Why the Double Cut Design Brings Smoother, Controlled Finishing
Think of the double cut feature like walking on a finely textured sidewalk versus a rough gravel path. The combined right and left hand flutes of this burr make for a cutting action that’s gentler and more balanced, letting you glide through metal surfaces with greater control and leaving behind a smooth finish. This slight left hand cutting action acts like a steady guide, preventing the tool from grabbing too aggressively and helping you shape or polish more precisely.
