21Mm Hole

[bainbrig]

I want to put an HDMI Cable through a brick wall. The cable is 21mm wide at its widest.

If I use a 20mm masonry bit, will there be enough ‘extra’ to wiggle the HDMI cable through?

Possibly

Is it just the cable or are there connectors on the end?

Hard to say. You could try to ream out the hole a bit by moving the drill bit in and out whilst tilting it from side to side. Possibly washing-up liquid lubricant would help when inserting the cable.

[bainbrig]

It’s a standard HDMI unit - the cable is only about 10mm - it’s the INTEGRAL connector which is the 21mm.

I suppose a really skilled person could cut and resolder, but that ain’t me.

I think its well likely, knowing that masonry bits and hammer drills tend to leave a little wriggle room.
How about a test hole on a spare brick ?

[bainbrig]

Thanks atheist - yes, the w/up liquid is a good trick.

There's the way to go from chipchopper

Simples - test hole

Thanks chipchopper.

Personally I'd use a 25mm core bit. Which is what I did do for mine.

Maybe best to blow the hole through before adding lubricant so as not to clog it. A bit of tubing and some puff; or suck with a vacuum cleaner.

Are you sure it's 21mm?
That seems to be very large for an HDMI cable.

Or drill two 10mm holes side by side so you end with a slot

[bainbrig]

Well, measure one - as I said, it’s the end fittings that (I think) are 21mm, not the cabley bit.

[bainbrig]

Fitzer. 2 holes as a slot might do it, thanks.

(And I’ve just re-measured - it IS 21mm, I’m afraid!)

[bainbrig]

25mm is a very hefty bit - not sure it would get into my drill...

[Fitzer]

As said masonry drills are always a little bit untidy so a little bit of wiggling on two 10mm holes will easily give you a 21mm slot

[Old_Geezer]

Wriggle the drill.
Or file it slightly wider.

Adding stuff like Washing up liquid would with the inevitable brickdust cause a paste clogging the the terminals. No WU liquid at least you could blow the dust out of the plug.
