Why the Double Cut Option Makes Finishing a Breeze
Double cut burrs combine right and left-hand flutes so they cut smoothly and evenly, like having a tool that simultaneously sands and shapes. This balanced cutting action means less chatter and vibration, giving you a buttery-smooth finish even on tough metals. Imagine smoothing wood with two sandpaper sheets moving in opposite directions — that’s the vibe, only for metal.
