How Choosing Between Single and Double Cut Makes a Difference
The cutting style of your burr affects not just the finish but also the control and speed of your work. Think of Single Cut burrs like a chef’s sharp knife — great for chopping through material quickly and efficiently. They’re perfect when you need to remove a lot of metal without worrying too much about the surface finish.
Double Cut burrs, on the other hand, are like using a finely honed paring knife. The two flutes (right and left hand spirals) work together to slice more smoothly, producing a cleaner, polished surface with less vibration. It also provides better control, which is especially useful when working on delicate or detailed areas. Understanding this can help you pick the right burr to make your job easier and your results sharper.

Keeping It Going
