Does your DX350 Hilti powder actuated tool not work. Was it dropped and can you see a visible indentation on the bud end of the tool next to the rubber grip. If the tool will not shoot oftentimes if it has been dropped the housing is pressed against the firing pin on the inside of the housing and it is a very technical fix trying to round out the backend of the tool again. Here is your solution. This is a housing for an operational DX350 with everything intact, firing pin, trigger mechanism, detent, detent sleeve, firing pin springs, everything that you need to get your tool up and running again. If you look at the photo you can see it even has the steel ball that goes in the front end. All you will need to do is take the annular spring off of your tool take the stop off of your tool and replace it in the front end of your of this new tool housing with everything intact. It's a fast easy solution with minimal expense compared to buying a new powder actuated tool from Hilti.
If you're kind of cheap like I am you don't want to buy a new $1,000 tool if you're on the tail end of your career or you only have an occasional use for this powder actuated tool. This is a great solution for anybody wanting to keep their tool up and running without the expense of factory parts. Hilty does not support the DX350 either.
Thanks for looking and if you move forward thank you for your business.
