Detailing a woodcarving? Trimming some burr material or cutting metal? Our WoodRiver® Carbide Burr Set will handle both jobs with aplomb. You get 20 burrs – 10 double-cut and 10 single-cut in profiles, including balls, pointed cones, rounded cones and cylinders. All the burrs are approximately 1-7/16" in length, with the cutter length varying with the burr type, and all with 3mm heads (or smaller) and shanks. 3mm shanks? Don’t panic! They’ll fit 1/8" collets in all the popular rotary and flex shaft machines on the market. We consider this set as a must-have around the shop, because it switches so easily between wood and metal.
