Why Double Cut Burrs Deliver Ultra-Smooth Finishes
Double cut burrs feature two sets of flutes spiraling in opposite directions, which is like having two chefs carefully slicing a loaf of bread instead of one. This design allows the burr to remove material more evenly and gently, reducing vibrations and chatter. As a result, you get an ultra-smooth surface that needs less polishing afterward—saving you time and effort on every job.
