Sgs Pro 11803 Carbide Bur SC-3L Ball Nose Cylinder Double Cut

Product Description

The SGS PRO 11803 is a double-cut tungsten carbide abrasive bur in the SC-3L ball nose cylinder profile. The cutting head measures 3/8 inch in diameter with a 1-inch length of cut, and the tool runs on a 1/4-inch shank with an overall length of 2.75 inches. Rated to 37,500 RPM, it is designed for aggressive material removal and finishing work on metals including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. The double-cut tooth pattern produces a smoother finish than single-cut while maintaining fast stock removal. Machinists, tool-and-die workers, and fabricators reach for this bur when working in die grinders and rotary tools.

The SC-3L profile suits deburring, port and cavity work, chamfering, and contour blending in both production and maintenance applications. The ball nose cylinder geometry allows the tool to reach into blind pockets and curved surfaces that straight-cylinder burs cannot address cleanly. It is equally suited for general fabrication shops and precision machining environments where tight radii or internal profiles need to be worked by hand tool. The 1/4-inch shank fits standard die grinder chucks without an adapter.

Key Features

• SC-3L ball nose cylinder profile for curved-pocket and contour access
• Double-cut tooth pattern for fast removal with a relatively smooth finish
• Tungsten carbide head - uncoated - handles hardened ferrous and non-ferrous metals
• 37,500 RPM maximum rating suits high-speed die grinders
• 3/8 inch cutting diameter with 1-inch length of cut
• Standard 1/4-inch shank fits most die grinders and rotary tools without adapters

Compatibility

Compatible material applications listed by the manufacturer include steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. The 1/4-inch shank fits standard die grinder collets and rotary tool chucks rated for that shank diameter.

Installation Notes

This bur is installed and operated by machinists, fabricators, or maintenance technicians using a die grinder or rotary tool. Secure the shank fully in the collet and verify the chuck is tightened before operation. Always wear eye protection and appropriate gloves when running carbide burs, and do not exceed the 37,500 RPM maximum speed rating. Inspect the bur for chipping or damage before each use and replace if the cutting edges show wear that would affect safe operation.
