Why Dual Cut Options Make Your Work Smoother
Choosing between standard cut and double cut can seem tricky, but it’s about matching the burr’s aggressiveness to your task. Think of the standard cut like a steady hand that removes material smoothly, great for finishing touches. The double cut? That’s more like a power tool’s turbo mode—it removes material faster and keeps the surface clean by breaking chips into smaller bits, which prevents clogging.
This versatility means you can switch cuts depending on your project’s needs—whether you’re finely shaping wood or quickly deburring metal edges. It’s like having two burrs in one!
