Osg 902-2500 Carbide Abrasive Bur SC-1 1/4 Inch Shank

Product Description

The OSG 902-2500 is a single-cut carbide abrasive bur in the SC-1 ball nose cylinder profile, designed for aggressive material removal and contouring in hard metals. With a 1/4-inch shank diameter and a 1/4-inch cutting diameter, this bur fits standard die grinders and rotary tools used across metalworking, fabrication, and maintenance trades. The uncoated carbide head delivers consistent cutting performance at speeds up to 70,000 RPM. The single-cut tooth style produces a smoother finish and generates larger chips, making it well-suited for fast stock removal on tough materials without clogging. Overall length is 2 inches with a length of cut of 5/8 inch.

This bur is rated for use on steel, stainless steel, cast iron, superalloys, and titanium, making it a practical choice for industrial maintenance, weld finishing, port work, and deburring in demanding fabrication environments. The SC-1 ball nose cylinder geometry allows access into contoured surfaces, cavities, and radius blends where flat-end burs cannot reach. It is sized for precision handheld work by machinists, tool and die makers, and metal fabricators who need controlled material removal on hard-to-machine alloys.

Key Features

• SC-1 ball nose cylinder profile for contouring and radius blending in recessed areas

Compatibility

Designed for use with standard 1/4-inch collet die grinders and rotary tools. Rated for cutting steel, stainless steel, cast iron, superalloys, and titanium per the SC-1 industry specification.

Installation Notes

Secure the shank fully into the collet before operation and verify the collet nut is properly tightened. Always confirm the tool RPM rating meets or exceeds the spindle speed before use — never exceed 70,000 RPM with this bur. Wear appropriate eye protection and gloves when operating rotary carbide burs on hard metals. Inspect the head for chipping or damage before each use and replace if cutting edges are compromised.
