‘What is the difference between 1st and 2nd fix nailers?’ is a question commonly pitched to us. Thankfully, we can answer that for you. Not only that, but in using our Dewalt nailers as an example we can do so while checking out the features of both types.

The nailers we will be looking at in depth here are the DCN692 (1st fix) and DCN660 (2nd fix).

DCN660

Dewalt nailers

Firstly, the main differences between them. The DCN692 is designed for tasks such as joinery, roofing, fencing, flooring, studwork and wood framing among other 1st fix applications.

You will find this most effective when working outdoors on areas that aren’t likely to be on show once a job is finished. Don’t be concerned, therefore, if your DCN692 leaves debris in its wake; its large nails are primed to do exactly that.

Meanwhile, the DCN660 is primarily for completing ‘softer’ jobs. These include door frames, coving, architraves, skirting boards, household mouldings and general woodwork finishing.

The use of smaller nails ensures damage to the work area is reduced. In addition to that, with 2nd fix nailers you can also decide whether to use straight or angled nails. The latter are more popular as they are better equipped to navigate hard to reach areas.

DCN692 features

  • Benefit from longer runtime, quicker readiness to fire, less recoil and more durability when firing short nails
  • Class leading vibration and sound figures, offer fantastic user protection
  • Versatile 30 – 34 degree magazine angle will accept most clipped head, and off centre round head paper tape or wire weld collated framing nails
  • Reversable belt/rafter hook povides increased portability and versatility on the jobsite
  • Increased visibility and durability along with protection for work-surface from the non-mar contact-trip
  • Ergonomic tool design allows the nailer to fit easily between a 400mm centre stud
  • Gas free operation offers a significant saving in running costs
  • Cordless design allows you to work without the inconvenience and safety risk of trailing leads

Additionally, the ability to operate or two speeds/power levels optimizes the nailer for firing all lengths of nails, while its dry fire lockout function ensures that the tool is protected from firing without nails in the magazine.
