Metal Cutting Burs (Tungsten Carbide).

Applications:

• Specially recommended for cutting crowns and bridges (gold, nickel-chromium and other non-precious alloys). The active axial part is applied to the surface to be cut with moderate pressure. An alternating up and down movement improves the efficiency of the bur.
• Recommended speed: between 120’000 and 180’000 rpm.

Characteristics:

• Spiral drill with extra-fine cross cut guaranteeing effective debris removal (no accumulation), hence preventing heating.
