1. Is this a genuine Bergeon original tool?
Yes. This is a Swiss Bergeon factory‑original product, model 7902‑HO, brand new in original packaging – not a counterfeit.
2. Does the set include a handle?
No. This set contains only the 5 quick adapters and tips. It requires a Bergeon 7902 series handle (e.g., 7902, 7902‑S) which is sold separately.
3. Are the tips prone to wear or breakage?
The tips are made of hardened stainless steel with professional heat treatment (approx. 61 HRC), offering excellent hardness and toughness. Under normal use, they remain sharp and durable. Regular cleaning and correct fit with screw slots is recommended.
4. Can the tips be replaced individually or purchased as spares?
Yes. Bergeon offers replacement tips and spare blades for the 7902 system (e.g., 6899‑T series), available separately for long‑term maintenance.
5. Are these adapters compatible with handles from other brands?
These adapters are specifically designed for the Bergeon 7902 series handle. Compatibility with other brands cannot be guaranteed. For best performance and safety, we recommend using the original Bergeon 7902 handle.
