Frequently Asked Questions
Which mills are these diamond burs compatible with?
They are compatible with Amann Girrbach Ceramill milling units that grind glass ceramics. Match the diameter to the tool position in your Ceramill strategy.
Are these original Amann Girrbach burs?
No. These are Eagle-brand diamond milling burs made to be compatible with Ceramill mills. They are not original Amann Girrbach tools.
What materials can I mill with them?
They are made for E.max and other lithium disilicate and glass ceramic blocks.
Can I use these burs for zirconia?
No. For zirconia, use CVD diamond-coated zirconia milling burs. These diamond grinding burs are made for glass ceramics.
How many burs are in a pack?
Each pack contains 5 burs of the size you select.
Which size should I order?
Order the diameter of the worn tool position: 0.4 mm for the finest detail, 1.0 mm for detail finishing, 1.4 mm for general finishing and 1.8 mm for roughing.
Should I grind E.max wet or dry?
Glass ceramics and lithium disilicate are ground wet, with coolant. Use the wet strategy your Ceramill unit and block manufacturer recommend.
How long do diamond milling burs last?
There is no fixed number of units. Bur life depends on the block type, restoration size, strategy and coolant condition. Track usage in your software and watch for signs of wear.
Why are my E.max crowns chipping at the margins?
Common bur-related causes are a worn fine-detail bur or low or dirty coolant. Replace the worn bur, check the coolant and, if the problem continues, calibrate the machine.
Do you ship worldwide?
Yes. We ship worldwide, and express shipping is available.
