The Tapered Fissure Bur #702L is an all-purpose bur used to section teeth, gain endodontic access and is also useful as a general purpose bur. Tapered means the cutting diameter tapers towards the end of the bur and fissure means the bur can drill holes at its tip, as well as section teeth along its side. The larger the number, the larger the diameter of the bur. In this case, the #702L will leave a large-sized cutting gap, ideal for canines. FG stands for friction grip which is used for push button handpieces. The length of this bur is 25 mm which is considered surgical length and is helpful for gaining access to hard to reach teeth. The extra length of this bur can increase the chance of bending which can cause damage to the handpiece turbine.
