Osg 5411508 Square End Mill 0.5in 6 Flute Cobalt Ticn

Product Description

The OSG 5411508 is a 6-flute cobalt square end mill designed for high-performance milling in ferrous and hardened materials. Built from M42 cobalt high-speed steel and finished with a TiCN (Titanium Carbonitride) coating, it delivers extended tool life and thermal resistance compared to standard HSS tooling. At 0.5 inches in diameter with a 1.25-inch length of cut and 3.25-inch overall length, it fits a wide range of vertical and horizontal milling operations. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. Installed by machinists and tool-and-die professionals in CNC and manual milling setups.

The 5411508 belongs to OSG Series 541, a regular-length single-end cobalt end mill line suited for general-purpose slot milling, peripheral milling, and profiling in ferrous alloys, stainless steel, and other tough materials. The 0.5-inch shank diameter matches standard R8, ER32, and side-lock holders common in VMC and manual knee-mill setups. With a right-hand cut and right-hand spiral, it is compatible with conventional milling machine spindle rotation. This tool is appropriate for job shops, production machining environments, and maintenance departments requiring reliable, repeatable material removal.

Key Features

• 6-flute geometry increases feed rate potential and improves surface finish compared to 4-flute designs
• M42 cobalt material grade provides superior heat and wear resistance over standard M2 HSS
• TiCN coating reduces friction and extends tool life in abrasive and tough alloy applications
• 30-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting design enables direct plunge milling without a pilot hole
• Right-hand cut with single-end configuration for standard milling machine use

Compatibility

OSG Series 541 regular-length single-end cobalt square end mill. Compatible with standard 0.5-inch shank collet chucks, end mill holders, and side-lock toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the full recommended engagement depth in the holder and torque set screws or collet nuts per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to maximize tool life and surface finish quality.
