I have been using this specific tool for a year now with an 8Ah battery that lasts me about half an hour of digging in concrete or brick. With the Bosch gal 18-160 charger, it charges in about half an hour! You can't tell the difference from electricity because of its power! Additionally, the 70% option is very useful for weak mortar, bricks!!! I highly recommend it!

Very good, worth it. Also, the function with the soft start is quite useful on tiles and rough surfaces. I have a pro core 8 ah battery, it's killer. I used to work with a similar one from Dewalt, this one from Bosch is better and more powerful.

Very good in drilling and shaping, I have it in my possession with the PROCORE 18V 7.0 AH battery, I highly recommend it without hesitation!
