Badeco Swiss Hammer Handpiece-222 Heavy Spring Strength-with Duplex Spring

The Badeco 222 Heavy Spring Strength Hammer Handpiece with USA Duplex Spring (Part #134.751) is a world-renowned Swiss-made reciprocating hammer handpiece trusted by professional stonesetters and jewelers worldwide. This is the USA version of the Badeco 222, configured with the American-made duplex spring attachment for added flexibility in tight or angled working positions.

Genuine Swiss-made Badeco hammer handpieces are recognized globally as the highest-quality reciprocating hammer handpieces available. Jewelers prize them for their easily adjustable stroke, controllable power, and exceptional service life. The Model 222 heavy spring strength is the most popular spring strength sold worldwide and is the preferred choice among professional stonesetters.

This handpiece ships with a Badeco 134.753 (Badeco 240.000) non-hardened tip, which is designed to be shaped and hardened by the user according to their specific setting needs.

Tip Preparation Instructions

1. Shape the tip as desired before hardening.
2. Step 1 – Hardening: Hold the tip at the threaded part with tweezers (do not damage the thread). Heat the front part with a blowlamp to 820°C (light cherry-red). Cool rapidly by placing the tip head-down into an oil bath.
3. Step 2 – Remove Oil: Whiten with fine sandpaper. Do not touch the point with bare fingers.
4. Step 3 – Tempering: Pass the piece from back to front over a blowlamp to 130°C (the color must not change). Cool immediately in an oil bath. If temperature is too high, the tip will lose its edge quickly — repeat from Step 1.

A wide variety of pre-shaped and hardened tips are available separately.

Notes

• Otto Frei recommends pairing this duplex spring model with a Low Speed High Torque Foredom LX motor (item 134.159) to extend duplex spring life. The foot pedal controls speed, not power.
• Do not exceed a 45-degree angle when using the duplex spring. Operating beyond this angle or during detachment from the flex shaft can easily damage the spring.
• Do not operate above 5,000 RPM. Duplex springs can be damaged at higher speeds and may also fail during normal use.
• The duplex spring is not made by Badeco and carries no factory warranty. All parts related to the USA duplex spring connection are also excluded from warranty.
• Consider purchasing additional inner duplex springs (single: Part #134.279 Foredom HP76; pack of 12: Part #134.280 Foredom HP76B) and learning to replace the inner duplex spring, the most commonly failing component.
• Handpieces dismantled by the user during the warranty period will be repaired at the user's expense. Damage from improper use or failure to follow Badeco instructions is not covered under warranty.
• Otto Frei offers in-house repair services for Badeco hammer handpieces.
• An owner's instruction sheet is included with every Badeco hammer handpiece — read carefully before use.
