Very Coarse | 1/8" (3.1mm) x 7/8" (22.2mm)
When you need to remove material in hurry but still require precise control, there are no better tools for the job than Kutzall Extreme Burrs. The Extreme Burrs come equipped with a rugged, very coarse coating applied by fellow craftsmen. The aggressive, razor-sharp, tungsten-carbide teeth hog material away with unparalleled efficiency, while also resisting loading. This lets you spend more time carving, and less time clearing your tool. The 1/8" shaft burrs are used in flex shaft tools, small rotary grinders, or other machinery using 1/8" collets or adjustable chucks.
