Okies I did hammer it light to make some dent on it then use it as start point to drill..Later will try again after I buy the ceramic drill bit.

Use ceramic bit. Run slow and drip a bit water during drill will help preserve the bit. Never use impact for tiles.

Okies, impact just wall the wall / cement right?

Yes.

Wood, tiles, metal and plastic no impact.

Run slow so less heat build up on bit. cold bit will drill faster than hot bit.

I use a philip screw driver to make a dent before using masonry drill bit. Drill in in drill mode when on tile and change to hammer mode when it hit cement. I did encountered once where the tile not a porcelain tile. Need
and keep on cooling the drill bit.

Tiles are very hard, they need to be scraped off bit by bit using tile bit (run in normal mode at slow speed without impact). Hard but brittle, so do not use impact, else the tile can crack.
This is where the GSB120 excels, use on first gear only when using tile bit. It will take around 5 mins to scrape through one hole. Slow speed and dip dip the bit in water will prolong the lifespan for tile bit.

Usually I will use the CYL-9 from bosch: https://shopee.com.my/Bosch-CYL-9-Ceramic-E...4764.2342546053
If you have many tile holes to be drilled then can get a china bit bulk pack, they're much cheaper than bosch ones as tile bits wear out pretty fast: https://shopee.com.my/10pcs-Drill-Bit-Glass...6352.2160941573

Once you go through the tile then you can continue hammer mode on the wall bricks with standard masonry bit. Cheap one and expensive one works almost the same for the round shank type of masonry bit. Masonry bit you can use either 1st or 2nd gear setting.

Anybody has encountered problem with Bosch cordless drill whereby the battery just failed to be charged (the charger light was continuous indicating rhe charging operation is not running)?

At first I thought I got a bad battery and charger, so I change to a new battery and charger. At first it was good, but few days after the battery failed to charged again. Fed up, i change to a new battery and charger.

I suspect something wrong with the drill making the battery bad because even after I change to a 3rd battery and charger, after few usages the battery cannot be charged back.

It's weird. Anybody encounter same problem with mine?

which model? does it turn freely? make sure its in gear properly (fwd/rev) n speed setting need to click properly, if halfway it may short out

I have never had this problem and I don;t own a cordless Bosch either

I can think of a possibility. I guess your drill is not brushless type. Probably due to wear and tear whatever, when the drill is off the motor stop in condition that shorted the power. Current probably not too high to operate the drill but discharged the battery overnight. Probably you need to open up the drill and clean the commutator. Not sure if your model is carbon brush replaceable type.

The Lithium battery usually has small circuit board inside the battery to cut off the power once the voltage is low at certain level. If the voltage goes below this level, it will fail to charge and deemed as useless or damaged. That is why Lithium ion battery is recommended to store at half voltage to prolong its life. and recharge when charge drops to about 20%.

As for the battery, there are video on how to revive dead Lithium ion battery on YouTube. Google for it.

It was Bosch GSB 1080-2-Li.

I have ensure the setting is correct on the fwd/rev function. It was working fine last week. Then i left unused for a week with rhe battery attached and when tried to use yesterday, it wasnt working. The battery wasnt even charging hence i conclude that the drill is making the battery faulty for some reason.

I'll try to google it bro. Thanks.

Lithium battery have and need bms board to avoid overcharge and over discharge.

I am not sure how the current bosch bms function but for your case, just remove the battery from the drill during storage.

Btw you can diy replace the internal battery. Just use high discharge 18650 battery. About RM20 for a battery.

Im sorry but what is bms?

Battery management system aka the circuit board use to manage charge and discharge of lithium battery.

The Allefix has variable speed and quick release

However, I don't know if it is compatible with any blade from known brand

thank you ....

allefix really good price ...wonder it compatible with all blade ?no matter china or local ?

those china brand cutter no good ?

mostly all oscillating cutter has variable speed control right ..
quick release safe to use ? will accidentally press the button to release the blade ?

thanks ...

The variable speed at that price is impressive. That's all. Mine already old model Bosch GOP CE250 if not mistaken. Just single speed and cost like around RM500 last time. Not many in market that time I think even China one.

Honestly, I don't know when you need to slow it down Being oscillating fast back and forth, it makes the tool more stationary and steady.

I think the quick release is good, less hassle changing blade like mine. The quick release lever/button position is at location where you don't hold your hand during operation. I believe it is safe to use.

The blades for different brand are different and even Bosch has new series that will nor work on old model like mine . So, need to read carefully and also confirm with seller for compatibility since seller just copy paste ads that might not be accurate. The cheap China blade sometime colored black like carbon steel but actually just painted black Anyway, the Bosch blade that I used also did not last that long

I tried to find info on Allfix blade but not where to mention which brand is compatible with it. That is my main concern.

good ....lesson learnt ...

need to ask seller others blade compatible with the allfix cutter or not b4 place order ...

otherwise..bossman good too ..come with storage box..


thanks ...
