About this product
GZH243-5C is designed for extraoral dental laboratory finishing of pre-sintered zirconia restorations. The slim tapered profile helps technicians refine grooves, embrasures, cusp anatomy, and narrow contour areas while the gray coarse abrasive supports efficient green-state material removal. The Aluminum Oxide abrasive in a silicone binder is suited to the lower strength of pre-sintered zirconia, helping shape milled crowns and bridges before the final furnace cycle. Use with light pressure, dust extraction, and a stable HP handpiece for controlled grinding without overloading delicate unsintered restorations.
