12x12, almost 6 inch thick. Sudah beli, mesti pakai. The day before buat 5" dia exhaust for dryer.

Chisel sudah tumpul, then cannot use grinder to cut because the whole house dusty nanti. Still cannot find proper dust attachment for grinder.

How long it takes to complete the hole?

cleaning aside, 30+ min. Could have been faster, but too many premise, hammer pun tak tahu mana. the only one i have is a small cross peen pin hammer...

cleaning kira..almost 2 hours.

I would normally use grinder to cut a groove. Than rotary hammer to have a clean hole cut.

So no need to cement repair the crack edge. Which is very ugly after repair. (Not my expect)

I saw many grinder dust extractors in Shopee that would work for Bosch and others. I think around RM60~70. Some with different size attachment for rare size as well.

Yes, without dust extractor it become very cloudy like thunderstorm is coming

Many just put bezel to cover it and look nice

mmng i want to do that, but that is my TV room...its going to be super messy. However, the ventilation fan covers all the crak anyways, so no extra work required, i considered that masa buat kerja too.


bosch dust extractor x mahal pun, rm150 ish ish, but i cant fit the slim grip bosch grinder i have.

Yeah the cleaning is a pain.. lol

Grinder dust goes everywhere. Had to grind off wall like /_\ so my cabinet drawer can open without scraping the wall, that created a desert storm.

For this hole i would draw the outline of the hole with marker pen
Then pick the least used drill bit to be condemned for this.. maybe 8 or 10 mm (hardly used)
and drill a series of holes near to each other within the hole lines like ..........
So its easy to chip off using the rotary hammer and makes a very clean line

Desert storm more like

Hi guys, I've been reading past thread and started to narrow down from cordless GSB 120, to wired GSB 10RE, GBM 350 and now GSB 500RE because it encompass masonry, wood, steel and concrete... but seems like my journey is not over yet. Seems like all the model I listed are at most an impact drill.

Now I wonder if I should look for rotary hammer because 500RE is not that great for concrete it seems. Perhaps as a beginner looking to just drill holes for the blinds, screws and cloth hangers, 500RE may just be enough. I keep reading that I should opt for rotary hammer, but are they over kill for the purpose I just mentioned since they can be bulky and heavy?

If rotary hammer is an overkill, should I opt for GSB 550RE, 13RE, 16RE or 1300?

Need sifu recommendation here. Thanks in advance for your time

What kind of wall do you have?
Brick wall (clay or sand brick) = any >500W hammer drill will do (bosch GSB10RE). This will NOT work well for concrete wall.
Concrete wall (RC wall/AAC brick) = investment in rotary hammer is needed (bosch GBH2-24, Makita HR2470 or any other rotary hammer using SDS+ drill bit) else you will struggle 10 mins per wall plug hole - rotary hammer can do in 10 seconds

The above are corded (wired) models.

If you wanna do cordless u need to invest in battery and charger.
Nowadays cordless tools are cheap (comparable with wired models prices) if don't count the batt and charger price.

Cordless drill+driver for brick wall onlyGSB180-Li, will work great for drilling wall plug and as cordless screwdriver.
Around 180-220 for tool only, some c/w carrying case some without - when you shop on pee pee

Cordless rotary hammer for concrete wall GBH180-Li around 350 for tool only

Kalau 1 year drill less than 10 holes, dont buy cordless apa lagi rotary, tidak balik modal one.

The new GBH18-26 very gooding la comapred to my wired HR2470 and GBH 18V-LI. Sudah balik modal many fold liao I wonder how much would ppl charge to do these ooo.

It depends.. I also like to take up same building (that I stay in) punya small job like hanging picture frame wall plug drilling coz almost every wall is concrete/AAC block A couple jobs paid off the GBH 180-LI' you recommended me earlier on

Stay in condo walls. I have 3 windows and balcony to drill for installing blinds

But expensive tool, drill 1 hole in 5s and got everything done in no time, customer said, "Wah, so expensive. Easy job only"

So, need to delay and make it slow and steady

Some condo very tight timeline, only can drill within 9am-1pm so every minute saved goes a long way to complete the job in time

Hi sifu sifu sekalian, i need some advice in getting a table saw.
Advice not in term of which brand to get but is it suitable to operate a table saw at the car pourch of a double storey terrace house? Will it be too noisy and get complain by neighbor?

Noise cannot do anything. You make noise, then neighbor make noise. So, even So depends on neighbor. Probably just don't start working at 7am

Many small size table saw to your requirement.

Hi all.. would like to ask for opinion. Is this brand better compare to Bosch?

or any other recommendation.

Sorry i do not have any knowledge of power tools but plan to buy as a gift.


Thanks alot

This is one of big name for the US manufacturer. Bosch is German. In general, this brand is more expensive. I'd say both are comparable.

I have a table saw too, as long as you don't run the table saw everyday 9am to 9pm I think your neighbor should be fine with it.
I only use my table saw occasionally as I just a hobby DIY user.
