How to drill holes as close to a wall as possible?

[Elnovis]

I should have asked the craftsman when he was here how he drilled holes in the walls (for electrical cable) right next to the wall, but I forgot. Can someone tell me how to drill a (about 10 mm) hole right next to the wall? The problem is that the drill itself forces the bit out, creating an angle.

One measures and drills from both ends. /rörmokarn

 

[Elnovis]

You measure and drill from both sides. /rörmokarn

So it becomes an angle that meets in the middle of the wall?

 

[Dr.L]

So it becomes an angle that meets in the middle of the wall?

Yes, in principle. Therefore, it is advantageous to drill slightly larger than what you really need.

Do you mean like this?

Yes, that's how you do it.

Then it helps to choose a machine whose construction is such that you get the smallest angle possible. Eccentric head or angle head can sometimes make it easier.

With a long drill, depending on its size, you can also bend it slightly while drilling. This way, you avoid drilling from two directions

"Real" craftsmen have taken the time to have special drills made by welding a stainless flexible rod in the middle of the back of the drill. Or buy ready-made form drills. In this way, you can place the drill against the wall and with the bent rod have the machine a bit out. Then you get a nice hole straight through.

I remembered a unique drill brace I saw in a picture once. It might work for the purpose, but it may not be something easily available today.

Yep, in the USA, so-called flex bits that are very flexible are also popular. They can be ordered from, for instance, Amazon and eBay. With these, you can get into edges and corners and still drill straight.

Came to think of a different hand drill I saw in a picture once. Might be able to work for the purpose but maybe not something that's easily available today.

Ratchet brace can still be found nowadays.

Festool with eccentric chuck.

 

[skogstomten]

There are different variants of angle chucks and those with side displacement towards the edge.

Festool with eccentric chuck.

Why specifically Festool?
