Sgs Pro 12528 SD-4 Ball Carbide Burr 7/16 in Double Cut

Product Description

The SGS PRO 12528 is a double-cut tungsten carbide rotary burr in the SD-4 ball head configuration. Designed for aggressive material removal and fine finishing, this burr operates at up to 28,000 RPM and features a 7/16 inch cutting diameter with a 3/8 inch length of cut. The 1/4 inch shank fits standard die grinders and rotary tools used throughout metal fabrication, maintenance, and industrial repair work. The uncoated tungsten carbide head delivers consistent cutting performance across a wide range of ferrous and non-ferrous materials. Machinists, pipefitters, welders, and tool-and-die tradespeople reach for this style of burr for deburring, contouring, and cavity work.

The 12528 ball burr is suited for work in confined areas where a rounded cutting profile is needed to blend, enlarge, or finish curved surfaces and rounded cavities. The SD-4 geometry combined with double-cut fluting clears chips efficiently, reducing heat buildup during extended passes. Compatible material applications include steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys, making this burr a practical choice for shops handling mixed-metal workloads.

Key Features

• Double-cut fluting for fast stock removal and a smoother finish pass
• Tungsten carbide head construction for extended service life on hard metals
• Ball SD-4 head shape reaches curved surfaces, cavities, and contoured workpieces
• Rated to 28,000 RPM for use with standard pneumatic and electric die grinders
• 1/4 inch shank diameter fits the most common collet sizes in the trade
• Uncoated head works across ferrous and non-ferrous material applications

Compatibility

Compatible material applications include steel, hardened steel, stainless steel, cast iron, titanium, nickel, copper, and copper alloys. Fits any die grinder or rotary tool accepting a 1/4 inch shank collet.

Installation Notes

Secure the 1/4 inch shank fully into the collet before operation and verify the locking mechanism is tight. Do not exceed the 28,000 RPM maximum speed rating. Always wear eye protection and appropriate PPE when operating rotary burrs, as chips and debris are ejected at high velocity. Inspect the burr for cracks or missing flute segments before each use and replace if any damage is found.
