Shafts and Sheaths

Most current and discontinued motors use our Standard S-93 Key Tip Inner Shaft and S-77 Outer Sheath that work with all of our interchangeable handpieces. When motors come equipped with Square Drive shafts and sheaths (shown in video thumbnail above) they are considered 'Heavy Duty' and have the letter 'H' (Series SRH, TXH, LXH). Heavy Duty shafting is stiffer and less versatile since it works ONLY with our four square drive style handpieces. Most applications do NOT require heavy duty shafting. Non-Conductive versions of key tip and square drive shafting are also available. They have plastic connectors in place of our metal ones that prevent stray electricity from traveling down into the handpiece. Slip Joint shafts and sheaths are specialized and used to convert Foredom motors into European models that work only with slip joint type handpieces.

Most users replace worn or broken shafts and sheaths with exactly the same kind that came on their motor, however, it is possible to switch from one style to another. For example, an M.SR motor with Key Tip shafting can be converted to a heavy duty model by installing a square drive shaft and heavy duty sheath (plus motor connector). The reverse also applies. Heavy duty models with square drive shafting can be converted into standard models with key tip shafts and sheaths. There are exceptions to this, so be sure to watch the video material and read product details.
