Zirkonzahn M5 Heavy Metal Compatible Dental Milling Burs

Zirkonzahn M5 Heavy Metal Compatible Dental Milling Burs

Milling burs for the Zirkonzahn M5 Heavy Metal, cut to the same tip geometry and shank tolerance as the OEM tool set. Used for zirconia, PMMA, wax and metal on heavy-metal models in the machine's standard wet and dry variants per model cycle. Mounting: 3 mm shank typical.

Bur selection on the Zirkonzahn M5 Heavy Metal

• Roughing pass: larger tip diameter for fast material removal on zirconia, PMMA, wax and metal on heavy-metal models
• Semi-finish pass: medium diameter for axial walls
• Finish pass: small diameter for detail and margin
• Shank: 3 mm shank typical for direct OEM replacement

Tool life notes

Keep a simple log (job count per bur, material, any margin issues) and the pattern becomes obvious within a week or two. Most early tool failures are feed/speed or coolant issues, not bur quality - sudden chipping usually means the collet is loose or the spindle TIR has drifted, not that the bur is defective.

Support

If the first bur you order does not drop straight into the Zirkonzahn M5 Heavy Metal tool changer, contact us with a photo of the OEM bur alongside ours and we will confirm whether it is a shank-mismatch issue or something else. We would rather get the spec right before a second order than have you run a partial batch with the wrong tool.
