The Carbide Smooth Cylindrical Operating Drill Bit with
Plana No. 56 FG Invicta from American Burrs was developed to create preparations with parallel walls and a flat floor, useful for creating the periphery of the preparation.
Renowned for its high efficiency and innovative design, the tip is made of 100% fine-grain K20 tungsten carbide, which maintains its shape as it wears. It features Mirror Gridin technology, where the blade structure with the inclination angle and depth of the spiral results in powerful cutting performance, with reduced vibration and lower risk of fracture.
