Badeco Swiss Hammer Handpiece 217 Medium Spring Strength-With Duplex Spring

134.751-217 Badeco 217 Medium Spring Strength-With USA Duplex Spring Attachment

Badeco Swiss Made Hammer Handpieces - The World's Best Hammer Handpiece

This is the USA version of the Badeco 217 medium spring strength hammer handpiece that includes the USA duplex spring attachment for added flexibility.

We also sell the Badeco 217 medium spring strength hammer handpiece in a non-duplex spring version as well as the Badeco 222 Heavy Strength version of this hammer handpiece in both duplex spring and non-duplex spring versions, (see below).

This handpiece connects to the North American standard QD key tip flex shaft found on Foredom and other flex shaft machines sold in North America. Adapters are available for converting this handpiece for European slip joint flex shafts (see below).

Genuine Swiss made Badeco hammer handpieces are recognized by stonesetters throughout the world as the best quality reciprocating hammer handpiece you can buy. Jewelers prefer the Swiss made Badeco hammer handpiece for its easily adjustable stroke, its controllable power and its long service life. You must run this device using a Low Speed High Torque Foredom motor item 134.159. This will extend the life of the duplex spring. Remember the pedal controls speed not power.
Most setters prefer the model 222 heavy spring-but we do have setters that prefer the medium spring 217-especially if they work on delicate stones exclusively.

This handpieces includes a Badeco 137.753 (Badeco 240.000) non-hardened tip. This tip is meant to be shaped and hardened by the user. Factory instructions for preparing the tip for use are as follows:

Shape the tip as you wish.

Step 1 Hardening. Hold piece on thread part with tweezers. (Caution: do not damage the thread!). Heat up front part with blowlamp up to 820 degrees centigrade (=light cherry-red). Cool down rapidly, putting tip head down into oil bath.
Step 2 To remove oil, whiten with thin sand paper. Do not touch point with your fingers!
Step 3 Tempering. Finally, pass piece from back to front over blowlamp up to 130 degrees centigrade (the color of the piece must not change!) and cool immediately in oil bath. Should the temperature be too high, tip will lose its edge rapidly on first utilization. In that case start the whole process again beginning with Step 1.

A wide variety of pre-shaped and hardened tips are available separately (see below)

Please note that Badeco has a one year factory warranty. This warranty does not cover the American made duplex spring, which has no warranty. Duplex springs add flexibility, but can be easily damaged if misused. Do not exceed a 45 degree angle when utilizing the duplex spring. Please carefully read the owners sheet that is included with every Badeco hammer handpiece we sell for proper use and limitations. The factory states the warranty as such:

Repairs caused by faulty material or workmanship will be rectified at no charge by the manufacturer within one year of invoice date. During the warranty period, all pieces dismantled by the user will be repaired at user's expense. Repairs effected due to wrong utilization and non-observance of our (Badeco) instructions will not be done under warranty.

Otto Frei has a repair department that can repair Badeco hammer handpieces.

Before choosing this duplex spring model please read the following: Duplex springs are not made by Badeco and are attached post factory. Duplex springs, and all parts related to the USA made duplex spring connections, have no warranty. Duplex springs should not be bent beyond 45 degrees during use! Duplex springs can be damaged easily if operated beyond the 45 degree angle or during detaching the handpiece from the end of the flex shaft. Duplex springs can also fail during normal use. If you choose a duplex spring model, you may want to purchase additional inner duplex springs (Single piece part number 134.279 Foredom HP76-Pack of 12 part number 134.280 Foredom HP76B) and learn how to change out and replace the inner duplex spring, the most common part that can fail.
