The new two-speed cordless drill/drivers from Bosch offer 30% more power and 15% more running time than their predecessors according to the company.
This means that the PSR 14.4 LI-2 and PSR 18 LI-2 lithium-ion drill/drivers will drive up to 300 more standard-sized screws than previous models.

This is made possible by the new PowerPack 1.5AH lithium-ion batteries.

Rrps are £99.99 and £119.99 respectively.
