Throw away your compressor...
The M18 Fuel 15 gauge finish nailer is just as good or better than my pneumatics. Better actually, because I don't have to trip over my hose. Last week I installed 100 sheets of 3/4" marine grade plywood coated with epoxy paint shooting 2-1/2" 15 gauge nails and I went through one 5.0 XC battery a day. I didn't have any problems with shiners or penetration and my co-workers who used it were blown away. Today I made a custom door fastened with inch and a quarter 15 gauge nails. I own the M18 Fuel - 18 gauge finish nailer too, and it is just as good. I look forward to Milwaukee's release of their framing nailer and then I will finally be rid of my compressor.

Great power. No hang ups or jams. It’s a little heavy and bulky. You won’t miss your air compressor with this nail gun.

Not what I’ve come to expect from Milwaukee. Heavy, awkward and cumbersome to use. You hand and wrist will hurt after using.

I am so glad that Milwaukee made this tool!!!
I am using this tool as a time saver during remodeling of several rooms. It does not disappoint, fits right into my arsenal of M18 tools perfectly, cost effectively by using my existing batteries and chargers. This is a functioning home and remodeling is disruptive. Not dragging cords and air hoses into the mix is such a big help! The speed and ease of trim install or quick tacking of other items when working alone is just unbeatable. Makes it seem like I hardly use the nailer because it is so fast compared to the positioning, hammering, and setting of nails the old way or getting out the compressor, getting out the air hose, getting out the extension cord when using an air nailer. This nailer is just unbeatable and fun instead of a chore, I love it!

Saves time not having to hook up a hose and compressor. Great to be able to use belt clip as well while on a ladder and not set it down and watch to make sure not to knock it off. The adjuster for nail depth is down at the tip of the gun and is very easy to adjust. The battery lasts all day while installing trim around the windows. Great product.

Better than I expected.
Final stages of building a new house and needed a finish gun. I have a plethora of the black and red so I thought I would try the 15g finish gun. To my surprise it shot through the pine trim with 2" and had zero jams. I then installed custom closet shelving and again had no issues. It is a little on the heavy side, however not having to drag a hose around is worth the weight. Now to convince my book keeper/wifethat I need the 18g gun.. lol.

This thing Rocks!!!
This is by far one of my favorite tools. I was hesitant to purchase because of the delay that happens when trigger pulled and nail shot...this tool has NO delay!!! You pull the trigger and it is instant shoot. No air hose to drag around....Great Job on a tool well made!

High quality product
Since purchasing the nailer I have used it several times. It has been dependable with no slip ups. It has not jammed at all like my old passlode gun used to. I only wish it came with a hard case which is why I didn't give it 5 stars.

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 120 days.
