Green-state Zirconia
● Coarse
Description
The ATTRITOR GZH coarse flame-shape bur shapes and contours 5.5x13mm green-state Zirconia fast and clean while the material is still soft and chalky — saving your diamonds for fully-sintered work and cutting bench time spent grinding fired ceramic.
- ✓ Coarse grit, flame shape for 5.5x13mm contouring
- ✓ Fast green-state stock removal before sintering
- ✓ Standard HP lab shank (2.35 mm)
- ✓ For pre-sintered (green-state) Zirconia only
Why You’ll Love It
✦ Shapes soft green-state Zirconia fast — less time grinding fully-fired ceramic.
✦ Saves your diamonds — adjust before sintering, not after.
✦ Pigment-free, HP-mounted — true shade, standard handpiece.
If You Are Looking For…
→ Coarse reduction on a bullet contour (8.5x13mm): use GZH275-8C.
→ Coarse reduction on a wheel contour (15x3.4mm): use GZH040-15C.
→ 2-in-1 polish on a bullet contour (10x22.5mm): use GZH507-10MF.
→ 2-in-1 polish on a point contour (7x19mm): use GZH507-7MF.
→ Everything in one box: use the ZET-USDD 9-piece set.
Handling
- Use in a standard HP lab handpiece at a comfortable bench speed; let the bur do the work on soft green-state material.
- Avoid overheating — light, intermittent pressure preserves the instrument.
- Clean Zirconia dust under running water and follow your lab’s instrument-hygiene protocol.
