i am a not-so-casual DIY but this tools sufficiently helps me in hanging household item

BOSCH GSB 1080-2-Li

its a cordless drill with hammer function, so far it serve me well to hang my TV, 8ft mirror and toilet storage racks.
for low speed and high torque, I switch mode to screw driving mode for other DIY jobs like study table assembly, cabinet assembly and some other wood stuff
*
assembly, screw driving = ok

i think normal plaster wall with bricks = ok

if its drilling a hole in concrete wall = no

i am using this for normal installing works and screw driving, and its still rather big to handle ...

for my curtain project - i got the Makita HR2470, makes the concrete wall look like tofu ...

concrete wall can but takes longer time because of the bpm is less compared to electrical corded drill
for me, as a user that drills concrete wall once every 3 years or maybe 10 years, i just go with it.

hahah true ... but standby several drill bits lo

Quick question on some drilling I have been doing lately with my makita rotary hammer

I made several drilling for my curtains with the 6mm drill bit and use those 6mm anchor plug

I realised of 10 holes... Very likely 4 would be quite huge and the anchor plug would be too loose to drive any screw in

Is this because when I drill I move too much hence the bigger drill hole?

Should I use just rotary without hammer? Or get some. Bigger anchor plugs? Not even sure if there are bigger ones

So far been able to mod the anchor plug a bit to fit...

What did I did wrong here?

my method always using a step smaller drill bit than the anchor or wall plug size...can try with 8mm plug
*
so there are bigger plugs available, will go source for them

so far i been stuffing some of the spiled anchors bits and pieces into a new anchor and is able to be used to drive a screw in ... i guess having the 8mm anchor will be great

One more questions, if i am installing hanging lights(not heavy ones) onto the ceiling, should i use back these plastic anchor plugs or use metal ones?

Sometimes I have that problem. I solved it by using 5.5mm drill bit. Problem settled.

hmm a 5.5mm drill bit? but some of the holes will have no issues with the 6mm drill bit ...

i think i moved too much when i am drilling ...

It is not so much about u moving, it is more of as a result of the rotary drill movement. U use rotary drill and that drill moves by way of knocking together with screwing/drilling and that causes the holes to be a little bit bigger than it suppose to be.

Sometimes, it is about the concrete side, some with too much sand ingredient, easily chip away, hence the hole become slightly big and anchor pin become a bit loose.

Just like you hammer cement using a nail, everytime you will get slight different result.

Normally I use undersize drill to test out first.

Will go source a 5.5mm drill bit

and i noticed that the sound of the rotary drill changes when it hits a hollow wall, was thinking something wrong with the drill, but found out when it hits hollow point, the sound changes

Drilling a big hole can really put the powertools to the limit.

Try drill a 125mm hole. 1st using the Bosch GRE16RE 750W. It struggle to drill and getting very hot. Almost cannot touch the motor body. The hole cut deep getting no where. Afraid it get spoil, I stop using it.

Change it to Makita HR2470 780W. Drill like a charm. Less effort to push. And speed more constant even pushing hard.

Despite the watt almost same, (different by 30w) Rotary drill are much more powerfull than hammer drill. If doing some big job.
