Questions & Answers


what's the difference?

Asked by Mike September 10, 2018

There are over 10 different models/combo kits to choose from, but if you are specifically referring to the 3-in-1 models: 1. Model# SXL31, on the surface, appears to be just a newer version of the SL31, but thes SXL31 allows a max 2.5 inch fastener, 2. Model# SL31, allows a maximum of 2.0 inch fastener.

How much does it weight.

Asked by Lynn July 16, 2018

3-5 lbs

will this product work well to staple cedar shingle siding?

Asked by Ted November 24, 2017

I don't see why not. Get familiar with its operation first and use some scrap to set your depth or you could leave pick marks on your finished surface.

Will this do the First few rows of hardwood flooring? 3/4 thickness

Asked by Nofingerprintssleek March 26, 2017

Yes, you can nail through the top of the first row of flooring against the wall where the hole will be covered up by trim. Second and third rows, if necessary, would be a little more difficult because you will need to nail into the correct spot in the tongue of the flooring, at the correct angle, most likely with the 18ga narrow crown staples. Refer to the flooring manufacturers installation instructions before doing any nailing to make sure you don't void their warranty by using the incorrect fastener.

Does it come with a case and is it oil free?

Asked by Rich March 24, 2017

No case for the one I bought. Oil-free? Sure! As long as you plan to replace it sooner than later.

Asked by dw October 20, 2016

(What's this)
At first glance, I was a little put off by this nailer. I noticed right away that a small amount of rust had built up on the air inlet port and thought that was a little odd, considering this is new-in-box. I’ve used pneumatic nailers and staplers for a short while now and have had great success with a few different models. But out of the box, I had never seen any with rust on them, so it must have been an anomaly. Thinking that there was rust on the outside, I considered that it might not have been lubricated before it shipped. It did ship with small bottle of lube oil, so I used that to drop a few drops in the inlet per the instructions. The instructions did not indicate how much to dispense into the nailer, so I best guessed off of over nailers that I have used. It was at that point I found the instructions were a little odd. I found a few places where things didn’t quite add up, the English was a little off or a few seconds of spell checking could have helped. My favorite was the captioning of the depth adjustment wheel. It seems that the manual may have gone through a few changes before it went to print and they missed the fact that their figure letters were mismatched! It caused a bit of confusion, but I was able to figure it out. I used this nailer with some 2” 16 gauge nails. 16 gauge goes in one side, 18 gauge on the other. The loading tray is just shy of 2” long, so longer nails will hang of the tray which seems a little funny to me. However, I had no misfires or jams while sending a 100 nails through it. The load action is smooth and easy which is nice. A small window in the load tray shows the nails in the tray, and is very close to the top so you know when you’re very low. Other nailers I have used have had the window about halfway down the tray, which just don’t make a whole lot of sense. The nailer has a hard rubber tip, so you don’t have to worry about dinging or stratching the wood you’re working on. Overall, a good nailer. I like that it can use multiple sizes of nails, so I don't have to worry about having multiple nailers. The rust makes me worry a little about the interior components. Additionally, I feel like it could be a little bit lighter.

I've never seen a multi size nail gun before. I was a little skeptical of a 3-in-1 from a company I had never heard of for less than $100 no less. Glad I didn't listen to myself. This thing is excellent for diy-er's. Load 16ga on 1 side or 18ga on the other or 18ga staples in the center. The exhaust port is adjustable which is a plus. It can be set to single or multiple shot, which is also a big plus. You can also set your drive depth, another plus! Seems well built so far. I've put a few 100 of each fastener through it so far with no issues. Saved me a few $100 as well from not having to purchase or even decide between a 16 or 18 gauge. I definitely recommend this nail gun.

Bought It & What A Waste of Time.
I was so excited to of bought this 3 in 1 tool. Ordered in online, hooked it up to the compressor, shot a testing row of about 12 nails then the gun stopped working. Air started coming out of the trigger which means the gun went bad within test shooting 12 nails. NuMax please use better interior parts. This item is pure garbage,

The fact that this nailer also fires crown staples causes a problem on finish work with 16 or 18 gauge nails. Next to the driven nail head, you will see an adjacent dent about 2-1/2 times the size of the nail head. That is because the there is only 1 driver for all 3 types of fasteners and it is the width of the staple head. Wood putty does fill the nail head but it does not stick to the the dent. You will see a putty hole with a dent next to it. I wanted to use this on oak stairs treads and trim but it caused too much damage. I assume all nailers that are 3-in-1 do the same thing and it is not particularly this NuMax it's the technology. If you don't care about the dent when driving nails, this would be a good choice. .

Purchased this nailer to install base molding and door trim. The shipping box this came in looked like someone sat on it and the outer sides were dirty as if it was dragged on the floor several times. When I opened the shipping box, the product package box had pierced holes in three spots on the locations of the product air hose connection point, the gun point and the air exhaust end but the product itself looked fine upon initial inspection. After test firing a dozen 18 gauge nails, I noticed the non-mark tip on one side along the tip edge had tore off. I later found the piece in the product package box. The first two dozen or so nails went into the molding, drywall and stud pretty well about 2/3 of the time, the remaining times, the nailer misfired, left marks that needed to be filled, or exposed nail heads that needed to be set with a nail setter. After that, the nailer misfired more frequently, left more nail heads exposed, and left more marks. I tried the depth adjust to no avail as well as the pressure setting from my air compressor from the lowest setting to max pressure setting for the nailer. Overall about 70% of the time the nailer misfired, left deep, wide marks on the wood or left the nail head exposed anywhere from 1/32" to almost 2" whether it was 16ga or 18 ga nails. I was using Dewalt brand nails. Did not try staples. The nailer has really useful features like the quick jam release and depth adjustment that was really useful and overall seemed to have decent materials. Maybe the tool got damaged at the warehouse or during shipping due to rough handling or maybe it was a defective unit. In any case, it didn't live up to expectations. Too many misfires, nail setting, filling holes and sanding for the convenience and savings of a 3 in 1 tool. Ended up getting an 18ga brad nailer and a 15 ga finish nailer and have been much more satisfied with the results. Returned at my local HD store with no issues. Had the tool about 45 days and used it twice before returning.
