1. Is this a genuine Bergeon product?
Yes. It is a Swiss Bergeon factory-original model 30543-AP, brand new in original packaging.
2. What is the difference between smoothing broaches and cutting broaches?
Cutting broaches (e.g., Bergeon 3008 series) enlarge holes by removing material. Smoothing broaches (this set) do not remove significant material; they burnish and work-harden the hole wall for a smooth, low‑friction finish.
3. How do I choose the correct broach size?
First use a cutting broach to enlarge the hole slightly under the target size. Then select a smoothing broach slightly larger than the current hole diameter and pass it through gently. Repeat until the desired finish is achieved.
4. Is lubrication needed during use?
A small amount of watch oil or dedicated broach lubricant is recommended to reduce friction, improve finish, and extend tool life.
5. How do I clean and store the broaches?
Wipe clean with a soft cloth after use, apply a light anti‑rust oil, and store in a dry place. Protect the tips from impact.
