I am looking for Bosch 10mm sds drill bit.
Found that sds plus-1 is cheaper than the sds plus-5.
Based on ur experience...which one will u choose ?

I need to drill holes on toilet's tile. 6mm and 8mm hole size.
The bosch gsr 120 gen2 drill power enough to do the task ?
Or do i need to look for bigger brother gsr 180 li drill ?
30 Nm is enough to drill 8mm hole on tile ?
I already have rotary hammer...
I need some advice...thank you.

I bought bosch 8mm tile bit already.
Want to buy cordless drill as it is light and comfort to hold.

My left hand was injured and only can use 20~30 % power.
Rotary hammer is heavy for me at the moment.

Anyway , i have test to drill on toilet's tile with bosch cyl9
ceramic 8mm drill bit. More holes cannot la....
Two holes only is ok for me.Each hole drill 5 to 6 times to cool down
the ceramic bit.
I used normal electric drill 450w which is smaller and lighter for 8mm ceramic
drill bit. Once pass through the tile , then used 8mm sds bit for rotary hammer.

Seems like not only cordless drill can handle the tile drill , normal electric drill
also can do the job as well. The only thing is can't adjust the drill speed like
what battery cordless drill can do....

The branded 12V cordless drill like bosch , makita or dewalt is not cheap ...

You cannot adjust the speed because you bought corded drill with no adjustable speed.

I have 750W corded hammer drill with adjustable speed. I also have rotary hammer for wall, concrete and heavier job when needed. I also have cordless drill driver for lighter job. I used whichever suitable for my task



My old 450w electric drill is normal and single speed type.It is not impact drill.

Last time drill on concrete wall with mansory drill suffer ....

If drlll hole on wall,behind is hard stone , need to press max force ....

The beauty of the cordless drill is tighten the screw with adjustable speed control.

It is light and comfort to hold.

Alot of fun to use the cordless drill.If it is the branded drill some more better.

Too bad the branded cordless drill is not cheap.
Else , can buy one and keep it.
I didn't use it daily , once a while only use it .
