There are two different kinds of replacement inner shafts for discontinued Series H Motors. Be careful when ordering. Be sure to expose the entire inner shaft to determine which style you need:
1. The square drive shaft featured here has square drive tips on BOTH ENDS and no coupling. Use it with the S-10802A heavy duty outer sheath.
2. The S-10805 is the other style inner square drive shaft. It has a square drive tip on the handpiece end and a coupling on the other end for attaching to the motor. When used as replacement on a discontinued Series H motor (that uses this style shaft), it should be partnered with the S-10802A heavy duty sheath (which includes the SS10822 silencer spring). Depending on your needs, you may want to consider purchasing the S-10804B, which is a complete shaft/sheath/silencer assembly.
Square drive shafts can only be used with Foredom’s square drive handpieces. See related products below.
S-10805/45 Shaft MUST ship via UPS in larger carton to avoid damage (bending) that could occur if shipped in smaller, USPS carton.
