Why Choosing Between Single and Double Cut Matters for Your Project
The SF-3 burr’s dual cutting options are like having two tools in one. Think of the single cut like a speedboat—it’s built to blast through material quickly, making it ideal when you need fast stock removal. On the other hand, the double cut acts like a smooth cruiser, combining right and left spirals to gently glide over surfaces, leaving behind a much finer finish.
This combination gives you control and versatility. Need to knock down bulk fast? Single cut has your back. Want to smooth things out nicely? Double cut is your partner. It’s like having the perfect chisel and sanding tool bundled up in one burr.
