Newbie question about drill bit

Caspero

So I'm one of those people who never did DIY and just learns stuff occasionally by googling it. This time however I don't know the name of the thing I have to google.

I'm trying to drill a long-ish but narrow hole. I have a drill bit of the right width but it's not very long. So when I put it in my drill, then put the bit up against the wall and start drilling, the bit slips back into the drill with only a tiny bit of the bit poking out the end.

What part do I need to get to fix this problem? Is there something that I insert into the drill like a little bit of metal that will stop the drill bit from slipping down into the drill? Or something else?

Any help appreciated.

With all the hassle of it you might be better to go get a longer bit if you are close to one of the suppliers. I often drill tiny holes with short bits, just tighten the chuck as much as you can. I would suspect it is something soft you are drilling, wood or aluminum or plaster?

Thanks for the help folks. Yes the width of the drill bit is small so yes having a tighter chuck would work. It's a hand closing chuck rather than a key chuck.

It has happened on different surfaces, plaster but also masonry. Especially happens when I turn the hammer action on.

Yeah the bit length is short, it came with rawl plugs that I'm using. Maybe I can go back and get longer ones.

I was reading a bit since, would an extension like this be an option aswell?

Can I ask what it is you are trying to drill a hole in? Very few tiny bits cope well in concrete especially on a hammer action.

Thanks TT. It's the wall next to a window - putting rawl plugs / screws in to secure a fitting which used to be holding up blinds but fell. First part is soft (plaster) but then I think I hit brick fairly quickly because I feel resistance...until the drill bit slides back.

So when looking around, many of these small width drill bits look fairly short. Also this is the bit that came with the actual screws I'm trying to install.

Some pictures to describe what I mean in case there's something I'm missing or not describing properly:

The wall I want to drill into (ignore the rawl plugs shown)


The length I want to use for my drill bit


What ends up happening when I start to drill

Looks like your chuck is not tight enough on the bit or not working properly. Loosen it slightly, Grip the chuck with your hand and pull the trigger on and off. Dont push too hard against the wall when drilling and let the hammer action do the work.

And if that fails you can buy longer similar sized masonry bits from most outlets. Is it a stone wall with plaster on the inside?

Thanks for the tips folks. I did try tightening by holding the chuck and pulling the trigger. I reckon I'll end up getting longer bits. Just before I do -has anyone tried a drill bit extension for this type of situation? The drill holds larger bits fairly well so I was thinking if the extension had a tighter grip on the bit, maybe that would work.

Yes it is

longer bit as the extension piece wont really tolerate the hammer action that well

Happened to me once that the screw inside the chuck had fallen out.This allowed smaller bits to slide further into the chuck than designed.

For drilling into things like stone and dense concrete lintels etc. you really need an SDS drill and bits. Cheap these days from Lidl/Aldi and well up to DIY use. Most 'hammer action' drills and 'masonry' bits are only fit for going through plaster and brick - most brick is quite soft. The difference in price to get the proper tool for the job is now small but the difference in performance is large. They come with (or you can get) a chuck adaptor to use non-SDS standard drill bits, some also have a 'chisel mode' (percussion action with no rotation) for knocking old plaster and tiles off walls, etc.

I was drilling holes for skirting boards in my (late 60s, concrete block inner walls) house and had a very hard time putting the first few in with a 24V cordless 'hammer action' drill, got a Makita SDS drill on special offer in B&Q and the difference was night and day, 5 seconds to drill a hole that took 5 minutes (and blunted the bit doing it.)

Thanks for the recommendations folks!

I looked at mine and there is a hole at the end where it looks like such a screw might have fallen out. What do you think folks - is this the problem? Photo here
