Overview

Running on an 18 volt RYOBI battery instead of a compressor line, the P321K nailer weighs 6.5 pounds and fits RYOBI's cordless tool platform.

Because it draws power from a battery rather than an air hose, there is no compressor or hose to drag around a job site. The K in the model typically denotes a kit designation on RYOBI tools, though this listing does not spell out exactly what is included.

  • 18 volt battery powered
  • 6.5 pound weight
  • No compressor needed
  • RYOBI cordless platform

Who it's for

DIYers and trim carpenters who want cordless convenience without hauling a compressor and hose. Not for buyers who need pneumatic-level driving power for heavy framing fasteners.

Pros and cons

Pros
  • Cordless, no compressor or hose
  • 18 volt RYOBI battery platform
  • Light at 6.5 pounds
Cons
  • Battery and charger inclusion not specified
  • Less driving power than pneumatic nailers

Performance notes

18 volt battery nailers generally trade some driving force for cordless freedom compared to pneumatic models. At 6.5 pounds the P321K is light enough for extended one-handed or overhead use without the fatigue a heavier tool would bring.
