Defend Operative Carbide Burs, RA, Round, # 4, 1.4 mm, 10/Pk, RA-4

Defend Operative Carbide Bur is a durable rotary instrument built from medical-grade tungsten carbide, making it significantly tougher than stainless steel for a reliable and lasting trimming performance. Due to its concentric rotational operation, Defend Operative Carbide Bur allows dentists to cut or shape the tooth or dental material with much accuracy and consistency while preventing chatters and vibrations. Dentists utilize the carbide tool for multiple dental procedures, such as creating endodontic access, removing old fillings, or preparing the tooth for prostheses.
