For milling PMMA or wax. Total length 40mm. 

P250-F1-40
2.5mm can be added for increased efficiency at the beginning of the milling job, when the machine must quickly remove larger amounts of material.

P200-R1-40 | P100-R1-40
2mm and 1mm are needed no matter what you are milling. Used for the majority of the milling job and need to be changed more often than 0.6mm and 1.2mm.

U120-F2-40
1.2mm is needed for many implant designs. It has a flat profile (see picture), which allows it to mill out sharp corners.

U060-R2-40
0.6mm is needed for fissures (full anatomy), for certain rotational locks and to better separate joints, etc.

For milling exceptionally fine details in PMMA, wax or zirconia, you can add the special tools.
