Foredom Step Drill Diamond 0.7

Description:

The Step Drill Diamond 0.7 is a highly specialized dental laboratory tool designed for precision drilling through extremely hard materials such as zirconia, porcelain, lithium disilicate, and ceramic-reinforced composites. Equipped with a durable diamond coating, it provides superior cutting efficiency and ensures smooth, controlled penetration in brittle substrates where accuracy is essential. With a 0.7 mm diameter, this step drill is ideal for creating micro-channels, ventilation holes, access points, and small refinement openings used in delicate prosthetic adjustments. The step-cut configuration allows gradual expansion of the drill path, minimizing stress fractures, chipping, or unwanted propagation cracks�problems commonly associated with ceramic drilling. Because ceramic materials generate significant heat under friction, the drill is engineered for optimal heat dissipation and efficient debris removal. This helps protect restoration integrity and enhances technician control throughout the drilling process. Its exceptional stability reduces vibration, ensuring predictable and repeatable results. The Step Drill Diamond 0.7 is frequently used for adjusting ceramic veneers, modifying zirconia crowns, refining internal seating areas, or preparing minimal-diameter openings for high-precision prosthetic components. It is also useful in custom abutment adjustments and delicate laboratory modifications that require micro-level accuracy. Overall, the Step Drill Diamond 0.7 is an indispensable tool for dental laboratories specializing in high-strength ceramic restorations. Its diamond coating, precision geometry, and controlled performance ensure safe, accurate drilling for highly technical prosthetic demands.
