Osg 8549812 Square End Mill 12mm 6 Flute Solid Carbide

Product Description

The OSG 8549812 is a 6-flute solid carbide square end mill designed for high-performance material removal in ferrous and non-ferrous machining applications. It features a 12 mm cutting diameter, a 30 mm length of cut, and a 90 mm overall length. The micrograin carbide substrate paired with a DUROREY coating delivers wear resistance and thermal stability at elevated cutting speeds. A 43-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is intended for use by machinists and CNC operators working in job shop, production, or tool room environments.

This end mill suits vertical and horizontal milling operations requiring tight tolerances and clean square shoulders. It is well matched to finishing and semi-finishing passes in steel, stainless steel, cast iron, and similar materials where coating performance is critical. The single-end, right-hand cut and right-hand flute configuration is standard for conventional CNC milling center setups. The 12 mm shank diameter matches the cutting diameter for direct collet or end mill holder installation without a reducer sleeve.

Key Features

• 6 flutes for improved surface finish and feed rate capability
• DUROREY coating for enhanced wear resistance and heat management
• 43-degree helix angle promotes effective chip evacuation
• Micrograin solid carbide substrate for rigidity and edge retention
• Center-cutting design allows plunge entry
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 12 mm shank in ER collets, end mill holders, or hydraulic chucks.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Seat the shank to the recommended gauge line depth in the holder and torque the retention mechanism to the holder manufacturer specifications. Inspect the cutting edges for chips or coating damage before each use.
