Osg 8549875 Corner Radius End Mill 6mm 6 Flute Carbide

Product Description

The OSG 8549875 is a solid carbide corner radius end mill engineered for finishing operations in steel and hard materials. It features a 6 mm cutting diameter, a 0.5 mm corner radius, and six right-hand helical flutes with a close pitch configuration. The tool carries a Duarise PVD coating, which improves wear resistance and thermal stability during high-speed cuts. With a 15 mm length of cut and a 60 mm overall length, it is sized for standard toolholder setups requiring a straight-cylindrical shank. Machinists and tool-and-die professionals working on ferrous alloys and hardened steels will find this a direct production-ready option.

This end mill is intended for finishing passes on steel and hard material workpieces in CNC milling applications. The center-cutting geometry allows plunge entry, and the single-end design is suited for precision contouring and profiling where corner blend radius control is critical. It is compatible with standard straight-shank toolholders accepting a 6 mm shank diameter. The 43-degree helix angle promotes chip evacuation and surface finish quality on close-tolerance features.

Key Features

• 6 mm cutting diameter with 0.5 mm corner radius and tolerance of 0.00 to -0.02 mm
• Six right-hand helical flutes with close pitch for finishing applications
• Duarise PVD coating for wear resistance in steel and hard material cutting
• Center-cutting capable with right-hand cutting direction
• Straight-cylindrical 6 mm shank with h4 shank diameter tolerance
• No coolant-through design; suitable for external coolant or dry cutting setups

Compatibility

Designed for use with standard straight-shank toolholders accepting a 6 mm shank diameter. Primary workpiece material compatibility is steel and hard material (material codes P and H).

Installation Notes

Installation should be performed by a qualified machinist following standard CNC tooling setup procedures. Ensure the spindle is fully powered down and the machine is in a safe state before loading or unloading the tool. Seat the shank fully in the toolholder collet and torque the retention mechanism to the toolholder manufacturer specification. Confirm runout is within tolerance before beginning a cut, particularly for finishing operations where corner radius accuracy is critical.
