DIYers, hobbyists, woodworkers, stone carvers, machinists, high-volume parts producers, and crafters let our Tungsten Carbide Round Tree Rotary Burrs be an excellent addition to your workshop. Our Tungsten Round Tree Rotary Burrs are ideal for rounding off edges and making concave cuts. You can use the pointed end for cutting into those hard-to-reach areas and acute-angled contours that come up. Our rotary burrs last much longer than standard burrs and will significantly increase productivity. You can use this on your next wood, stone, metal-based project. To show the toughness our burrs are, you can even use them on HRC 65 hardened steel for your next metalworking project. Our Tungsten Carbide Round tree Rotary Burrs connect to your basic hobby drill, micro motor, or high-speed tools.
