Frequently asked questions
Which consumables does this grinder use?
It takes the Ø165 diamond cup wheels with a daisy bore (also compatible with a 22.2 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 Tapir?
We confirm the dispatch lead time with your quote within 24 business hours: it depends on the model and workshop availability. Common spare parts and consumables are kept in stock in Roanne so your jobsite is not held up.
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 Tapir?
The whole range carries a 24-month warranty, parts and labour. After-sales is handled in our Roanne workshop, with spare parts in stock and a reply within 24 business hours, no call centre.
