Sgs Pro 16428 Ball Abrasive Bur SD-3L6 3/8 Inch Double Cut

Product Description

The SGS PRO 16428 is a tungsten carbide ball-shaped abrasive bur designed for material removal, deburring, and shaping across a wide range of metals. Conforming to industry specification SD-3L6, this double-cut bur features a 3/8 inch cutting diameter and an uncoated tungsten carbide head that delivers consistent performance under high-speed operation. With an overall length of 6.3125 inches and a 1/4 inch shank, it fits standard die grinders and rotary tools commonly used in fabrication and maintenance environments. Maximum operating speed is 37,500 RPM. Licensed tradespeople and skilled machinists rely on this bur for precision material work on hard and demanding substrates.

This bur is suited for use on steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. It is a strong choice for weld blending, port matching, mold finishing, and deburring in both shop and field settings. The 5/16 inch length of cut keeps the working edge compact relative to the extended shank, which is useful for reaching into recessed or confined areas without sacrificing control.

Compatibility

Designed for use with standard 1/4 inch collet die grinders and rotary tools. Compatible with steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per manufacturer specification.

Installation Notes

This bur is installed and operated by machinists, tool and die technicians, pipefitters, and fabricators using air or electric die grinders. Always confirm the tool collet size matches the 1/4 inch shank before securing. Power down and de-energize the grinder before inserting or removing the bur. Do not exceed the rated 37,500 RPM and always wear appropriate eye and face protection when operating rotary abrasive tooling.
