depends on Ur application n max size of drill bit n penetration depth.

I just bought a chin up bar ytd and realize that my drill isn't powerful enough.

The bolt is 7cm long 1cm diameter.

This type of hope need to use how many watt hammer drill?

13mm max i guess

13mm max i guess

then an impact drill in the order of 600W ~ 1000W should be sufficient.

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.

Anyone heard of ATA Rotary Hammer Drill.... S$104

This Is a brand new ATA Rotary Hammer Drill SDS plus Chuck Head

Able to Drill up to 26mm diameter hole in concrete. Proven by contractors!

Is this a good buy? compare to

1. MAKTEC MT811 13MM Hammer Drill S$83

2. Bosch Hammer Drill GSB 16 RE Professional $125

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.

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.
