Sgs Pro 11853 SC-4 Carbide Bur Ball Nose Cylinder 7/16 in

Product Description

The SGS PRO 11853 is a double cut tungsten carbide abrasive bur in the SC-4 ball nose cylinder profile, designed for aggressive material removal and fine finishing in metalworking and fabrication applications. The 7/16 inch cutting diameter and 1 inch length of cut make it well suited for contouring, deburring, and shaping in confined areas. With a 1/4 inch shank and an overall length of 2-3/4 inches, it fits standard die grinders and rotary tools used daily by machinists, welders, pipefitters, and fabricators. The double cut tooth pattern clears chips efficiently and reduces heat buildup during extended use.

This bur is rated for use on a broad range of metals including steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. It is a practical choice for weld blending, port matching, gasket surface prep, and general stock removal in both shop and field environments. The SC-4 geometry allows the operator to reach into curved or radiused cavities that straight cylinder burs cannot access cleanly. Typical users include structural fabricators, pipe welders, aerospace technicians, and tool and die shops.

Key Features

• SC-4 ball nose cylinder profile for radiused cavity access and contour work
• Double cut tooth style for fast stock removal with reduced chatter
• Tungsten carbide head construction for hardness and wear resistance
• Compatible with steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys
• Maximum rated speed of 28000 RPM for use with standard pneumatic and electric die grinders
• 1/4 inch shank fits the most common collet size on rotary and die grinder tools

Compatibility

Designed for use with die grinders and rotary tools accepting a 1/4 inch collet. Suitable for the material types listed in the specifications section.

Installation Notes

Installation and use should be performed by a qualified machinist, fabricator, or tradesperson familiar with rotary cutting tools. Verify the die grinder or rotary tool is rated at or above the bur maximum RPM before mounting. Ensure the shank is fully seated and the collet nut is tightened securely before operating. Always wear appropriate eye protection and follow applicable shop safety procedures when using abrasive rotary burs.
