Hahaha... this thread rocks!!!! Before I read this thread, I don't know there is a different between normal drilling machine(I forgot it's name) and rotary hammer. I just assume all are 'normal drilling machine'.

But because of this thread, I now know about rotary hammer. I just bought one cheap rotary hammer at Giant call Starke Plus 710w at RM199. If wait another 3 more days, I can get the same machine at RM159.

I just buy the cheap one because I just need to make one hole only to pull network cable through wall. But I realize after using it for the first time, I felt in love with it. This machine super rock!!! Never regret buying it. But I don't know what to do with it after this. Maybe, I will using it to hang a picture or other stuff that normally I just use my 'normal drilling machine'.

I also read about the envelope thing to collect dust. Usually, I just use small box bigger than match boxes to collect dust while sticking it to the wall using masking tape. This box have been with me for more than 8 years and still collecting dust for me.

By the way, thanks Bahathir for the useful info and sharing knowledge.

I bought the machine on 20th March. The offer start on 23rd March until 11th April.

So, if I wait another 3 days, I will save RM40. But what to do. I can't read the future.

Please define heavy user. I want to know... really.

Actually, my regular DIY store manager toled me that the green Bosch is highly sought after even it is second hand. This is because the green one is more tough and durable than the blue one.

I don't deny this because I have the green and the blue Bosch. I know which one more tougher.

By the way, with the metal price is increasing but the price of today machine is still the same or even cheaper than 10 years ago. So you can expect some cost cutting measure somewhere.
