Features and working of a framing nailer

Framing nailers work by shooting nails into the target material at high velocities. To generate this propelling force, the tool is powered either through compressed air or through Rechargeable batteries. In the former case, the nailer is linked to an air tank in which pressurized air is stored. When the tool’s trigger is pressed, this air is directed into the nozzle of the tool pushing the nail out at high speeds. In the latter case, the rechargeable battery is used to create an electromagnetic field around a coil called a solenoid between which a magnetic piston is placed. Due to similar magnetic poles repelling each other, this piston is propelled forward, shooting the nail out of the nozzle. Cordless nailers do not have a power cord and since they do not require to be connected to a power cord to function, and thus are completely portable.

Fasteners such as nails that are driven by framing nailers have a higher removal resistance than the nails manually hammered into the material. The nailers that work on compressed air are called pneumatic nailers. These nailers generate a pressure of around 70 to 150 pounds per Square inch to output a torque of approximately more than 2000 inch pounds. A magnesium housing lightens the tool, with the average weight of the nailer being approximately 7 to 9 pounds.

Most nailers are compatible with fastener sizes ranging from around 2 to 4 inches in length and around 0.113 to 0.162 inches in diameter. The Magazine capacity is around 150 to 200 nails. The magazine is most commonly made of aluminum. Battery operated nailers can shoot out around 4000 nails with a single charge, at the maximum cyclic rate of around 3 to 4 nails per second. The depth-of-drive of the tool can be adjusted by the user depending on the application, the density of the target material, and the length of the nail. This enables flush nailing into the surface.

What to look for in a nailer

Considering the high velocity at which the nails exit the nozzle, the safety factor of the framing nailer cannot be ignored. To prevent the tool from firing nails into the air, the device has an intrinsic safety valve, which prevents the tool from firing unless the nozzle is pressing against a hard surface. During use, exhaust may sometimes get ejected from the tool. Some nailers incorporate a 360 degree exhaust deflector that aims the discharge away from the user.

The handle of the nailer is ergonomically contoured with a soft padding to enhance comfort for the user. The balance and weight distribution of the tool is also judiciously designed offering better maneuverability in relatively inaccessible locations. The trigger and the controls should be conveniently located to offer easy usage and one-handed operation. An oil-free engine needs no lubrication or maintenance and also enables cleaner functioning. Some nailers have an auxiliary handle for more stability and control, providing better accuracy. A built-in air filter prevents dust and dirt from entering the tools and clogging or damaging the internal components. A detachable no-mar tip ensures that the work surface is not dented or scarred.

Some reputed manufacturers of framing nailers include Bostitch, Campbell Hausfeld, Dewalt, Makita, Milwaukee, Porter Cable, and Senco.
