Osg 412-187508 Square End Mill 3/16 in 2 Flute Carbide

Product Description

The OSG 412-187508 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/16 inch cutting diameter with a 3/8 inch length of cut and a 2 inch overall length, making it well suited for tight-clearance slotting, profiling, and peripheral milling. The 30-degree helix spiral flute geometry promotes efficient chip evacuation, while the TiCN coating adds surface hardness and wear resistance for extended tool life. With two flutes and centercutting capability, this end mill handles both plunge and lateral cutting passes. It is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill is built for use in CNC machining centers and manual mills where fine detail work and tight tolerances are required. The 3/16 inch shank diameter matches the cutting diameter for straightforward collet or end mill holder setup. The micrograin solid carbide construction provides rigidity and is appropriate for ferrous and non-ferrous materials where wear resistance matters. The right-hand cut and right-hand flute configuration is standard for conventional spindle-direction setups.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• TiCN finish for increased surface hardness and extended tool life
• 30-degree helix spiral flute for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut, right-hand flute — standard spindle-direction compatible

Compatibility

Designed as a Series 412 OSG end mill for use in standard collet chucks, end mill holders, or shrink-fit tooling systems accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines. Ensure the spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify collet or holder bore matches the 3/16 inch shank diameter to ensure runout is within acceptable limits. Inspect the cutting edges for chipping or wear before each use and replace the tool if damage is observed.
