Tool for calculating where drilled hole will come out

[john2k]

Might sound like a silly question, but does anyone know of a tool that can potentially send some sort of wave and measure that on the other side to accurately determine where a drilled hole will come out of? I know measuring works but in some cases measuring is very awkward so a tool that does this would really come in handy. Not seen such a tool but checking to see if anyone else has?

Thanks

Very much doubt it exists.

Hole through what?

Not for a DIYer I would think but handy if you have a lot of that sort of work

Just drill a small test hole and fill and decorate when no longer needed.

Expensive but cool.

Would be wayyy more cool if it would let you drill at an angle and let you determine where the hole will exit.

I have had jobs in the past where I had to drill through a 9 inch wall and make the exit hole come out at 45+ degrees lower than the exit hole. I would love to see a tool that does that.

It says it does that too.. I'd like to know how it works?

My bad, thanks, yes the second video in the link shows the angle plate attachment.

Mind you, it can be hired for £44 per week (ex VAT).

If you know the width of the wall and angle of drilling you should be able to calculate it?

True, but that means using trigonometry, which many may not be familiar with.

Wow, thats a clever bit of kit

plenty of triangle calculator apps available these days for android and apple

a must for carpenters

I use one quite often
