Frequently asked questions
Which consumables does this grinder use?
It takes the Ø165 diamond cup wheels with a clover bore, plus the velcro and ceramic pads in the range. The wheel to choose depends on the material to grind (concrete, render, resin, epoxy) and how aggressive you need it.
How do you maintain a brushless grinder day to day?
The brushless motor has no carbon brushes to replace, so maintenance stays light. Clean the housing and the extraction port after each shift and check the wheel is properly fitted.
Does the grinder capture dust at the source?
Yes, it is built for capture at source and pairs with a class H vacuum for silica or asbestos dust. Source capture keeps the jobsite cleaner and protects the operator.
What is the delivery lead time for Petit Potam?
We confirm the dispatch lead time with your quote within one working day: it depends on the model and workshop availability.
Why is the price on request?
Because a machine alone is not a workstation: the price depends on the configuration, the trolley or gantry, the extraction unit and the consumables matched to your substrate. A headline price would have you compare setups that are not comparable. Our machines do cost more to buy than an entry-level brushed machine, and we own that: the maths works over service life, not over the ticket. You are free to ask for a quote just to compare, with no sales follow-up if you do not take it further.
What warranty and after-sales come with Petit Potam?
Sept Tools machines carry a 24-month warranty, parts and labour. A tool from another manufacturer supplied with a set remains covered by its own manufacturer's warranty. After-sales is handled in our Roanne workshop, with a diagnostic reply within 48 business hours, no call centre.
