Zirconia milling burs
Zirconia burs cut the material most laboratories mill most, and the source catalogue lists zirconia milling burs as a category with several listings, including a VHF 2.0mm zirconia bur on a company home page. The VHF name appears there as a third-party system reference, telling a laboratory which system the bur listing is associated with, and this site keeps it in that role only. A buyer choosing a zirconia bur should name the holder and the milling machine it must fit, because those two facts decide compatibility more than any catalogue description.
Zirconia burs also wear, and a laboratory should think about bur life as a consumable cost rather than as a one-time purchase. A laboratory that needs a bur life figure should ask for it in an inquiry, naming the bur, the material and the machine. The answer can then be judged against the laboratory's own milling volume, which is the figure that actually determines how long a bur lasts.
Ceramic glass milling burs
Ceramic glass burs cut glass ceramic and lithium disilicate, materials that need a different bur approach from zirconia because of their brittleness and their translucency requirements. The source catalogue lists ceramic glass milling burs as a category, with listings that include a Cerec inlab bur for lithium disilicate on a company home page. The Cerec name appears there as a third-party system reference, and this site keeps it in that role only, not as a company brand or partnership.
A laboratory milling glass ceramic should confirm the bur against the material and the machine together, because a bur that suits zirconia may chip a glass ceramic piece, and a bur that suits glass ceramic may wear too fast on zirconia. The bur selection guide compares the categories in general terms, and it points those compatibility questions to an inquiry, where the laboratory can name the material, the holder and the machine in one message.
PMMA milling burs
PMMA burs cut provisional and prototype material, where the cutting problem is different again: PMMA is softer than zirconia or glass ceramic, and the bur must clear chips cleanly rather than fight hardness. The company catalogue lists PMMA milling burs as a category, described here in those terms. Ask for their specification table in an inquiry. A laboratory milling PMMA provisionals should name the PMMA disc or block in use when asking about a bur, because the disc and the bur work as a pair.
PMMA milling also produces dust that extraction must clear, and the vacuum cleaner page describes a dust extraction system listed for zirconia milling equipment, which a laboratory should ask about alongside a PMMA bur order if it mills PMMA on the same machine. That combined question lets the company answer the setup rather than the bur alone, and it avoids a bur that fits but an extraction unit that does not match the machine's connection.
Metal milling burs
Metal burs cut the hardest materials in the laboratory, and the source catalogue lists metal milling burs as a category beside the other three. Metal milling needs a bur, a coolant or lubrication approach, and a machine rigidity that the other materials do not, and a laboratory moving into metal work should discuss those points before ordering. This page does not prescribe a bur or a cutting parameter for metal, because those depend on the metal, the case and the laboratory's existing setup.
The RX-8H metal milling machine page is the natural companion to this section, because a metal bur is chosen for a metal machine as much as for a metal material. A laboratory ordering metal burs should name the metal, the machine and the holder together, and the company can then confirm the bur that matches that combination. A message that names only the bur, without the metal or the machine, will need a second round of questions before it can be answered.
Third-party names, kept in their place
Three third-party names appear across the burs listings: VHF on zirconia and wet milling bur listings, Cerec on a lithium disilicate bur listing, and Amann Girrbach on a series of bur listings on a platform page. Each appears in the source listings as a system or brand reference for compatibility, and this site keeps each one in exactly that role. No page on this site presents any of them as a company brand, a partner or an endorsement.
That discipline protects the buyer as well as the company. A laboratory that reads a third-party name as a partnership might assume a compatibility guarantee that was never given, while a laboratory that reads it as a compatibility hint will confirm the fit in an inquiry and get a specific answer. The inquiry form has room to name the third-party system, the holder and the machine together, and that message is the right place to turn a hint into a confirmation.
How to order milling burs
An order should name the bur category by milled material, the holder or system it must fit, the milling machine it will run on, and the quantity range, and then confirm the minimum order quantity, lead time, shipping method and payment terms as buyer instructions. Those four confirmations vary by order and destination, and this site does not promise them in advance. A laboratory that orders burs regularly should also note its repeat pattern, so the company can advise on availability for repeat orders.
A first order of a small quantity for testing is sensible for a bur the laboratory has not used before, because fit and cutting behaviour can be checked on a single case before the bur becomes a regular stock item. The inquiry form has room to describe that test plan, and a company that knows it is a test order can advise on the bur choice that will make the test most informative. The form asks only for a name, an email address and the message.
