The Ryobi PSBIW25B is an 18V ONE+ HP brushless compact 1/2 in. impact wrench that is 35% lighter and 26% more compact than the full-size PBLIW01B, making it the better choice when tool access or all-day carry weight is the primary concern. It delivers 275 ft-lbs of breakaway torque through four modes — three speed settings plus an auto-stop mode — which covers passenger vehicle lug nuts, general automotive service, and common construction fasteners without the bulk of a high-torque gun. The compact brushless motor keeps the weight at just 3.8 lbs, significantly reducing fatigue during overhead or extended use. This is a bare-tool listing — no battery or charger is included.
Does the PSBIW25B come with a battery?
No. The PSBIW25B is a bare tool — only the impact wrench is included, with no battery or charger. You will need a compatible Ryobi 18V ONE+ battery and charger. The PSBIW25K1 kit includes a 2.0 Ah HIGH PERFORMANCE battery and charger if you need a complete setup.
How does the PSBIW25B compare to the full-size PBLIW01B?
The PSBIW25B is the compact model: it is 35% lighter (3.8 lbs vs. 7.0 lbs) and 26% more compact, but produces 275 ft-lbs of breakaway torque versus the PBLIW01B's 1,170 ft-lbs. The compact model is well suited for standard automotive lug nuts and general service work; the full-size model is intended for seized fasteners, heavy equipment, and applications requiring sustained high torque.
What is the maximum torque on the PSBIW25B?
The PSBIW25B produces 275 ft-lbs of breakaway torque (3,300 in-lbs). This is adequate for most passenger vehicle lug nuts, whose factory torque specs typically fall between 80 and 120 ft-lbs, with breakaway torque to remove them even if they were overtightened.
What are the 4 modes on the PSBIW25B?
The four modes are low speed, medium speed, high speed, and auto-stop. The three speed modes let you match power to the fastener size and material, while auto-stop mode cuts power when the tool senses the fastener has reached the target resistance — useful for preventing overtightening on sensitive assemblies.
What batteries are compatible with the PSBIW25B?
All Ryobi 18V ONE+ batteries are compatible, from compact 1.5 Ah packs up to 6.0 Ah HIGH PERFORMANCE cells. Because the PSBIW25B is a compact tool designed around portability, a 2.0 Ah or 4.0 Ah battery balances weight and runtime well without making the tool front-heavy.
