How the Double Cut Design Gives You Smoother Results
At first glance, cutting flutes might sound like tech-talk, but it’s simply how the burr’s teeth carve through metal. The SB-53 L3’s double cut features flutes spiraling both right and left, much like combining a right and left twist on a ribbon. This means it slices through material more finely, giving you a smoother, cleaner finish with less effort. Imagine sanding wood vs. planing it; the double-cut burr is like the planer that leaves a polished surface ready for painting.
