• Industrial-Grade Durability: Boron nitride burrs have tightly bonded particles, staying steady and sharp when grinding turbine blades, titanium alloy parts, or stainless steel valves. Rubber-mixed abrasive grains soften contact and leave smoother surfaces, ideal for flange sealing surfaces or internal hole polishing.
• Broad Metal Compatibility: These boron nitride burrs excel at grinding black metals—stainless steel, hardened steel, high-speed steel, mold steel, tool steel, carbon steel, plus steel bearings, valve parts, piston materials, and high-temperature alloy heat-treated materials—working well for common and precision metals.
• Precision for Detail Work: Designed for CNC machines/grinders, these burrs enable high-precision internal cylindrical grinding on bearing races, gear teeth, die-casting mold cavities. They remove uneven edges, resist wear, ensuring professional quality for mold parts or machine bed guide rails.
• Long-Lasting Coating: Tough boron nitride coating bonds tightly to a high-quality steel core. Far more durable than regular abrasive bits, it resists wear and maintains sharpness on carbide, titanium alloy, iron, or stainless steel valve trims, even for tough jobs.
