In my workshop I have drills up to 30mm ,I just keep the micros for modelling . My scalpels are no 4 handle with no 22 and 24 blades ,no 3 handle with no 11 blade. I have a panel line scriber I bought from NKR Models here in Australia .I don't know who made it but it is a very good one. Not sure if he still has them. I bought some dental burrs on Ebay , I'm yet to try them with the mimimotor tool, I also got some dental reamers these are similar to a twist drill and very sharp. Scalpel blades I get in packs of 100 ,out of date as far as sterility goes ,but good for modelling.
