What are the differences between Bosch GBH18V-40CN and Bosch GBH18V-36CK24?

The Bosch GBH18V-40CN and Bosch GBH18V-36CK24 are two top-tier cordless rotary hammers that bring serious power to the table, but here’s a breakdown of how they differ to help you decide which one suits your needs.

1. Power & Performance:

• The GBH18V-40CN hits harder, offering 6.7 ft-lbs of impact energy, which makes it ideal for the toughest jobs like breaking up large sections of concrete. This model is better suited for more demanding applications where maximum power is essential.
• The GBH18V-36CK24 isn't far behind with 5.2 ft-lbs of impact energy. It's still highly capable for concrete drilling and chiseling, making it versatile for most job sites, though it’s slightly less powerful than the GBH18V-40CN.

2. Weight & Usability:

• The GBH18V-36CK24 is lighter, weighing around 13.4 lbs with the battery, making it easier to handle for longer jobs. This could be a better choice if portability and reducing fatigue are important to you.
• The GBH18V-40CN is heavier, at 18.4 lbs, which provides more stability for heavy-duty tasks but may be tiring for extended use.

3. Battery Power:

• The GBH18V-40CN comes equipped with two 12 Ah batteries, giving it extended runtime, which is crucial for large projects where recharging frequently would slow down your workflow.
• The GBH18V-36CK24 includes 8 Ah batteries, offering solid performance but with a shorter runtime compared to the 12 Ah setup on the 40CN.

4. Special Features:

Both models feature BITURBO Brushless motors, advanced KickBack Control, and anti-vibration handles for better safety and comfort. They also include a user interface for monitoring performance, and both are compatible with Bosch's AMPShare system, allowing you to use the same batteries across multiple Bosch tools.

In conclusion, go for the GBH18V-40CN if you need maximum power and runtime for heavy-duty work. The GBH18V-36CK24 is a great alternative if you prefer something lighter without sacrificing much in terms of performance.
