good price
love the 18 gauge in certain situations where my 16 gauge made holes that I felt were too big. Lightweight, easy to use, but especially like the price.

Great nail gun!!
This nail gun does a great job! Works great on smaller trim. I used it for hours without a single jam. I also bought the 15ga Bostitch nailer. I've used several other brands of nail guns and this is by far one of the best.

First Bostitch nailer for me
I had to replace baseboards after flood and add shoe molding after floating floor installed. The molding is 55-60 years old so no modern replacement so was patched with tablesaw made and looked good. Needed to use 2 in. brads with shoe to reach the baseplate. The nailer worked very nicely on the single-shot setting for the oak material, countersinking the head perfectly with 100 psi pressure in Porter Cable compressor. It was actually very pleasant to use with no misfires or jams. Got it for the oil-free feature. Very light and easily positioned at odd angles Recommend highly.

For casual home users the oil-free is great. Two of my friends terminated their nailers by forgetting oil for the older nailers.By the way the trigger lock and single/mutiple shot locks are easy and effective in use, again for us amateurs.

$50 pencil sharpener
I work as a professional finish carpenter and used this tool every day for three weeks, with much satisfaction until the driver unit jammed. Tyler Tool accepted the return and sent another refurbished nailer. However, the second gun had problems from the start. Upon pulling the trigger it simply blows air and refuses to drive a nail. A coworker has the same gun, uses it frequently, and has not had a problem. My experience can easily be an anomaly, but I will have nothing to do with this model gun again. My coworkers now refer to the gun as the $50 Pencil Sharpener. For infrequent use around your house, this gun is probably worth the money. But if you are looking for a gun to last a decade or more, spend some more cash on a Senco product.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
