Center drill for masonry?
« on: July 21, 2019, 04:53 AM »
I was looking for a center drill for masonry, for screwing hinges to a outside wall.

I know there is the “tape” trick for preventing your drill to “run off”.

Any reason why there is not (i can not find it) a center drill for masonry? Could you use a wood version and change the drill bit (with same dia)?

Thanks!

Are you attaching hinges directly to the masonry wall, sounds strange to me?

For drilling exact located holes in hard tiles I use one of these. These are rated till 90 Mohs hardness.
They are also known as glass drill bits.
I also use them for drilling masonry because it's relatively soft material compared to tiles or glass.
You can also drill the first centimeter with these drill bits and go further with a normal drill bit.

I have good luck starting the hole in just rotary mode with a masonry bit. After the hole is started, I switch to rotary/hammer mode.

Thanks, thats a great tip, will try that!

Yeah, I should have phrased it differently  :-[ Its not truly a hinge, but a base plate with 4 screw holes (and an "eye" to hook a hammock on).

Yet, the principle is the same. Of course 3 holes where spot-on, yet with number #4 the drill went off a bit. Feel like an idiot, should have used the tape. Yeah, lazy :(

Was just curious why for these applications I didn't see a similar solution as for wood & hinges.

Yeah, I actually always do it like this (good tip). But the "hand-formed" bricks are not flat, and the drill still got away from me [mad]

In the case of when you have multiple holes I drill the first one and use it to anchor the fixture and then use a drill the size of the holes in the fixture as a starting/marking hole for the other holes.
