Notes
Important usage requirements for Duplex spring models:
- Duplex springs must not be bent beyond 45 degrees during use. Operating beyond this angle or during handpiece detachment can cause damage.
- Do not operate above 5,000 RPM. Use of a Foredom LX hi-torque, low-speed flex shaft motor is recommended.
- Duplex springs can fail during normal use. Consider purchasing replacement inner duplex springs and learning how to replace them — the inner spring is the most common part to fail.
- Replacement inner duplex springs are available: single piece Part #134.279 (Foredom HP76) or pack of 12 Part #134.280 (Foredom HP76B).
- The 60-day handpiece warranty does not cover the Duplex spring attachment or any related Duplex spring components — these carry no warranty.
- Cannot be operated in reverse.

I love the Swiss Technique handpieces and I thought this would be a match made in heaven for me.
This is a total buyer beware situation! This sees part time use on my shop and just completely failed on June 2nd. I ordered the part on April 26th and have used it for a month. PLEASE READ THE DISCLAIMER!!! Otto Frei obviously is aware of the situation and continues to sell this product. I have other duplex spring handpieces I have used for YEARS without problem and to have it fail within 30 days is beyond disappointing and frustrating!
I really hope to have a productive conversation with Otto Frei customer service, but based on re-reading the item description I won't hold my breath. Save your money and look for another solution for your shop needs.

I just wanted to share our experince with this. Since the only review seems to be of a defective combo. We absolutley love the technique handpieces. Tried all the Foredom ones, Faro and finally got our hands on a technique and havent looked back. Each bench has two, one with a duplex spring and one wihtout. We have had our oldest ones running with daily use for about 6 years, the second set for four years and we just purchased a third set of hand pieces for our newest jewlry bench. Its unfortunate that the other reviewer had a bad experince, these are the best!
