Help me find the right drill bit please.

[NRS]

I need a 3.2mm drill bit for tiles. So I guess diamond tipped? It’s to put up a shower screen.

I cannot for the life of me find a 3.2mm drill bit for tile.

Help?!

Why does it need to be 3.2mm diameter? And what are you going to put through the hole that is thinner than 3.2mm?

6mm diamond bits for drilling tiles are common, I really recommend those which attach to a grinder over those which go into a cordless drill

An ordinary masonry drill will handle ceramic tiles. NO HAMMER though.

3.2 seems awful small though: surely you're going to use wall plus so at least 5mm for yellow plugs

These are the instructions. It’s a shower screen. I took this to mean a 3.2mm drill bit.

A 6mm bit would make more sense. But what’s the reference to a 3.2mm

You'll find it even harder to find a 3.2mm plug!

Drill a bigger hole to suit the plugs you will use

Probably 3mm hole thru frame upright , it mentions 6mm for hole in wall.

I mean, the instructions really do make it look like they want you to drill a 3.2 mm hole in the wall but it’s a ludicrous level of precision for a hole in masonry, that doesn’t even make sense, because you’d be fitting a 3mm plug with 1mm of plastic around a 1mm hole and then driving in a 1mm screw. To hold up a shower screen? Clearly absolute nonsense that would see you wearing the screen/it in bits on the floor

I’d expect more like you use a 5-7mm bit and plug to hold the mounting channel to the wall, then you drill a 3mm hole in the channel and screen edge and screw in a self tapper, after you’ve arranged the screen so that it’s plumb; screens often come with a U shaped channel that goes on the wall first and grips another metal bar running down the side of the screen, to allow the wall to be slightly out of plumb/squate and still mount the screen with no gaps
Because these channels are designed to take out deviations/varying degrees of out-of-plumbness they cannot be pre drilled in the factory

For example:

The yellow highlighted channel goes on the wall first with a larger plug, then the blue highlighted part of the screen is slotted into it, the screen made true and square and then a small hole drilled eg at the red dot location and a screw wound in to stop the screen falling out of the channel


Don’t stress about 3.2mm - get. 3; the self tapper will wind into it fine. Feel free to post a picture of everything that was in the package so we can check

The 3.2mm bit is to make or enlarge a hole in the metal structure of the shower screen. Makita do them in hss steel. It’s probably for a 3.5mm fixing.
