Sgs Pro 13703 Abrasive Bur SF-42 Tree with Radius

Product Description

The SGS PRO 13703 is a double cut tungsten carbide abrasive bur in the SF-42 tree with radius (ball nose tree) profile. Designed for aggressive material removal and finishing work, this rotary bur runs on die grinders and rotary tools at speeds up to 100,000 RPM. The double cut tooth pattern produces faster stock removal and a smoother surface finish compared to single cut geometry. With a 1/8 inch shank diameter and 1/2 inch length of cut, it fits standard collet tooling and delivers controlled material removal in tight access areas. Machinists, tool and die workers, and fabricators reach for this bur when deburring, porting, or shaping ferrous and non-ferrous metals.

The SF-42 profile is suited for contouring curved surfaces, blending radii, and working in recessed cavities where a ball nose geometry is required. It is compatible with a wide range of materials including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Typical applications include weld blending, port and chamber work, mold and die finishing, and general deburring in fabrication and maintenance environments. The uncoated tungsten carbide head maintains sharp cutting edges across demanding materials.

Key Features

• SF-42 ball nose tree profile for contouring curved surfaces and blending radii
• Double cut tooth style for fast stock removal and improved surface finish
• Tungsten carbide head handles steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys
• Rated up to 100,000 RPM for use with high-speed die grinders and rotary tools
• 1/8 inch shank fits standard collet tooling widely available in the trade
• Uncoated head maintains consistent cutting performance across the full range of rated materials

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch collet. Rated for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per industry specification SF-42.

Installation Notes

Install the shank fully into the collet of the die grinder and tighten the collet nut securely before operation. Confirm the tool is rated for the RPM of the grinder before mounting. Always wear appropriate eye protection and secure the workpiece before operating the bur. Do not exceed the rated maximum RPM of 100,000.
