Insert the bur fully into the handpiece chuck and tighten securely. Run the handpiece at the recommended speed: High-speed FG burs: 1,50,000–3,00,000 rpm Low-speed RA burs: 10,000–40,000 rpm Apply light, intermittent pressure—avoid excessive force to prevent bur breakage. Use adequate water spray/coolant to avoid overheating.

Material: Head — tungsten carbide (cemented carbide), Shank — stainless steel. Hardness & durability: Tungsten carbide is much harder than steel (approx. 3× rigidity vs. steel) and highly wear-resistant, enabling longer cutting life and high-speed use. Working mechanism: Cutting by blade-like flutes — not abrasive grinding. This yields smoother cuts, less vibration / heat, and better control. Shapes & Cuts: Multiple options depending on use. Common shapes include round, cylinder (straight or tapered), pear, flame, torpedo, etc. Cut types include single-cut, cross-cut, finishing, etc., to adjust aggressiveness and finish quality. Shank / Attachment Type: Carbide burs are available for high-speed handpieces (friction-grip, “FG”, turbine) and for contra-angle / low-speed handpieces (latch-type or “RA”), as well as straight-handpiece (HP) versions depending on need. Sterilisation / Reusability: Dental carbide burs (non-single use) can be cleaned mechanically and sterilized (steam sterilization in gravity or prevacuum cycle) before reuse. Applications / Use Cases: Cavity preparation, caries removal, enamel/dentin cutting, removal of old restorations (amalgam, metal, porcelain-fused crowns), crown/bridge removal or reshaping, bone trimming, endodontic access, finishing & polishing of restorations, restorative margin shaping, contouring, etc.
