Swiss-type (sliding headstock) lathes hold their tooling in fixed positions on a gang or comb layout rather than in a rotating turret. Each position is machine-specific: the holder body, the mounting face and the drive coupling are defined by the machine builder, which is why a Swiss-type holder is identified by the builder's own reference code rather than by a BMT or VDI size.
33150 is a driven position — the tool spindle turns at 1:1 to the machine's live-tool drive, up to 8,000 rpm. Usable speed is whichever is lower: this rating or your machine's drive rating.
Mongtec supplies 33150 to the Star reference 33150, so it occupies the same holder position on the machine. That reference is the fastest way to specify what you need: quote the code from your machine's tooling list and Mongtec engineering matches it, then confirms the fit against your actual machine and station before quoting.
Star is a registered trademark of its respective owner. Mongtec Precision is an independent tooling brand with no affiliation to, endorsement by or licence from Star. The Star reference code is quoted only to identify which holder position and machine the Mongtec part is built for; fit is confirmed by Mongtec engineering at RFQ.

Send my machine and get the article number →33150 is built to the Star reference 33150 for Star Swiss-type (sliding headstock) lathes. Holder positions differ between machine generations, so send Mongtec your machine model and the station you want to use and engineering confirms the fit before quoting.
Mongtec supplies 33150 to the Star reference so that it occupies the same holder position. Mongtec is an independent tooling brand and is not affiliated with Star; interchange in your specific machine and setup is confirmed by Mongtec engineering at RFQ.
33150 takes tools up to 10.0 mm using ER16 collets, on a 34 mm holder shank. Collets are supplied separately — tell Mongtec the shank diameters you intend to run and they are quoted with the holder.
Send the machine model, the station you want to use and the tools you intend to run. Anything you do not know, Mongtec works out from the machine model — an incomplete enquiry is still worth sending. Dimensioned drawings are supplied by email once the enquiry is open.
