Grinder must be operated at full speed (spin up) before cutting.
Make sure to give it 3000% respect. No distraction. Must wear PPE and hold it securely with two hands, blade guard always on. Clamp down workpiece securely. Use good disc. Throw worn ones. Be very careful w cutting disc (the thin ones), make sure u cut straight and not warping the disc; the grinding disc (thick ones) slightly safer. Cut slowly when ur new and ensure the disc still spin fast, when its fast it wont jam. If it bogs down (too slow) it becomes dangerous. My stance is NEVER cut wood w grinder, only metal or stones. Circular saws are not expensive and much safer as they rotate to grip the workpiece. I forgot ur is cordless or corded..if corded make sure to place the cord in a way u dont trip over and it wont cut the cord.

It will have kickback the moment you turn it on. I think its an inherent thing with grinder. Use with handle, if no handle buy one..i added handle for my GWS060 basic grinder.

I've heard bangla dancing around avoiding runaway grinder in metal foundry before.. had to overcome my fear of it coz needed it for job. After use few times u will get used to kickback. Maybe u practice with thick grinding disc just polish a few bricks or AAC block first..before upgrade to cutting disc.

Alternatively a safer tool is the multi tool (osci cutter) or the sawzall. Blade memang expensive but much safer if you don't need a grinder per se.

Ahh now we get your true meaning. I thought Total bought over DCA earlier.
Now its a matter of shop just changing to focus on selling Total stuff hence clearing inventory of DCA stuff.

It is a very good price for the DCA rotohammer. Too bad I already have two rotohammers lol

Should be good We don't really use grinders 8hrs nonstop, so even the GWS060 works very well for our purposes.
What would be the cutting scope you're intending to do?

12rent.com.my
Depending on what tool exactly. If rotohammer buy the clear stock DCA abovementioned, cheaper than u rent 2x.

Located in puchong

From 50 bucks a day also got.
But u need to collect in KL or Klang apparently.

Should be reliable enough. But if wanna "condemn the disc" on concrete cutting chases the diamond edged ones are much cheaper. It should last damn long if you're cutting metal being a carbide blade.

⚠️ Cutting plaster board with grinder will produce a Desert Storm kind of dust cloud ⚠️

For that a GOP multitool works much better. The dust drops instead of Desert Storming the whole floor (in high rise)

Do not drill within 2in clearance vertically of any outlet coz obviously pipe will be there.. u offset ur fittings accordingly lah. Else will be a mess (hack tiles) to fix leaking concealed pipe.
Stick two lengths of masking tape up from the outlet or tap so you will not miss the NO DRILL ZONE.

Got pic? Worst case, use sth like aluminum flat bar make adapter bar so that it can still be affixed to wall but not being drilled at critical zone. Liquid Nails will stick but if there is movement from day to day use it might drop off one day..

Yup multitool much safer and easier to control.
Bosch GOP18V-28 EC very nice to use. Low vibration.

Lol actually if you dig thru I think most of the regulars here already have a multicutter..

Got 3M ear plugs.

Bosch should carry - pos 651 https://www.boschtoolservice.com/my/en/bosc...25-l-3601GA30L0

However, it seems that there's more than just changing the guard alone..also need the associated M14 parts..

Close to useless on concrete tbh. You'll be vibrating the neighbourhood for 30 or 40 mins at least. Those impact drill are only good for brickwall.

Any SDS+ rotary hammer will do it in seconds. The above DCA clearance is a very good price. When you use it, it will put a smile on your face.

No prob.. rotary hammer also does make your holes more pro because its effortless to drill wall plugs, the holes will be straight (just hold it firmly with 2-handed grip, and let the machine do the job).
Impact drill need the user to lean into it.. and thats where the holes start to become S shaped and hard to insert wall plug properly. Comparing that 119 to a 100-bucks "toy hammer" impact drill is night and day diff..if you're in town (Klang Valley) its really worth to get.

Basically the diff between the round shank bits' "toy hammer at 40k bpm" vs SDS+ keyed bits "real rotary hammer with Joule spec" is in their hammer mode for masonry.

In terms of normal drill (rotate only) no difference. Just that SDS rotary hammer using SDS+ keyed bits, its primarily geared for masonry purpose..so u will need a chuck adapter to use round shank bits (wood/HSS) on a SDS+ machine.

In terms of longetivity of masonry bits..Due to the fact the runtime is shorter per wall plug hole (5-6sec on SDS+) vs (1 min brickwall to 10min concrete on round shank), SDS carbide bits are very economical to use. Easily 60 to 100 holes per bit. U often hear masonry round shank bits botaking fast

Depends on which wall plug ..speaking from exp from the red box wood plugs
5.5mm for the skinny #8 plug
5.5mm snug fit for #10
6mm for #10

Hahaha terbeli syndrome is real. I thought Hikoki makes pretty legendary nailers?

Low end bosch drill driver (GSB180) plastic chuck lari, not true centered. A bit annoying for screwdriving.
In the same drill driver family..Luckily the GSB 18V-50 metal chuck very true.. and brushless can be abused for nonstop hours drilling (drill 4x 6mm holes in floor tile took the good part of 8AH procore) U never believe it until u saw it..4 holes alone can flatten 8AH worth of power

China can get very good things grade A.. but they also can make grade B, C, D, F as well..

Bosch Q4 2021 got free battery with 18V tool purchase.. so I TERBELI just to TERRECEIVE the free 18V 4AH

Makita also very good but price went up like 20-25%
---

I've also noticed my grille installer (Threekim) also use Milwaukee

Bosch also got Hungary made (the multitool)..
