Clinical Use
- Laboratory and denture work: the HP carbide version trims acrylic, adjusts denture bases and reduces plaster models in the straight handpiece.
- Straight-walled cuts: the flat-end cylinder cuts straight-walled slots, channels and flat seats in acrylic, wax and model materials.
At 0.9 mm the No. 1556 is a fine head for narrow slots and detail work in the laboratory.
