In 1984, Bosch launched the world's first cordless hammer drill, revolutionizing the tool industry. In 2021, Bosch made another breakthrough by introducing cordless drills and cordless hammer drills that match the power of corded tools: the GSR 18V-150 C and GSB 18V-150 C. Behind the power of these two models lies the BiTURBO brushless motor, which was adopted in several motorized tools before being incorporated into cordless drills.

In this article, we won't be focusing purely Bosch cordless drills, on the GSR and GSB 18V-150 C models, but we'll take a slight detour to delve deeper into the technology behind them. If you are interested in either of these models, you can check out our review below.
BiTURBO combines two technologies: the BiTURBO brushless motor and the ProCORE battery. Bosch developed this new brushless motor to unlock the full potential of the battery developed earlier. The performance of tools powered by BiTURBO technology matches that of corded tools delivering up to 1,800W of electrical power.
BiTURBO Brushless Motor
The Neodymium magnets in the BiTURBO brushless motor possess the highest magnetic strength available today. They can be made compact while retaining immense magnetic pull. As a result, this new brushless motor can deliver high power and achieve high torque accordingly. This is why BiTURBO tools perform on par with 1800W corded tools while maintaining the compactness of cordless tools. However, you must use BiTURBO tools exclusively with a ProCORE 18V 8.0Ah or 12Ah battery to achieve maximum performance.
Not only that, BiTURBO tools also come with overheat protection. Bosch designed the motor fan to generate airflow of up to 1000L per minute to prevent potential heat damage and simultaneously extend battery life.
ProCORE Battery
As already known, BiTURBO tools can perform at full efficiency only when used with 18V 8.0Ah or 12Ah ProCORE batteries. The ProCORE battery features 21,000 battery cells and comes with new battery management technology from Bosch that delivers up to 87% more power than conventional batteries, along with COOLPACK 2.0 technology to aid heat dissipation, enabling the battery to last up to 135% longer than conventional batteries.
“Just a single ProCORE battery can deliver performance equivalent to two standard batteries.”
Of course, ProCORE batteries are priced higher than standard batteries, but they are a worthwhile investment considering the performance you get.
COOLPACK 2.0 Technology
High heat adversely affects battery life. COOLPACK 2.0 technology was developed to help dissipate heat in ProCORE batteries. It features copper sheets that Bosch calls ‘Cell Connectors’, which act as conductors to channel heat away from the cells, engineered with reduced internal thermal resistance via laser welding, as well as a polyethylene battery cell casing that also serves as a heat conductor.
Using BiTURBO Tools and ProCORE Batteries
All Bosch 18V cordless tools since 2008 are compatible with ProCORE batteries. Conversely, BiTURBO tools can also be used with older battery models. However, we recommend using BiTURBO tools with ProCORE batteries to unleash the tools' true performance.
The BiTURBO lineup includes circular saws, miter saws, grinders, rotary hammers, and most recently, cordless drills. These tools are designed to be compact, lightweight, and comfortable to hold. Combined with ProCORE battery power, they allow you to handle a wide variety of tasks continuously for extended periods.
