I need 4 holes on the wall for a bracket mounting, the 1st hole can be anywhere, but the 3 other holes need to follow the 1st hole and need to be extremely accurate or the screw will not fit, from my experience its difficult for me to drill the hole so accurate, can have only +- 1mm variance for mistake only for each hole.

How to make such accurate drilling ? drawing circle on the wall is easy, but once drilling starts, the drill bit will some how "move" a bit if certain part of the wall is harder, how to prevent the bit from "moving" ?

Lol

Use manual hand drill. The slower the drill, the more accurate u r.

use laser drill...

or do pilot drill

Use makita/bosch rotary hammer wont have problems with 'move a bit'.

Also new drill bit.

use punch tool 2 mark a small hole, y u no experience need a virgin help

ingat drill benda lain...sigh

make a wood jig.. drill 4 holes with accurate location on it.. then drill the first hole to the wall.. and use the jig for the other 3 holes.

use a spirit ruler.



use this to level and mark ur holes.

during drill time, use a slower speed to mark the hole and then speed up and punch through

if u want to prevent the bit from moving,

just put masking tape on the wall.. when the drill tip hits it, it wont move all around.

use sniper scope

Take a nail and hit it at exact spot of the center of marking. The use small size drill to drill a small hole.
After that only drill the hole using the drill size that you wanted. You could skip that nail part also

+1

Bosch multi purpose drill bit not bad…you can get from ace hardware.

Btw, if ts scare 'move a bit' then use 5.5mm drill bit first instead of 6mm

you need the hole to be same size or slightly bigger than the "pipe" on the plug, and when hammer it in, loosen the nut, the hole need to be deep enough for the entire "pipe" plus the head of the screw to go in. i am installing these too, i purchased item that come with low quality anchor wall plug, and im changing them to something bigger, more reliable, its not that difficult to put them in. oh btw dont make the hole too big, or the wall plug will be useless.

draw the 4 holes on paper accurately, then paste the paper on the wall. drill through paper. win liao lor

rotary hammer is not a good option for drilling tiny hole. Better use regular drill, turn off hammer action mode if possible

For better accuracy use a small bit (4mm) first.......use the correct bit size on second run

Use a self-piloting bit and set to lowest rpm.

And a firm grip helps too.

condo has weak walls, cant compare.

Masking tape to mark where you want everything accurately, then start for the smallest bits and then move up to the size you need.

Usually I don't recommend using a pin punch on walls due to the possibility of flaking paint.

use drill tiles punya drillz head drill a bit 1st

i think u buy pull up bar ,

i also ,

my father use spanar hole as washer to beat the circle foreskin , slowly by slowly.


only can go in ,

i make alot of holes , but failed ,

i as a beginner of drilling ,

my father very tarik harga , and like sindir people ,

finally have to ask him to do ,

i would have call the welder do if not my house full of pets ,

4 hole each side , both side 8 total ,

my father managed 7 of 8 holes , while i manage none ,

ask the welder do is more worth , i dont know wasted how many wall plug...........................

drill slowly, once u entered ard 0.5 cm, can accelerate

First you knock down the wall.

Then you hold the bracket mounting. Hold it in position.

Once you done that, you ask the Indon to start laying the bricks, apply the cement and wait for it to dry.
NOTE: Don't let go of the bracket. Very important.

And thennnn, ask him to plaster. Ask him to be careful. Don't plaster over the bracket.


Deyyyy... if the hole is big, you start with a smaller drill bit first la... you straight away use the big drill bit confirm you will miss the mark. Sometimes I use up to 3 drill bits to make it precise.

i heard last time ppl use human skull from a very stupid human in construction so that the final product can last longer, i need your skull, so i that the wall plan you describe can last longer.

Drill hole in the wall so hard to do meh?
Anyway the good suggestion is using masking tape.

To drill 4 holes for a shelf, start by drilling 1 hole.
Position the shelf and screw about 80% of the way.
Mark another hole on the masking tape and drill.
Insert wallplug and screw.
The last 2 holes are easy. No need to mark, just drill away.

Kasi photostat the thing u wan to hold on to the wall. The tape it on the wall. Drill on the exact location.

Woooohhhh k.

Will I die??

This wan. Tile drill head won't move about, use it to make a small hole, then tukar drill bit to the normal one.

jibby say you wont.

I think it is impossible to make it super accurate unless you drill it through the mounting holes.

i was thinking bout this too, drill the 1st hole, mount it tight, then from the bracket hole, start drilling, but will damage the drill bit and make even more noise as the bit hit the metal instead of just the wall.

Eh you don't need a drill bit the same exact size of the bracket hole. Always go for the smaller bit since the final drilled hole is always bigger than the drill bit (due to vibration).

you need directional drilling to be accurate
