Coltene Crown Cutter Bur

The New Generation monoblock tungsten carbide cutter has an advanced technology design for rapid reduction. The computer-designed flutes cut more concentric, eliminate chatter and vibration, cut longer and let you reduce the preparation and chair time.

Carbide Burs offer an unparalleled concentric design reducing chatter and minimizing vibrations.

Computer-aided design is at the heart of creating precision-crafted carbide burs. Multi-axial grinding processes implement carefully designed angulations, flute depths, rake angles, and blading for optimal geometry and cutting performance.

Features:-

• Cuts Faster
• Lasts Longer
• Provides Efficient cutting
• Premium quality
• Eliminates breakage, chatter & bounce of crowns

direction to use :-

• • Insert the instrument as deeply as possible into the chuck (Friction Grip).
  • Set the handpiece at the required working speed before applying the instrument to the treated area.
  • Apply a maximum operating force of 0.4 [N] and do not exceed a speed of 400’000 [rpm].
  • Activate water spray during the entire treatment (minimum 50 mL/min).
  • Regulate water flow in case of water excess or shortage.
  • It is recommended to use a dental dam.
  • Use the instruments over the entire length of their working part and not just at the tip, so as to avoid an unconscious increase of the contact pressure causing local overheating.
  • Once the preparation has been completed, remove the instrument from the site and allow it to come to a standstill.
  • It is recommended to wear gloves and safety glasses.
