Road to the Best Nail Gun for Trim
Trim work needs extra care, and it requires unique nail guns for the perfect finish. If you want the best nail gun for this job, you have to dig into the basics. This section will have you covered.
Nail Gauge Size
Whether it is a framing nailer, finishing nailer, or a brad nailer, the size of the nail gauge is different for each one of them. The finish nailers typically use 15 to 16 gauge nails the most. The 15 gauge nails are thicker and longer and best suited for more dense and heavier woods.
On the other hand, the 16 gauge nails are thin and small and perfect for light woods and trims. The 18 gauge nails are called brad nails. They are used in situations like delicate trim tasks where you need a smooth finish.
Nail Gun Power Source
The power source of a nail gun determines how it works and the type of work it can handle. A pneumatic gun uses pressurized air from a compressor and drives nails. They are powerful yet lightweight. And hence they are most used in trims and related finishing projects. However, mobility is an issue with this type of nailer owing to the air hose and compressor.
Another type of nail gun is the cordless ones. They are battery-powered and do not require any hose or compressor. As a result, they cost much less and offer excellent mobility. However, they do not have as much driving power as the pneumatic ones.
Trigger Type
Nailers utilize several types of triggers. One of them is called contact firing or bump firing. In this case, you have to press the gun’ against the work surface and pull the trigger. It will fire multiple nails in a single press.
However, you will need to move your nailer fast for contact firing. Otherwise, it may double fire and create a hazardous situation. Therefore, it is not suitable for trims.
Another type is sequential firing which is much safer. This is because you have to press the safety tip against the work surface each time you pull the trigger. Therefore, it is perfect for handling delicate trim tasks.
Nailer Angle
Nailer angle means the angle of the nail magazine. Nail magazines can be angled at 15 degrees, 20 degrees, or 30 degrees. Many models have angles in between as well.
A higher angle offers more space to work with. It is better to find an angled nailer for trims. However, you have to find the supported nails to use a specific angled nail magazine, which is often complicated.
Size and Weight
Nailers are essentially handheld tools as trims need more care than conventional projects. So you would expect the nailers to be more lightweight and compact. Generally, nailers used for trim weigh around 2 pounds to 4 pounds.
Also, you can use a lightweight nailer for an extended period without straining your hands. Therefore, it is recommended that you check the size and weight of the nailer before buying.
Features
Regardless of the type of your nailer, it must have the option to adjust the depth at which you will be driving the nails. Besides the depth adjustment wheel, the nail gun for trim must also include other necessary features such as jam clearing latch, dry-fire lockout, rotatable exhaust, etc.
