Advanced Features Of NuMax SFR2190 That Make It Standout

Quality Build

You are going to deal with a necessary but little challenging tool where durability and lightness is an essential trait. NuMax address that brilliantly and use magnesium to build their nailer SFR2190. Magnesium is known as the metal of the future, because it is 30% lighter than aluminum, 60% lighter than titanium, and 75% lighter than steel. Nonetheless, it is stronger than those three metals per unit volume.

Therefore, NuMax SFR2190 will allow you to work all day without any pain as well as it will not easily fragment even accidentally slide from your hand from high and drop on the hard floor.

Is Numax SFR2190 Framing Nailer Good For You

Ease-Of-Use And Comfortable Grip

You already noticed that the NuMax framing nailer is constructed with durable and lightweight metal. However, it weighs 8.6 pounds which may feel significant if you use a couple of hours together without a break and your arm is not strong enough. On the other hand, if NuMax makes it much lighter then there is a chance to transmit the recoil force onto your forearm. So, there observed a proper weight balance ratio in this tool. 

Also, it comes with an ergonomic design and a Non-Slip handle that is easy to grip and works both horizontally and vertically. It will also provide anti-vibration comfort during drive nails.

Ease-Of-Use And Comfortable Grip

The Dual Actuation

The dual trigger option of the NuMax nail gun enables you to switch between sequential and bump fire so you can do both single actuation and or continuous nail shooting as per job site requirements. It does not have a selector knob like other contemporary nailers. But for safety, it is better to stick with the sequential actuation mode.

It is especially good for those who are first-time shooters or average pros. On the other hand, if you’re a professional framer, then switching to bump mode isn’t a large deal.

Regarding body stature, you will not find any difference in the NuMax SFR2190 from the other high-end brands, and could be nailing where others can access it. However, it is a bit challenging to do nailing in a tight space smaller than 16″ OC. Otherwise, I’m sure it will give you uninterrupted service which helps you to complete any small or big project smoothly.

Versatile And Powerful

NuMax SFR2190 is an innovative and powerful framing nailer that can shoot any generic nailer 10-12 GA from 2 to 3 and 12 inches. It can not only frame or nail 24s studs but also roof and wall sheathing, siding installation, wood box assembly, fencing, and so on.

Depth Adjustment Mechanism

During work, you may have to fasten different hardened woods and need to adjust the depth of drive accordingly. Keep this in mind Numax framing nailer offers a depth adjustment system. By turning the depth wheel left or right you can regulate depth-of-drive without problems.

360° Adjustable Air Exhaust

It is an operational hazard that you drive a nail and exhausted air comes directly to your face. You will never experience this problem with Numax SFR2190 as it has a 360° adjustable air exhaust. Moreover, you can use it to clear debris from your workplace.

No-Mar Tip

It would not look good if your nailer left some mark on your work surface. No-Mar Tip features of Numax SFR2190 eliminate that tension. Now you can drive a nail without any dents or dings and get a professional finish.

No-Slip Teeth

For safety especially when you do toe-nailing no-slip teeth are essential. In such a case, if you take off the no-mar tip, the no-slip teeth will be exposed easily on your Numax SFR2190.

Anti-Dry Fire

Some framers do not like this feature as it does not fire the last three nails due to the anti-dry fire mechanism. However, it is not acceptable to shoot when there are no nails in the gun as it may cause damage to internal parts and decrease lifespan. Once you load a fresh strip of the nail in the magazine, it will back to its original mode, and you can go forward.

Anti-Dust Cap

Air filters or anti-dust caps keep clean the internal parts of your nailer specifically when left at the store or not at work.

Limitations Of Numax Nail Gun

It has to change the trigger instead of just pressing a switch to turn bump mode to contact actuation.

Yes! It is true that it doesn’t have a bump-fire selector switch like other branded products. Instead, you have to change the entire trigger to shift from one mode to another, which is a hassle.

If you are a pro framer, you may not require sequential fire mode during driving nails into 2×4 studs. But, while you will fasten plywood sheathing or any such, you may need to quickly change the trigger. Which is not possible with this tool.

However, It is not a deal-breaker for DIYers in any way. Moreover, it is safe and precise to use single firing mode.

The Jam Removing System Is Not Tool Free

Yes! It is true that you must manually clear the jam on your Numax nailer, whereas most brands offer tool-free jam removal. However, the reality is that you will face very few or zero jam problems with the Numax nail gun. Fortunately, if you encounter any such situation, it is not a big deal to unjam your device.

Depth Adjustment System Is Not Easy to Turn

If you lift the nose piece slightly upward then you can quickly turn the depth wheel. Moreover, using oil at regular intervals will give excellent support too.

From the above comparison, we see that all the framing nailers are primarily good to do framing jobs and can also be used for other woodworking jobs like flooring, fencing, siding, roofing, or sheathing. Then selecting the right tool is going to be a difficult task. To find the solution, we have to look at the degree angle of the magazine.

The magazine of the Numax SFR2190 is designed to drive 21 degree round head nails, whereas SFR2890 and SFR3490 are designed to drive 28 and 34 degree nails respectively. And the last one is a finish nailer which is different from the first three models and mostly suitable for finish or trim works.

21 degree framing nailers are good for heavy-duty work like building or remodeling homes and framing. Whether you can also use 28 degree nailer to do those, but 28 degree framing nailers usually drive clipped head nails which will not give you 100% gripping power like 21 degree framing nails. So, most of the building code doesn’t allow 28 degrees for heavy-duty tasks.

On the other hand, when you need to drive nails at tight corners, 34 degree framing nailer will give you more leverage than others. Therefore, you have to choose the framing nailer degree based on the project you’re going to handle.

Frequently Asked Questions For Numax SFR2190 Framing Nailer

What is better a 21 degree or 30 degree framing nailer?

When it comes to selecting a framing nailer, choosing between a 21 degree or 30 degree option can be a difficult decision. Both nailers have their own unique advantages and disadvantages. A 21 degree framing nailer typically provides a greater range of fastener options and can handle a wider variety of projects.

On the other hand, a 30 degree framing nailer is known for its ability to access tight spaces and its ability to drive nails at a more consistent angle. Ultimately, the decision between the two will depend on the specific needs of the user and the nature of their projects.

Does it come with any compressor? If not, what will be the recommended size?

Nope. The package of the Numax framing nailer does not include any air compressor. So, you have to buy it separately, if you have no one at your store. The recommended air compressor specification is – volume: minimum 2.5 CFM @ 90 psi, pressure: 70 – 115 psi, tank capacity: at least 3 gallons. You will get more information about buying an air compressor on our page air compressor for nail guns.

What type of collation is suitable for this nail gun?

Numax nail gun allows any generic branded plastic collated nails from 20 to 22-degree ranges and 2 to 3½ inches in size. Therefore, you can choose any plastic collated nails from your nearby hardware stores or from online.

Round or clipped head, which one is suitable for firing with this gun?

It allows round-headed nails to shoot. And you will be happy to know that building code in most states permits round head nails because of their extra holding power over clipped head nails.

Is it challenging to clear a jam?

If you apply the oil twice a day, the chances of jamming occurring will significantly reduce. It’s not a tool-free jam release system, though; making it unjammed isn’t a major problem. You just need an Allen key.

What gauge nails are suitable to drive with it?

Numax SFr2190 framing nailers can drive 10 – 12 GA or 0.113–0.31-inch-diameter nails comfortably. 10 -gauge nails are usually bulkier in diameter and a perfect match for heavy-duty tasks like framing, decking, or fencing.
