NeoBurr® FG 701 Crosscut Tapered Fissure Operative Carbide Bur by Microcopy (USA). Engineered from a single piece of solid tungsten carbide with a standard friction grip shank and a 3.8 mm crosscut tapered fissure cutting head. Specifically designed for rapid hard-tissue removal, establishing divergent axial walls without undercuts, and efficient sectioning of old restorations for inlays, onlays, and crown preparations.

Key Features:

• Aggressive Crosscut Geometry: Horizontal serrations across the tapered cutting blades break down tough enamel and restorative materials rapidly into small chips, delivering exceptionally fast cutting efficiency with minimal handpiece pressure.
• Undercut-Free Tapered Profile: Conical taper establishes precise divergent axial walls essential for indirect restoration paths of insertion (inlays, onlays) and proper draw for cast restorations.
• Restoration Sectioning & Removal: Proven blade geometry for rapid sectioning of old amalgam restorations, cutting through base materials, and gross reduction in crown preps without clogging.
• Single-Piece Solid Carbide Construction: Integrated blended-neck architecture eliminates brazed joint failure points, maximizing shear strength and minimizing head breakage under high lateral forces.
• Enhanced Debris Clearance: Crosscut channels allow rapid irrigation fluid flow and debris evacuation, preventing bur clogging and reducing thermal stress on tooth structure.
• Sterile Single-Patient Safety: Individually blister-packaged and pre-sterilized to prevent cross-contamination and guarantee razor-sharp performance straight from the package.
• True Concentric Rotation: Precision Swiss-machined shank ensures true concentricity, protecting turbine chucks and handpiece bearings from premature wear.
