Protool did have 2 Impact drivers called IDC15-2 and IWC18-2.
They were discontinued before the PDC/DRC models were converted to Festool models.
Why they stopped selling it I don't know.
The 14,4V range of Protool has been discontinued a 1-2 years back already. That I also don't understand.
While the IWC18-2 model was even upgraded tot the latest models.
