The 330 Carbide Bur (Low Speed – RA) is a precision pear-shaped tungsten carbide bur designed for use with contra-angle low-speed handpieces. It offers excellent cutting efficiency, durability, and control, making it ideal for caries removal, cavity refinement, and conservative tooth preparation.

Features:

• Shape: Pear-shaped (ISO #330) – allows smooth entry and undercut formation.

• Shank Type: RA (latch-type) – suitable for low-speed contra-angle handpieces.

• Material: High-quality tungsten carbide – ensures long-lasting sharpness and wear resistance.

• Head Size: Ø 1.6 mm, depth approx. 0.9 mm.

• Precision Cutting: Provides clean, accurate cavity margins and reduces risk of enamel chipping.

• Controlled Speed: Designed for efficient caries removal and cavity refinement at low rotational speeds.

Applications:

• Conservative cavity preparations.

• Caries removal.

• Access refinement in endodontic and restorative procedures.

• Creation of undercuts for secure restorations.
