The Porter-Cable palm nailer is well thought out, for use by the professional, like all of Porter-Cable’s tools. This one comes with four different nose tips, including a no mar finish tip for use with finish nails and a standard magnetic tip. It also has a steel hammer kit for use with moldings, dowels, and automotive body work. This nailer will drive nails up to 6-1/2 inches long. It has a depth of drive adjustment, so you can select to drive your nails flush or a little proud. It’s also the lightest around at 2.5 pounds. Comes with a glove with padded Velcro strap.
Bostitch’s kit comes with three nose tips; magnetic, standard and large bore, all packed together in a convenient carry case. All nose pieces are magnetic and hardened steel for extreme durability. They also packed a set of spare O-rings in the kit, along with the lubricant and hex wrench needed to replace the O-rings. The glove for this one isn’t made of leather, but rather something that looks like black nomex. It covers the ergonomic back of the nailer, making it comfortable to hold.
Senco actually makes a couple of different models of palm nailers, with this being their standard sized one. The back of the nailer is soft rubber to avoid vibration, with the glove covering the sides for secure grip. This one comes in at the same 2.5 pound weight as the Porter-Cable unit. It will drive nails from 5d through 70d, giving it the biggest range of any palm nailer I’ve seen. It seems that it only comes with one nosepiece, but that nosepiece is magnetic for easy nail handling.
Ridgid’s palm nailer is more correctly characterized as a mini palm nailer. This one is designed to handle nails a maximum of 3-1/2 inches long. It has no glove, but rather a rubber padded back, with an adjustable hand strap. The single nose is magnetized for ease of nail locating. It also has a self-cleaning air filter in the handle, to keep debris out of the tool and extend tool life.
This is another mini palm nailer, intended for use with nails that are up to 3-1/2 inches long (16d). It is incredibly lightweight at under two pounds. Even so, it has a magnetic nosepiece for holding the nail. No glove or strap is provided, but it does have a thick rubber cap over the back of the tool to absorb vibration and make it comfortable to work with. The small body design is easy to hold on to.
