Bosch Cordless Drill PS31 (2009)

The Bosch PS31 is a compact and lightweight 12V Max cordless drill/driver designed for a range of tasks, particularly in tight spaces or overhead. It was introduced in 2009 as an upgrade to the previous PS30 model, offering improved performance and a smaller size. The PS31 was discontinued in 2014 and replaced by the PS32, which included updates in motor technology and efficiency.

Bosch markets its cordless drills primarily to trade professionals and DIY users. Their tools are sold worldwide through a broad network of retail and service channels, without regional restrictions.

This drill is part of Bosch’s 12V Max system, which uses interchangeable 12-volt lithium-ion batteries compatible with various tools such as drivers, saws, and lights. The PS31 uses a brushed motor and is intended for light to medium-duty work.
