The Coltene Whaledent Alpen Diamond Instruments 909-314-040-1.00-C is a highly effective 04.0 mm round wheel diamond bur for rapid tooth reduction, featuring a coarse grit and a 1.0 mm head length, provided in a package of 5 burs per pack. This high-quality, multilayer diamond instrument is designed for use in high-speed handpieces (Friction Grip - FG) and is the definitive choice for any dental professional performing gross reduction of tooth structure, especially during crown and bridge preparation, or for precise occlusal adjustments.

Its unique round wheel shape (ISO 909) with a 4.0 mm head diameter is specifically engineered to achieve efficient and aggressive material removal, which is crucial for establishing depth cuts and reducing the occlusal and incisal surfaces. If you're searching for a highly effective and reliable diamond bur tool for superior crown preparation and rapid material removal, the best Coltene Whaledent Alpen Diamond Instruments 909-314-040-1.00-C is a definitive choice for any dental professional. The coarse grit (C), typically identified by a green band, ensures fast cutting with less pressure, helping to minimize heat generation and patient discomfort during the most demanding reduction procedures.

The multilayer diamond coating of the Alpen instruments provides an exceptionally long working life and consistent cutting efficiency because new, sharp diamond grains are continuously exposed as the outer layer wears down. Manufactured with Swiss precision, these diamond burs are an essential instrument for achieving optimal preparation geometry and facilitating the successful fit of final restorations. The 1.0 mm working length is ideal for controlled depth-of-cut adjustments.
