Attritor GZH275-8C pre-sintered zirconia finishing bur

Description

The Attritor GZH coarse bullet-shape bur shapes and contours 8.5x13mm 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, bullet shape for 8.5x13mm 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 flame contour (5.5x13mm): use GZH243-5C.

→ 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.
