1/4" (6.3mm) x 1-1/2" (38.1mm)
The Kutzall Original tool line provides a fast stock removal with an outstanding finish, making them the most universal and best value of Kutzall tools. 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; the heat won't harm the teeth. This burr is also available in a 6mm shank.
