Sgs Pro 13378 SF-5 Tree Radius Carbide Bur 1/2 in

Product Description

The SGS PRO 13378 is a double cut tungsten carbide abrasive bur in the SF-5 tree with radius (ball nose tree) profile. It is designed for aggressive material removal and contour finishing in die grinders and rotary tools. The 1/2 inch cutting diameter and 1 inch length of cut make it well-suited for cavity work, port blending, and weld prep. At up to 28000 RPM, it delivers fast stock removal in a wide range of metals. The 1/4 inch shank fits standard collet chucks on most rotary tools and die grinders. Machinists, tool and die workers, welders, and fabricators are the primary installers and users of this bur.

This bur performs across a broad spectrum of metalworking applications. It is appropriate for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Typical use cases include deburring, flashing removal, weld prep, porting, and die finishing in both job shop and production environments. The tree with radius shape allows access to curved interior surfaces and contoured cavities where flat-end profiles cannot reach.

Installation Notes

This bur is installed by machinists, fabricators, and tool and die technicians using standard die grinders or rotary tools. Ensure the tool is fully powered off and the collet is released before inserting or removing the bur. Inspect the shank for runout or damage before use, and do not exceed the rated 28000 RPM. Wear appropriate eye protection and secure the workpiece before operation.
