Misc100 2 Report post Posted March 14, 2011 depends on Ur application n max size of drill bit n penetration depth. 13mm max i guess Share this post Link to post Share on other sites
neubie 2 Report post Posted March 14, 2011 13mm max i guess then an impact drill in the order of 600W ~ 1000W should be sufficient. Share this post Link to post Share on other sites
lorddraco 1 Report post Posted April 8, 2011 if you are drilling reinforced wall. dont get black and decker. I try using a B&W 700W, supposely more powerful to drill holes in my store-room. Takes ages .. never go deeper than 2cm. I use an nearly 20years old Bosch 400W ... it goes easily to depth I want. For really serious and heavy work. Bosch is much better in quality and power. Seems to me the B&W 700W is fake. Share this post Link to post Share on other sites

Seems to me the B&W 700W is fake.Thats weird ... i just used a 710W B&D drill and used the right masonry drill bit. It took me about 20-30 seconds to drill a hole of 45mm in hard concrete walls.

RimBlock 0 Report post Posted May 19, 2011 I bought a Bosch drill around 3 months ago. It was something like this one which is mid to upper level of their range.As a drill it goes maybe 1" into the concrete. As a rotary hammer drill it goes through concrete like butter.I would go for Bosch or Makita given a choice.RB Share this post Link to post Share on other sites
