How do these burs perform on zirconia compared to porcelain-fused-to-metal?

On zirconia and lithium disilicate, the aggressive grit prevents clogging and maintains efficient cutting. On PFM crowns, they cut predictably through porcelain layers and reach underlying metal without excessive handpiece pressure.

How can I extend the life of an extra coarse diamond bur?

Although designed for durability, burs cutting through ceramics and metals experience high wear. Using proper irrigation to reduce heat and replacing burs before significant dulling will ensure consistent results and reduce chair time.

Are these burs compatible with all high-speed handpieces?

Yes. Most extra coarse grit diamond burs on Net32 use standard friction-grip shanks, making them universally compatible with high-speed handpieces. Always confirm size and shank type when ordering.

When should I use an extra coarse grit diamond bur instead of a medium or fine grit?

Extra coarse burs are best reserved for heavy reduction—such as removing zirconia crowns, bulk composite, or contouring ceramic restorations. They’re less suited for margin refinement, where finer grits provide better surface smoothness.

What bur shapes are most effective for crown removal?

Cylindrical or tapered burs with extra coarse grit are particularly efficient for sectioning crowns, while flame shapes allow access to interproximal areas without unnecessary reduction.

Extra coarse grit

Extra coarse diamond burs provide aggressive, reliable cutting power for demanding restorative and prosthodontic procedures. These burs are engineered for efficiency—removing dense materials such as zirconia, porcelain, and metal crowns with fewer passes and reduced chair time. For clinicians who value precision and durability under pressure, they offer a trusted solution for high-resistance cases.

At Net32, you’ll find a broad selection of extra coarse burs in multiple shapes and diameters to match your procedural needs—from crown and bridge removal to rapid bulk reduction. Compare leading brands, explore pack sizes, and source the instruments that align with your operatory’s workflow—all at competitive prices backed by vendor transparency.
