The Kutzall tool line is designed to provide fast stock removal with an outstanding finish, thanks to exclusive tungsten-carbide coatings that make it the best value in the industry. The 1/4"-shaft burrs are used in flex shaft tools, hand grinders, or other machinery using 1/4" collets or adjustable chucks. They are not prone to loading, but may easily be cleaned with solvent or burned clean with a gas torch. Heat generated from the torch will not harm the teeth. Kutzall burrs are handmade in America (the Motor City suburbs, to be exact!).
Note: Diameter and head length dimensions on Kutzall burrs are base dimensions. The coatings add approximately .060" - .160".
