The 4.0 Ah HP pack is compatible with the entire 300+ tool 18V ONE+ ecosystem.
What does the P322K kit include?
The P322K includes the P322 brushless AirStrike 18-gauge brad nailer, one 18V 4.0 Ah HIGH PERFORMANCE battery, an 18V charger, and two non-marring pads. Everything needed to start nailing is in the box.
How many nails can I drive per charge?
With the included 4.0 Ah HP battery, the P322K drives approximately 2,250 nails per charge — notably more than the brushed P321K1 kit, thanks to the brushless motor's higher efficiency.
Is the P322K worth the upgrade over the P321K1?
For frequent or professional use, yes. The brushless motor is more efficient and consistent in harder materials, and dry-fire lockout prevents tool damage and surface marring. For occasional light trim work, the P321K1 is a capable lower-cost option.
Can I use the included 4.0 Ah HP battery in my other Ryobi tools?
Yes. The 4.0 Ah HIGH PERFORMANCE battery works with all 18V ONE+ tools, giving it value beyond just the brad nailer.
What gauge nails does the P322K accept?
The P322K accepts 18-gauge brad nails from 5/8 in. to 2-1/8 in. in length. 18-gauge brads are the standard choice for finish trim, crown molding, chair rail, and light cabinetry where a small, inconspicuous nail hole is preferred.
