Osg 412-187511 Square End Mill 3/16 in 2 Flute Solid Carbide

Product Description

The OSG 412-187511 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in machining centers and CNC mills. It features a 3/16 inch cutting diameter, a 3/8 inch length of cut, and a 2 inch overall length with a matching 3/16 inch shank diameter. The TiAlN coating improves heat resistance and extends tool life in high-speed cutting applications. A 30-degree spiral flute geometry promotes efficient chip evacuation and smooth cutting action. This tool is used by machinists and tooling professionals in production and job shop environments.

The 412-187511 is suited for slotting, profiling, and peripheral milling operations. Its centercutting capability allows plunge entry directly into the workpiece without a pre-drilled hole. Right-hand cut and right-hand flute orientation make it compatible with standard CNC spindle setups. The two-flute design is particularly effective in softer materials and applications where chip clearance is a priority. This end mill belongs to OSG Series 412 and is manufactured from micrograin carbide for consistent edge integrity at tight tolerances.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiAlN finish for improved thermal resistance in high-speed cuts
• Centercutting design allows direct plunge milling
• 30-degree helix angle promotes smooth chip flow and reduced cutting forces
• Right-hand cut and right-hand spiral flute for standard CNC compatibility
• Two-flute geometry maximizes chip clearance in softer workpiece materials

Compatibility

Designed as a direct-fit tooling solution for standard 3/16 inch collets and tool holders used in CNC machining centers and manual milling machines. Specific model compatibility was not provided in the available product data.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout tolerances. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing or seating the end mill. Use a calibrated collet or end mill holder rated for the 3/16 inch shank diameter to minimize runout. Confirm cutting direction settings on the machine controller match the right-hand cut orientation of this tool before beginning any operation.
