Using any kind of impact tool (including drill drivers, combi-drills, impact screwdrivers, impact wrenches, hammer drills, etc) will invalidate your fixings warranty.

Sure, they might self-drill and tap on many occasions and all might seem fine but it causes irreversible damage to the threads that wouldn't occur with a non-impacting tool.

Kingspan Insulated Panels UK & Ireland Technical Update EU105 and NFRC Guidance Note GN01 both highlight the negative effects of impact tooling and why the use of these tools is prohibited.

Use the right tool and the right methodology!
