The MI Stainless Steel Burs are engineered to selectively remove softened carious dentin without cutting healthy calcified dentin. MI SS Burs can be repeatedly autoclaved without the risk of corrosion. Its blade rake angles are specifically engineered to remove decalcified softened dentin. Cutting flutes have excellent wear resistance due to the hardness of the material. The 28mm MI SS Burs provide length to reach areas which are difficult to access. The 34mm length provides enhanced bur head visibility, ideal for use with a microscope.
