Grenade Long
390L‑314
(1.4 mm x 3.5 mm)
The elongated “grenade” head combines a bulbous tip with a slim shank, enabling smooth occlusal reduction and fissure shaping. Its 1.4 mm diameter offers excellent control for contouring occlusal surfaces, while the 3.5 mm cutting length reaches deeper grooves. This versatile diamond bur handles cavity preparation, crown and veneer work, and occlusal adjustments. Choose it when you need to blend bulk reduction with fine finishing in one instrument.
