Drilling wall tiles
My experience using CYL-9 spade bit lasts long, almost 15 holes before it botaked. Ok la for RM16
Then tot can save money using the normal CYL-3 multipurpose (got wall tile icon) drill few holes then botaked. Only fit to drill wood afterwards.

Even though I just use it to drill thru the tile, and after I hit the concrete I switched to SDS masonry bits to rock and roll w rotary hammer

Concrete wall no problem up to 24mm hole.
You will need SDS plus bits for masonry for the rotary hammer function, plug and play.
Normal staright shank bits will need a chuck adapter.

Gaps between tiles normal masonry bit will do. I believe its best to drill on rotary only until you have passed the tile thickness, once you hit the concrete below you can use rotary hammer mode.
Drilling on tiles you need the tile bit aka CYL-9, use on rotary only (WITHOUT hammer) mode at slow speed. These bits are straight shank, need to use a chuck adapter.

Chuck adapter.. u can get gooding ones from Hitachi here https://www.lazada.com.my/products/hitachi-...ivtTdj&search=1
comes with a whole bunch of SDS bits and one chisel. Sounds like a good deal.

or the chuck adapter only - super cheap https://www.lazada.com.my/products/hitachi-...l__null__null__

Concrete wall or brick wall (clay/sand brick)?
Brick wall any 12V bosch or makita cordless will do. 12V tools below 400 drill+battery+charger

Concrete wall need to reevaluate options as 18V drill/18V rotary hammer costs more.

Yup this will work fine. You might need to buy drill bits for it. SDS plus bits will be plug and play.

A lot of good-brand bits going cheap online nowadays from Bosch/Hitachi/Makita as well.

Yeah around there. The tool is not expensive but after adding battery and charger it costs more.


Bosch GBH 180 Li - https://shopee.com.my/COMBO-Bosch-GBH180-LI...7548.1559405712

Makita has more range (need to see see). Offerings on shopee not that great (suggest to consider batt+charger price as well as solo unit price)

However of late (2019+) I noticed shop contractors starting to use cordless tools though.

For DB box (i.e. electricity turned off) replacement I will need to drill 4 holes to install the new DB box.
However the wall is (I suspect) 25-30 years old concrete wall which I don't think a cheap cordless impact driver on 12V will make any impact even for 5.5mm hole size
Cost of 18V rotary hammer is too high for a whole set

I think best to hook up my corded rotary hammer (2-24) from next door neighbour.

Just ordered solo unit GBH180Li at 399 and the battery + charger separate.
Funny that the parts total (split separately) is still much cheaper than those all-in-one combos.

Flexibility and no need to worry working hot with live wire, can off the whole DB box.

Got. The 7/8" SDS (3 mode) 2605-22 would be the rough equivalent to the GBH 180-LI.

Some comes with lower tier battery and costs more

Mine I got it all separate, all prices before discounts and vouchers
GBH180-Li solo with hard case RM395
GAL 1860 CV fast charger RM105
Core 4.0Ah battery RM280
Subtotal RM780

vs all in one:


BOSCH GBH180-LI C/W 1x 3.0AH 18V BATTERY (normal battery) + GAL18V-40 charger (ok la compact charger but slower charger) RM810

BOSCH GBH180-LI C/W AL1814CV CHARGER (slower charger) + 1NO 18V 4.0AH BATTERY (normal battery) RM828

I tot all in one should be cheaper than buying piecemeal

But the problem is that I think Makita got too many overlapping product that its too hard to buy (hard to compare).. imagine Myvi launch with 1.0 1.1 1.2 1.3 1.4 1.45 1.5 1.6 1.8L engine especially cordless driver/rotary tool. And their website not that user friendly to compare all in one category. So that can map out a price/performance value between the price of product (eg on shopee) vs the features (BL non-BL, 2 mode 3 mode) etc.
Mau beli cordless rotary, keep on seeing that electric jacket search results

One thing, even abrasives (sandpaper), beli bosch punya mahal but can use until botak.
Buy cheap ones, all the sand came off within 10 passes of sanding down my wooden countertop

From 4mm up.

https://www.lazada.com.my/products/maju-s3-...null__null__0__

From 5mm up

Theres also a set of hitachi sds bits + chisel + chuck adaptor for 18 bucks. Funny how the whole set of stuff is cheaper than standalone bit set.
https://www.lazada.com.my/products/hitachi-...l__null__null__

From 5.5mm up, I find the 5.5mm very useful for wood plugs.

I saw a GSB 180 LI (w batt and charger) at RM330 Shopee link
The bare tool is RM190 only but you will need to source a charger + 18V battery (IMO the set is cheaper to start out with) Shopee link bare tool (SOLO)

GSB =/= GSR
Easy way to remember, GSB can Bang wall (got impact)
GSR can Reverse, no impact

The 18V batteries are interchangeable within all the bosch 18V tools. Of course some tools will recommend a bigger battery for heavy duty usage but it'll still work.
Cordless tools, the brand (i.e. the battery system) is the one you are investing in.
The tools are cheap, but the bigger batteries cost more. The cordless rotary hammer GBH 180-Li cost me only RM399.15 (excluding battery and charger)

True that. I invested in bosch 18V system because my place has hard concrete walls.
So far I have the GBH-180LI rotary hammer and ordered a GSB-180 screwdriver (coming soon for screwing the kitchen cabinet).

12V tool the advantage is lighter tool

Makita tools cheap or comparable with bosch for the cordless drill driver..
But the battery and charger macam more expensive
For first time cordless tool investor it didn't make economic sense to me, so I kinda got stuck with bosch 18V

Although I saw that makita got coffee maker and powerbank that runs off the battery (MAKITA ADP05 BATTERY ADAPTER FOR USB 18V (C/W 2PORT) PHONE CHARGER POWERBANK)
Unfortunately didnt see any cheap bosch battery to makita tool adapter. The other way got (makita battery to run bosch tool) but kinda hampered a conversion to use the makita powerbank lol

I think it also depends on how many cordless tools you'd need as well. Me I think I dont need much more than the cordless rotary hammer and impact drill driver;
maybe add the LED light or impact wrench (nice to have but pricey over long iron pipe to open tyre nuts for self rotation every half year).. maybe useful for jacking up the vehicle using the scissor jack but then again, nice to have

It depends on the usage rate:
Less than 12 holes per year you can buy a Bossman rotary hammer for RM165 (pakai buang price lah)
Some usage - RM360 Hikoki rotary hammer / RM319 Stanley rotary hammer
Heavier usage RM438 Bosch 2-24 / RM515 Makita HR2470

If you are just drilling wall plugs smaller than the pinky finger any proper rotary hammer will work great in concrete.

Tile bit you can use your existing GSR120 as the key is to be SLOW (<500rpm) for tiles (NO HAMMER) to avoid cracking. You're looking at CYL-9 tile bits ~RM16 each for 5.5/6mm size

Concrete wall should use SDS+ bit on rotary hammer. Basically for common wall plug size 5.5mm x 50mm long bit will be good for wall plugs. If used with 2" wall plug and 1.75" screw then just drill in all the way no need to mark.

If wanna drill pipe (20mm/ 25mm) holes then consider stanley bits. Got a 20mm hole x 460mm long one for 30+ only. Can check em out Long stanley drill bits

Yeah for bosch 18V can get the cordless rotary hammer GBH180Li + drill driver GSB180Li + 1x 4AH procore battery + fast charger
Basically just over 1k cost, 800 for the rotary hammer + batt + charger, 220 for the GSB180 solo (tool only)

Rotary hammer/hammer drill can use but primarily it was designed as a drill, I find it abit too powerful due to no torque control if using it to screw - often times it strips the screw heads.
Drill driver GSR180/GSB180 or equivalent will suit ur screw installations nicely.

GSR and GSB
R=reversible no impact
B=got Bang function (aka impact drill) but its at best used for brick masonry only. Won't be a good fit for concrete.

Concrete walls best to use a rotary hammer.

The straight cuts and 32/35 mm is like kitchen tap/door knob size +/-
The 120mm hole is gonna be a challenge to cut

#2 Cordless drill driver (GSR120LI) can be useful for screwing and unscrewing whereas normal high speed drill don't have torque control (it will still work, but abit harder to control and you risk stripping screw head if its a long and tight fitting screw). Do note this tool is not extremely powerful for drilling (max about 8mm or so wood plug in brick work).

#1 and #3 here are basic power drills first and foremost, not really suited for screwdriving.

All these (#1-3) will NOT be useful for concrete drilling for more than 1-2 holes of wood plug size - you will spend ten minutes per hole.

Concrete slab aka RC wall aka reinforced concrete, you will be best suited with a SDS+ rotary hammer. Drills in seconds.
You can still survive with a normal "impact drill" for 1-2 holes max (wood plug size) and luck on your side (don't hit a stone or hard patch). This normal "impact drill" will take minutes to drill one hole in RC wall.

Corded one.. can get either makita HR2470 (around 4xx) / bosch 2-24 (around 4xx) / stanley rotary hammer (around 260). Want cheaper can consider DCA/bossman tools, it should work for home use lah

Cordless one.. you will need to invest in big battery (~260 for 4AH) and fast charger (~105), but the tool itself is not expensive (around 350-ish) based on my purchase of GBH180Li solo unit.

The price premium of cordless one is the convenience = no need to worry about finding power socket/extension; corded ones listed above are usually more powerful than cordless equivalent of the same price range.

If the plate is 8mm hole, I assume you will be using some sort of sleeve anchor, max u can go will be 5/16″ bolt, used in combination with a 5/16″ thread sleeve anchor.
Bring the plate to the hardware shop to confirm the bolt thread fits the plate you are mounting.

Hole in wall is based on the external size of the sleeve anchor so you will probably end up with a M10/10mm hole IIRC.

Brick wall can use normal impact drill. Concrete wall is >9000 times harder than bricks so a rotary hammer is recommended - especially if you're talking about using a M10/10mm sized sleeve anchor

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
