Sgs Pro 13753 Abrasive Bur SF-53 Tree with Radius

Product Description

The SGS PRO 13753 is a double cut tungsten carbide abrasive bur in the SF-53 tree with radius (ball nose tree) geometry. Designed for aggressive material removal and finish work in tight contours and curved surfaces, this bur operates at speeds up to 75,000 RPM. The 1/8 inch shank fits standard die grinders and rotary tools used by machinists, fabricators, welders, and tool and die technicians. The uncoated tungsten carbide head delivers hardness and edge retention across a broad range of ferrous and non-ferrous workpiece materials. Overall length is 1.5 inches with a 3/16 inch cutting diameter and a 1/2 inch length of cut.

This bur is suited for deburring, blending, contouring, and material removal on ferrous metals including steel, hardened steel, stainless steel, and cast iron, as well as non-ferrous materials such as titanium, nickel, copper, and copper alloys. The ball nose tree profile is particularly effective in radiused pockets, port work, mold cavities, and weld cleanup where a curved cutting surface is needed to match the workpiece geometry. It is used in both production and repair environments across metal fabrication, automotive, aerospace, and tooling shops.

Key Features

• SF-53 ball nose tree geometry for radiused contours and curved surface work
• Double cut tooth pattern for fast stock removal with reduced chatter
• Uncoated tungsten carbide head for hardness and wear resistance
• Rated up to 75,000 RPM for use with high-speed die grinders
• 1/8 inch shank compatible with standard rotary tool collets
• Effective on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/8 inch collet. Suitable for material removal, deburring, and contouring on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per the SF-53 industry specification.

Installation Notes

This bur is installed by machinists or fabricators using a die grinder or rotary tool with a matching 1/8 inch collet. Secure the shank fully into the collet and tighten per the tool manufacturer torque guidance before operation. Always wear appropriate eye protection and confirm the tool RPM rating meets or exceeds the bur maximum of 75,000 RPM. Inspect the bur for cracks or chipping before each use and do not exceed the rated speed.
