This is very much a specialist professional nailer, sometimes known as a "Powder Actuated Tool" or "PAT" or generically known as a "Hilti Gun" or a "Ramset Gun" should you opt for the versions which utilise explosive cartridges. These nailers are also now available in gas-fired or, more recently, battery-only (gas-free) powered versions.

These nailers are used in construction applications where there is a need to fix hard materials such as steel to substrates such as masonry or concrete. Widespread uses would be tasks such as setting metal stud wall frames to concrete or hanging electrical trunking from pre-cast concrete.

Standard nail sizes range from around 25mm to 100mm but come in wide varieties to suit many applications and will vary depending on the material you want to fire through or into.
