Sgs Pro 12078 SC-12 Ball Nose Cylinder Carbide Bur

Product Description

The SGS PRO 12078 is a double cut tungsten carbide abrasive bur in the SC-12 ball nose cylinder (cylinder with radius) configuration. Designed for aggressive material removal and finishing in die grinders and rotary tools, this bur features a 1/8 inch cutting diameter and a 1/4 inch shank diameter, with an overall length of 2.375 inches and a 0.625 inch length of cut. The double cut tooth pattern shears material in two directions, improving stock removal rates and reducing vibration. Machinists, tool and die makers, and fabricators rely on this style of bur for deburring, shaping, and surface blending across a wide range of metals.

This bur is suited for use on ferrous and non-ferrous metals in both production and maintenance applications. The ball nose cylinder profile makes it effective for contouring, blending radii, and working in slots or recessed areas where a flat-end geometry would be limited. It is sized for 1/4 inch collet die grinders commonly used in machine shops, fabrication shops, and weld finishing operations.

Key Features

• SC-12 ball nose cylinder geometry for contouring and radius blending
• Double cut tooth style for faster stock removal and reduced chatter
• Tungsten carbide head for extended tool life on hard materials
• Uncoated head - no coating buildup risk in gummy or soft metals
• Rated up to 100,000 RPM for use in high-speed die grinders
• 1/4 inch shank fits standard die grinder collets

Compatibility

Designed for use with standard 1/4 inch collet die grinders and rotary tools. Suitable for cutting steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys per industry specification SC-12.

Installation Notes

Installation and use of carbide burs is typically performed by machinists, fabricators, or tool and die technicians. Ensure the die grinder is fully powered off and the collet is released before inserting or removing the bur. Secure the shank fully into the collet to the recommended depth to prevent runout or ejection at high RPM. Always wear appropriate eye protection and follow the tool manufacturer's maximum RPM guidelines - this bur is rated to 100,000 RPM.
