Osg 37700010 Corner Radius End Mill 3mm 2 Flute Carbide

Product Description

The OSG 37700010 is a solid carbide corner radius end mill designed for high-performance milling across a broad range of workpiece materials. Built to a 3 mm diameter with a 0.2 mm corner radius and 2 helical flutes, it delivers a controlled cutting profile that reduces edge chipping and extends tool life in demanding applications. The 8 mm length of cut and 60 mm overall length suit it for reaching into slots, pockets, and profiled features in precision components. A WXL physical vapor deposition (PVD) coating enhances surface hardness and heat resistance. Center-cutting geometry allows plunge entry without a pre-drilled pilot hole. This tool is installed and operated by machinists and CNC programmers in production and job-shop environments.

This end mill is suited for roughing operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The coarse pitch flute geometry promotes chip evacuation during aggressive material removal. Its right-hand cut and right-hand flute direction are compatible with standard CNC machining centers and manual vertical mills. The 6 mm straight-cylindrical shank seats in a standard toolholder or collet chuck. It is a single-end tool in the OSG Series 3770 line, intended for applications where a tight corner radius and durable carbide substrate are required.

Key Features

• 3 mm diameter with 0.2 mm corner radius for precise edge blending and reduced stress concentrations
• Solid carbide substrate for rigidity and wear resistance in hard and abrasive materials
• WXL PVD coating improves hardness and thermal stability during dry or minimal-coolant machining
• Center-cutting design enables direct plunge entry into workpiece material
• Coarse pitch, 2-flute helical geometry optimized for roughing and efficient chip clearance
• Right-hand cut with straight-cylindrical 6 mm shank for compatibility with standard toolholders

Compatibility

Designed for use with standard CNC toolholders and collet systems accepting a 6 mm straight-cylindrical shank. Rated for cutting steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per OSG material codes P, M, K, N, S, and H.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout at the tool tip before beginning a cut, as excessive runout on a small-diameter carbide end mill accelerates breakage.
