Designed for use with die grinders and rotary tools, it removes material aggressively on a wide range of metals including hard and soft carbon steel, stainless steel, cast iron, copper, titanium, and tool steel. The double cut tooth pattern produces a finer finish than single cut while still clearing chips efficiently. With a 1\/4 inch cutting diameter, 3\/4 inch length of cut, and 2 inch overall length, this burr fits standard 1\/4 inch collets and is rated to 25,000 RPM.\u003c\/p\u003e\n\u003cp\u003eThis burr is suited for weld blending, deburring, port matching, and material removal in fabrication, maintenance, and repair applications across metalworking trades. The ball nose cylinder shape allows access to contoured surfaces, cavities, and inside radii where flat or cylindrical profiles cannot reach. It is commonly used by machinists, welders, pipefitters, and maintenance technicians working on ferrous and non-ferrous metals. The uncoated tungsten carbide head maintains edge integrity at elevated speeds without the brittleness of high-speed steel alternatives.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBall nose cylinder profile for contoured surfaces, cavities, and inside radii\u003c\/li\u003e\n  \u003cli\u003eDouble cut tooth style for faster material removal and smoother finish\u003c\/li\u003e\n  \u003cli\u003eTungsten carbide head rated to 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank fits standard die grinder collets\u003c\/li\u003e\n  \u003cli\u003eUncoated head suitable for dry cutting on a broad range of metals\u003c\/li\u003e\n  \u003cli\u003eIndustry specification SC-1 for cross-reference and replacement sourcing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with material applications including 300 Series Stainless, 400 Series Stainless, Cast Iron, Copper, Hard Carbon Steel, Soft Carbon Steel, Titanium, and Tool Steel.
