Actually seafreight from China is about 2-3 weeks max.





This rotary hammer and its accessories plus shipping is about RM 270.. Just tested, ok la...

wht r u gona use it for?

im goin to buy the hole saw on the left. not sure if it works well....

Yeah, to open hole on the wall for the aircond piping.

I am still waiting for the diamond core drill to come as I just had it sent out from the port. I will be using the diamond core drill for 100mm and 180mm hole opening on the wall...

180mm ?
manyak besar itu lobang....

Ya, for hood ducting. But I will not be the one using coz I do not think I can hold that drill... And the torque is going to be enormous...

how much is the 180mm diamond core ?

Complete set (drill + water pump) with 32, 63, 83, 102, 120, 168, 180 diamond core drill bit plus shipping about RM 900.

From the lelong here: There is a similar core drill by Skil
http://www.lelong.com.my/skil-2800w-200mm-...4-08-Sale-P.htm but this one is better as it is 2800w + 200mm diameter. Mine only 2200w max 180mm, but with lots of bits included

For that 180mm drill bit alone, about RM 180.

You don't need Dimond Core drill for that. You can drill that Dia180mm hole with the Hammer Drill you already bought, just mark out the 180mm circle, then mark out a concentric Dia168mm (180-12) circle and drill a series of dia 6mm holes on that 168mm circle so each hole has about 3mm gap, then use 12mm drill bit to enlarge each hole. then a little bit of hackingwitht he chisel bit to smooth out the 180mm hole shape and job is done.

The hole doesnt need to be super perfect since inside and outside should have a cover plate and a duct passing through the hole, right.

That's how about 90% of contractor would do it.

cheers

mebe this way is faster...

Wouldnt it be tiring to drill so many holes? Btw, diamond core drill has a water outlet so that water will go thru to prevent the drill waste from building up to smoke...

I didn't say it was the best way to do it, i said that's how about 90% of contractors do it.

It might take 1hr to do by hammer drill vs 30 mins by core drill, but you don't need to spend rm1k for core drill.

Also core drill not really easy to use on wall, its really best suited for boring through concrete floor.

Btw, hammer drill can really drill thru with a 160mm hole saw?

No it cant , but I never said that.

There is a way to drill any size hole (160mm 180mm 200mm 350mm even) with standard Hammer Drill as given in my explanation of the method above, read that explanation and you should understand. Its not using hole saw or core drill bit, its using normal concrete drill bits and just dilling lots of holes that join together, a bit like perforations on paper.

Cheers

Oopss.. Got it... Want to ask another noob question. I think it is practical to put some grease at the thread of the hole saw? I tried using it today, and when I wanted to remove it after testing... I think it got stuck due to the torque...

can drill wall tiles?

wall tiles different bit

I think it maybe a bit too strong for wall tiles?

hmmm...any suggestion on driller? i need to drill bathroom and kitchen tiles wall to hang accessories usually found in both these place..
