Carbide Bur Heads RA for Contra-Angle, Super-Hard, 22 mm, Pack of 5 - Spherical, Tapered, Cylindrical, or Pointed

This set contains 5 extra-hard carbide burs heads for contra angle (RA), manufactured from tungsten carbide steel, a material recognized for its high wear resistance, extended durability, and consistent cutting performance. The burs feature a silver finish and are available in various shapes and sizes to suit different procedures: spherical codes (RA2, RA3, RA4, RA5, RA6), tapered (RA35, RA36), and cylindrical (RA557, RA558).

These burs are designed for versatile use in both dental laboratories and clinical settings. Their geometry allows precise cutting, improved stability during operation, and reduced vibrations, which support efficient and controlled work when attached to RA contra-angle handpieces.

Technical specifications:
• Material: tungsten carbide steel, high resistance to wear and corrosion
• Extra-hard grade for longer lifespan and consistent performance
• Silver metallic finish
• Available in spherical, tapered, cylindrical, and elongated shapes
• Compatible with standard RA (latch-type) contra-angle handpieces
• Engineered for precise, controlled cutting and stable performance

Recommended applications:
• Crown and bridge removal in restorative procedures
• Finishing and adjustment of acrylics, composites, and conventional filling materials
• Excavation and removal of amalgam restorations
• Use as surgical bone burs in specific dental interventions

Usage guidelines:
• Operate at speeds between 20,000 and 30,000 rpm, without applying excessive pressure
• Avoid continuous operation without cooling intervals to prevent overheating
• Follow immersion times and disinfectant concentration precisely during pre-sterilization
• Autoclave sterilization is recommended for reliable hygiene and safety

Safety instructions:
• Always adhere to sterilization and disinfection guidelines to prevent breakage or premature wear
• Do not apply unnecessary force while cutting
• Ensure compatibility with RA contra-angle handpieces before use

In conclusion, this RA carbide burs set provides a durable and versatile solution for dental applications, combining strong material properties with multiple shape options to cover a wide range of laboratory and clinical procedures.
