Needle 
859‑314
(Ø1.4 mm x 10 mm)
This slender 1.4 mm needle bur offers a 10 mm working length for deep access in interproximal or occlusal areas. It excels at occlusal reduction, cavity preparation and crown and bridge preparation. The needle shape allows precise groove cutting and margin refinement without removing excess tooth structure. Choose it for fine finishing, interproximal reduction and accessing narrow fissures where a conventional taper bur would be too bulky
