Rated to 25,000 RPM, it is designed for aggressive material removal, deburring, shaping, and surface blending on a wide range of ferrous and non-ferrous metals. The double cut tooth pattern produces faster stock removal than single cut while leaving a reasonably smooth finish. The 3\/8 inch cutting diameter and 1\/4 inch shank make it compatible with standard die grinders and rotary tools used daily in fabrication, maintenance, and tool-and-die work.\u003c\/p\u003e\n\u003cp\u003eThis burr is suited for use in metal fabrication shops, maintenance and repair operations, and tooling environments where precise material removal is required. Its uncoated tungsten carbide head handles a broad range of materials including tool steel, 300 and 400 series stainless steel, cast iron, copper, hard and soft carbon steel, and titanium. It is typically installed by machinists, pipefitters, welders, and metal fabricators working in industrial or trade settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble cut tooth style for fast stock removal and smooth finish on metal workpieces\u003c\/li\u003e\n  \u003cli\u003eCylindrical no-end-cut (SA-3) head geometry for side cutting and slot work\u003c\/li\u003e\n  \u003cli\u003eTungsten carbide construction for hardness and wear resistance across demanding materials\u003c\/li\u003e\n  \u003cli\u003eRated to 25,000 RPM for use with standard pneumatic and electric die grinders\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank fits common collet sizes on rotary tools and die grinders\u003c\/li\u003e\n  \u003cli\u003eUncoated head suitable for direct use on stainless steel, cast iron, copper, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an SA-3 industry-specification cylindrical burr for use with 1\/4 inch collet die grinders and rotary tools.
