Osg 8549720 Square End Mill 2mm 4 Flute Solid Carbide

Product Description

The OSG 8549720 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 2 mm cutting diameter and a 4-flute geometry, it delivers clean, accurate cuts in ferrous and non-ferrous materials. The 43-degree helix angle promotes efficient chip evacuation and reduces heat buildup during extended cuts. DUROREY coating adds surface hardness and wear resistance, extending tool life in demanding operations. This end mill features a 6 mm shank diameter and a 60 mm overall length, making it suitable for use in CNC machining centers and manual milling machines where close-tolerance work is required.

This end mill is suited for precision slot milling, profiling, and contouring operations in machine shops, tool rooms, and production environments. Its centercutting capability allows direct plunge entry into the workpiece. The right-hand cutting and right-hand flute direction are standard for conventional CNC and manual milling setups. The micrograin carbide substrate makes it a reliable choice for high-speed passes in steel, aluminum, and similar materials where dimensional accuracy is critical.

Key Features

• 2 mm cutting diameter with 5 mm length of cut for precise, shallow-slot operations
• 4-flute design provides improved surface finish compared to 2-flute alternatives
• 43-degree helix angle promotes aggressive chip evacuation and reduced cutting force
• DUROREY coating enhances hardness and wear resistance for extended tool life
• Centercutting geometry allows plunge milling without a pre-drilled pilot hole
• Micrograin solid carbide substrate delivers consistent performance in tight-tolerance work

Compatibility

Designed as a standard solid carbide square end mill with a 6 mm shank diameter, compatible with ER collet systems and end mill holders sized for 6 mm shank tooling commonly used in CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder torqued to the machine manufacturer's specifications to prevent tool pullout. Verify runout with a dial indicator after seating to maintain dimensional accuracy and protect the cutting edge.
