Why Double Cut Flutes Make a Smoother Finish
Double cut burrs blend right and left hand spiral flutes, creating a super smooth cutting action that feels like the burr is gently guiding itself. Think of it like smoothing a wooden table with fine sandpaper versus rough grit—double cut burrs work on metal in the same way, delivering precise control and cleaner edges, minimizing vibration and chatter.
