How to remove protruding metal around hole after drilling

[DIYpowered]

Hello,

I am a DIY'er and i bought some stainless steel wall hooks. The problem is that those hooks do not have a hole to put a screw through. So, i bought a metal drill bit and it worked except that on the other side of the stainless steel plate, there is now a protruding part around the hole which i would like to shave off. As it is right now, the plate does not lay flat against the wall due to the protrusion caused by the drilling. Is there any easy way to shave off that protrusion without having to buy expensive equipment?

Below are some pictures of the drilled stainless steel hook


Thanks for any advice!

Use a slightly bigger drill bit, apply just enough pressure to cut the burr off.

I think that it is risky - it might just drill a bigger hole. I'm doing it all by hand with no clamp or machinery. Also, i do not have a bigger drill bit. I previously purchased a 5mm metal drill bit only for this work (just big enough drill bit for the screw to pass through).

I am thinking about purchasing a metal file? Maybe for delicate work, this is better? But what kind of needle file (flat, triangle, round, etc)?

The recognised way is to use a larger drill bit, as per freddie above.
Use a much larger drill, hold it in a gloved hand and the burr will be removed.
Failing that, just buy a flat second cut file and use that.

OK, i will buy a bigger metal drill bit. I have used a 5mm drill bit to drill that hole, so what size drill bit is recommended to deburr in this case?

Here is the packaging (at the hardware store, they advised me to get this one):

If you have a pair of wire cutters or another tool with very square edges and a tapered point use the point to debur. A file tang could also be used, in fact anything that has been hardened and is tapered with square edges that will go through the hole.

I'd follow jj here, but many of us will have dozens of drills around. A suitable size would be around 8mm but there's no need to buy one specially when other items would do!

Haha that tub of dozens of old knackered drill bits I still keep just in case, I don't know why I keep them.

An 8mm hss drill bit from toolstation is £3.58.

If you want to use a file then I'd use a round needle file personally but I'd imagine one will cost more than the drill bit.

A countersink bit will do it.

The DIY sheds sell them for woodworking, but it will do a few steel holes without wearing out

You only need to shave off the burrs.

Simple 40 grit sandpaper would do it.

Thanks for the suggestions. Much appreciated!

To be honest, unless it's tiles, that'll just bite into whatever background your screwing it to and give it a bit of extra hold.

Maybe not so great if they're using a plastic wall plug.
