Milwaukee 7155 21 3/8 Inch to 1 1/2 Inch 18 Gauge Narrow Crown Stapler

Editorial Review
The Milwaukee 18 gauge 1/4" Narrow Crown Stapler features an ultra lightweight magnesium housing that helps to minimize fatigue, plus its compact size offers greater maneuverability. This tool features a powerful oil-free motor that eliminates daily oiling and potential work surface contamination. The tool-free depth-of-drive adjustment gives you precise depth control and protects against overdriving nails. This unit also features a selectable trigger that allows you to choose sequential or contact actuation by simply turning a knob. An in-handle self-cleaning air filter extends life by preventing dirt and debris from entering the tool. The adjustable air deflector with muffler directs exhaust away from the work area. This nailer comes with a removable no-mar tip that prevents damage to the workpiece. It also features a reload indicator that alerts the user when nearly out of nails. Also features an internal piston catch, rubber over-molded handle and trigger, and an adjustable belt hook that provides convenience for carrying when not in use.

light weight but hard hitting

2007-12-30
I havnt used it much but wen I did it set the 1 1/2" staples in MDF and pine with no problem. I found the safety to be a hinderance in detailed mouldings, I forced it back with a shim and works much better now. It still sticks out 1/8" I tried to hacksaw it off but it must be hardend, a friend suggested I use the belt sander. I had an old pasload that bit the dust and it was much heavier than this tool. I luv the light weight and the color. If I can eliminate this saftey and it performs in the hardwoods I will be a happy camper.

Great gun over all!

I bought this gun to put cabinet drawer boxes together.
The GOOD is-
I really liked it from the box. It is nice and light with a really cool belt clip. That would have never sold me on the gun, but now that I have a belt clip - I am looking for a finish nailer with one (it must have one)! It helps if you put a swivel hose nozle on the gun so it doesn't fall off your belt as easy.
This gun has a small profile and simply feels nice. The knob that allows you to control the depth clicks as you turn it (which is just plane nice again, not a feature that would sell me on the gun).
It also will not fire when it is out of staples, so it doesn't make an uneccesary hole.

The BAD points are few, and maybe undetected. I have been buying less expensive guns in the past, like porta-cable. When they broke, I tore into it to find that it has a plastic cylinder. Is that what this gun has?? The safety tip has bent out a little, which can be a big inconvenience when you are trying to shoot near an edge. The tip will not contact your material, and therefore prevent you from firing. Also, there is no indicator of your staple supply.
So far, I would still buy this gun again!

You Get What You Pay For....

As a pneumatic neophyte I found the 7140-21 very easy to load and use. Worked perfectly right out of the box without any depth adjustments. Quality and durability are important to me so I was willing to spend a little more. I wouldn't hesitate to buy another Milwaukee tool in the future. You supply your own NPT adapter so make sure you have it on hand so you can begin using this tool immediately.

milwaukee narrow crown stapler

Awesome product. It't lightweight, easy to manuever, easy to load and I never had a misfire or stuck staple yet. Well worth the money.

Lightweight Finish Stapler

2006-08-18
I just purchased this stapler to install cedar siding and it worked great. Using 1 1/2 long staples it had no problem going through the siding, 3/4 plywood and into the 2 x 4 studs. This unit comes in a nice plastic case with with metal clasps. This stapler is light and easy to use. Note this unit does not come with a fitting so have one on hand if you need to use it right away.

Two small gripes - otherwise a good deal

This Milwaukee stapler has worked pretty well and has saved me a lot of work. A far cry from having to use a manual stapler. I do have two minor complaints. The first is that mine did not come with the anti-mar piece that fits over the actuation plunger. This would help to minimize the amount of surface marks on the finished product. The second issue is that when using the smaller sized staples - 3/8" and 1/2" - it will occasionally misfire. It doesn't jam - just no staple is fired. The next one may be fine, or it may take two or three tries. Then it is back to normal. I have been using only brand name staples, so can't imagine that is the issue. Even with this irritation, I would never go back to doing it the old way.

Great price for a great stapler

2008-06-18
This stapler costs significantly less than comparable tools at the brick and mortars. So I was a little hesitant to purchase it. After all, Milwaukee's claim to fame is the Sawzall, not air tools.
But I took a shot and I'm glad I did. This stapler is very light weight but it just feels so solid and well-built.
The attached built clip is a nice touch as well. I've used it in a project already re-screening my back porch and I'm looking forward to the next project that requires a stapler.
I have a new-found respect for Milwaukee tools after this purchase.

Excellent gun and value

2008-03-28
Nice little quality gun! Now has me raising some eyebrows to other Milwaukee guns. Would absolutely buy again.

Good value

2008-03-24
I've had half a dozen narrow crown staplers and worn them all out. I've used this one a few times now and have been pleased. One nice feature is that it stops sending the plunger down when it runs out of staples. The price was right and the stapler seems like a good one.

Nice little gun

2008-01-07
This seems to be a pretty sweet little gun. I am a contractor and just wanted to find a rebuild kit for my senco gun. Saw this low priced gun and thought I would take a chance on it. I needed to staple a lot of Redwood slats for a Japanese style fence. The gun worked perfectly. I really liked the depth of drive adjustment. For underlayment you will probably want a heavier duty gun.
