Sgs Pro 13900 Carbide Bur Tree 3/8 Inch Single Cut

Product Description

The SGS PRO 13900 is a single-cut tungsten carbide abrasive bur with a tree-with-pointed-end head shape, designed for material removal, deburring, shaping, and finishing in metalworking applications. The bur features a 3/8 inch cutting diameter and a 3/4 inch length of cut, with an overall length of 2.5 inches and a 1/4 inch shank diameter for use in standard die grinders and rotary tools. The uncoated tungsten carbide head delivers consistent cutting performance across a broad range of ferrous and non-ferrous metals. Rated to 37,500 RPM, it is suited for high-speed material removal in shop and field environments. Machinists, tool and die workers, and fabricators are the primary users.

This bur is intended for use on steel, hardened steel, stainless steel, cast iron, titanium, cermet, nickel, copper, and copper alloys. The tree-with-pointed-end profile makes it well suited for contouring, reaching into cavities, and shaping irregular or recessed surfaces. It fits standard 1/4 inch collet die grinders and is commonly used in fabrication shops, tool rooms, and maintenance operations where precision material removal is required on hard metals.

Installation Notes

Install the bur securely into a 1/4 inch collet and tighten to the tool manufacturer's specified torque before operation. Verify the tool is rated to handle the bur's maximum RPM of 37,500 before use. Always wear appropriate eye protection and ensure the workpiece is properly secured. Do not exceed the rated RPM, and inspect the bur for wear or damage before each use.
