Senco DS440-AC 3 in. Attachment Kit with 4,000 RPM Screwdriver

It is a good help with the job and reduced my time by at least half. I choose the power cord rather than electric because I didn’t want to stop due to the batter. A few times the screws jammed, but it was easy to unjammed it.

It came on time it works just fine for me

The is great for putting down deck boards. Not enough instructions for putting it together.

This thing is awesome. It makes the job of installing underlayment and hardi backer so much easier. Every now and then it will misfire(drop a screw on the floor instead of driving into the floor) it’s but it’s no big deal compared to crawling around and putting screws one at a time with a regular drill.

This thing is is great. I ran 1000 screws in a floor in a couple hrs. would have taken 2 days on my knees. I had fun using this new toy. Ran out of screws, Darn it. Can’t wait to get more. Needs longer ammo belt like the old M60 I carried a few decades ago.

a real back and time saver

I was building an addition that has tongue and groove sub-floor and thought that this tool would be a back saver. All I can say is why didn’t I get this sooner? I have built and remodeled five homes, let alone the fences I built, and this would of saved me soo much time. The tool is very easy to setup and use. I screwed in a 4×8 sheet of sub-floor in 1/3 of the time, at least, if I had to use a standard driver and screws. The screws are more expensive, but the ease and speed make up for the additional cost. It comes in a very nice bag, but because of the shape of the tool, a little cumbersome to store. A few things about the tool now that I have installed 400 sq feet of sub-floor, 1000 sq ft of sheathing, and 120 sq ft of decking:1. If you go on an angle, sometimes the screw will not go completely in. For example, your sheathing only has 1/4″ of 2×4 available, I would hand screw the screws.2. The forward/reverse button isn’t in the best location. When I was loading up the screws, I accidentally knocked it into reverse. I didn’t know it and was freaking out because the screws weren’t going in.Besides those minor items, a superior product and a must have for any serious DIYer or has a large project (i.e., new deck, fence, etc.)

i really enjoyed this purchase , it made redoing my deck a breeze . no back aches or knee aches .

Works great. Just like I wanted. It does seem to skip screws every now and again. Might be my technique….

Once I got it set up it works amazing. Wish I would have bought it years ago. Saves time = $.
