The H40 Bur is an instrument that has been specifically designed to ex-hibit a great cutting rate. It is more aggressive than standard carbide burs due to the angulation and positioning of the cutting dentates—there are 8 blades with an overall 4-mm working length. It has a 2-piece construction, including a stainless steel shank and a tungsten carbide working end. For more information, call (888) 566-3887 or visit kometusa.com.
