M, K, H); compatible with secondary workpiece materials including non-ferrous metals and superalloys and titanium (ISO codes N, S). Fits standard 4.00 mm collet or end mill holders with h6 shank tolerance.

Installation Notes

Installation and operation of this end mill should be performed by qualified machinists familiar with CNC milling equipment and cutting tool safety. Ensure the spindle is fully stopped and locked out before mounting or removing the tool from the holder. Use a properly sized collet or end mill holder matched to the 4.00 mm shank diameter to maintain runout accuracy and prevent tool pullout. Follow machine manufacturer guidelines and applicable shop safety standards for speeds, feeds, and depth of cut when programming tool paths in hardened or hard material applications.
