Dental Bur Shank Adapter: 2.35mm to 1.6mm Converter Sleeve for Low Speed Handpiece, High Speed FG Bur to Low Speed RA HP Metal Chuck Bushing
$ 7.11
Item Number: SX3100
- Seamless Cross-Specification Shank Bridging: Modifies an ultra-thin 1.6mm FG high-speed bur profile to perfectly fit a universal 2.35mm low-speed line handpiece receiver. This allows doctors to safely repurpose existing high-speed crown cutters for slow, meticulous touch-ups or lab adjustments. Three-Jaw High-Friction Lock Collet: Outfitted with an intricate three-slot micro-fissure expansion mouth at the entry tip. As the converter assembly is compressed within the receiving handpiece chuck, the metal flaps clamp inward uniformly, maximizing friction-grip torque transfer and stopping the bur from flying out, slipping, or spinning out of synchronization during heavy-duty composite trimming. Zero-Wobble High Axial Concentricity: CNC-machined from a single block of hardened medical steel alloy under strict tolerances. This exceptional mechanical alignment guarantees near-perfect dynamic balance and zero axial wobble, reducing handpiece vibration, preserving internal bearing life, and shielding composite margins from structural micro-shattering. 134°C/135°C Universal Autoclave Compliance: Forged entirely from anti-corrosive surgical stainless steel that shows zero structural degradation through high-frequency clinic infection control loops. The unibody metallic shaft safely survives continuous rounds of automated chemical washer-disinfectors, heavy enzymatic ultrasonic cleaning, and 134°C saturated vacuum steam autoclave bags without rusting or seizing up. Knurled High-Friction Handling Grids: The upper barrel collar is texturized with subtle, micro-milled vertical stabilization ridges. These linear grids allow assistant staff to grip the slick adapter tightly with wet clinical gloves or dressing tweezers, streamlining chairside bur ejection and insertion sequences when prepping complex multi-unit bridges. Ultra-Compact B2B Logistic Volume: Due to its microscopic physical footprint, multiple packs can nest compactly inside high-density foam multi-unit cards. This packing efficiency reduces bulk volumetric metrics, delivering highly optimized landed cost freight profiles for global dental warehouse suppliers. Technical Specifications Matrix Product Classification: Rotary Handpiece Attachments / Mechanical Shank Reducers & Bushings Material Matrix Composition: Surgical-Grade High-Tensile Stainless Steel Alloy Dimensional Modification Core: Outer Diameter: 2.35mm (RA/HP Low Speed Standard) to Inner Diameter: 1.60mm (FG High Speed Standard) Chuck Locking Configuration: Three-Flap Linear Compression Friction-Grip Bushing Opening Sterilization Validation Threshold: 100% Fully Autoclavable (Validated to Overcome 134°C – 135°C Vacuum Steam Cycles) Primary Target Operational Workflows: Adapting High-Speed Diamond Burs for Slow Finishing, Lab Restorative Trimming, Acrylic Denture Remodeling, Chairside Composite Polish Adaptations, Repurposing Excess FG Stock Dynamic Rotation Rating: Safe for Continuous Low-Speed/High-Torque Operations (Match to Recommended Handpiece Max RPM Limits) ? Clinical Best Practice & Insertion Guidelines: Bur Insertion and Seating Engagement: Pick up a standard high-speed 1.6mm FG bur with a clean gauze pad. Align its shank with the top opening of the adapter sleeve, pushing it straight down until the trailing parameter parameter of the bur shaft sits flush into the metal receiving bed of the three-jaw micro-collet opening. Handpiece Connection Validation: Take the combined adapter-bur assembly and load the 2.35mm rear metal stem into your low-speed latch-type contra-angle or straight lab motor handpiece chuck. Secure the handpiece locking latch until it clicks, and give the bur a firm manual tug outward to ensure both the internal collet and external handpiece chuck have engaged perfectly. Decontamination Reprocessing Loop: Immediately post-procedure, open the handpiece chuck, extract the adapter piece, and eject the used bur by inserting a standard extraction pin or pushing tool into the adapter base window. Submerge the stainless steel sleeve in an enzymatic cleaning bath to clear out trapped composite sludge, rinse thoroughly with distilled water, wipe dry completely to prevent spot scaling, and seal in an indicator pouch for standard high-vacuum autoclaving at 134°C.
