Foredom Step Drill Cobalt 1.7

Description:

The Step Drill Cobalt 1.7 is specifically designed for demanding dental laboratory procedures requiring stable, accurate drilling through dense metal substrates. Made from cobalt alloy steel, it delivers exceptional hardness and longevity while resisting heat buildup during prolonged use. This durability makes it well-suited to the high-precision environment of prosthetic fabrication. The drill�s 1.7 mm diameter is ideal for producing larger functional channels required in implant bar systems, screw-retained prosthetics, clip mechanisms, hinge assemblies, and structural components of partial denture frameworks. Its step-drill profile ensures smooth, progressive entry into metal, reducing the likelihood of sudden breakthroughs or microfractures that could compromise prosthetic accuracy. Advanced flute geometry promotes efficient removal of metal chips, maintaining a clear cutting path and minimizing heat accumulation. This contributes to cleaner drilling and prevents surface distortions that could affect prosthetic fit or mechanical reliability. Because precise alignment of attachment points is essential in implant-supported restorations, the Step Drill Cobalt 1.7 provides consistent, predictable results. Technicians rely on this drill for modifying titanium abutments, adjusting cobalt-chromium partial frameworks, crafting custom implant bars, and preparing metal prosthetic housings. Its dependable performance helps maintain structural integrity in restorations and ensures optimal mechanical retention. Overall, the Step Drill Cobalt 1.7 delivers the strength, accuracy, and stability required for advanced restorative and implant dentistry. It is a reliable addition to any dental laboratory focused on precision metalwork and long-lasting prosthetic outcomes.
