RAY FOSTER Model F035 — High-Speed Automatic Spindle For Demco E-96 & B-1
OEM FOSTER spindle For Demco grinders — B-1 mounting tubes included, no separate adapter needed
RAY FOSTER Dental Equipment has manufactured precision dental laboratory products in Southern California since 1938. The FOSTER precision High-Speed Automatic Spindle is the original mechanism — designed For heavy-duty continuous operation.

Key Selling Points
- The FOSTER-quality upgrade For Demco-equipped labs

- Field-serviceable design — technicians can rebuild rather than replace
What Makes This Unique
Demco E-96 and B-1 are the workhorses of countless European and Asian labs. The factory Demco spindle works, but the FOSTER F035 is the precision upgrade that retrofits cleanly — including the B-1 mounting tubes, which historically required separate sourcing.
💡 Selling Tips For Sales Team
- The Demco upgrade pitch. Most Demco labs accept their OEM spindle as "good enough." The F035 is what they'd buy if they knew the difference. Lead with the smoothness/precision story.
- B-1 mounting tubes included. Specifically call this out — B-1 owners are used to hunting For adapters separately.
- Don't confuse with F030/F031. F030 = AG04/Whip Mix/CF Price. F031 = AG03/AG05. F035 = Demco E-96 and B-1 only.
- Pair with collets. The F112 collet set is specifically sized For the F035.
- Made in USA. Especially relevant For international Demco labs upgrading to American precision.
