Foredom Step Drill 2.2

Description:

The Step Drill 2.2 is a specialized dental laboratory tool engineered to increase hole diameters with outstanding control and accuracy. Its stepped geometry gradually widens the cut to a precise 2.2 mm diameter, eliminating the risk of sudden expansion or misalignment commonly associated with traditional twist drills or rotary burs. This makes it ideal for installing housings, mechanical attachments, implant retention elements, and structural fittings that require exact hole sizing. Technicians rely on the Step Drill 2.2 for modifying metal partial denture frameworks, implant bar designs, acrylic prosthetic components, and orthodontic appliance bases. Its controlled cutting action ensures concentric hole enlargement while protecting the restorative material from fractures, irregularities, or heat damage. This precision is crucial when fitting components that must perform under functional load and require long-term stability. Constructed from high-quality carbide or hardened metal alloys, the drill provides consistent cutting sharpness, durability, and resistance to wear. It performs efficiently on materials such as titanium, stainless steel, chrome-cobalt, and nickel-chrome alloys, as well as acrylics and thermoplastics widely used in prosthetic fabrication. In addition to enlarging holes, the Step Drill 2.2 also helps improve internal hole smoothness, ensuring secure, friction-free seating of attachments or housings. This contributes to improved prosthetic retention, reduced mechanical wear, and enhanced reliability of the final restoration. For dental technicians seeking precise, controlled, and reliable hole enlargement, the Step Drill 2.2 is a vital tool that ensures accuracy, efficiency, and long-lasting restoration performance.
