Drill chuck not adequately gripping drill bit ?

Tried to drill into some pretty tough concrete earlier today. I had to buy a 16mm drill bit, but for some reason, the chuck wasn't getting a good grip on the bit and it kept slipping. I've posted here the drill and bit in case any of you can see an issue.

I've attached a file, but it's not showing?

Thanks, yep, I was trying to attach it, in the exact way I did in my last thread?

That's easy for you to say, since you know what you did and in which thread you did it, I don't.
Follow the instructions to the letter, it does work. (You are not the first to follow the instructions and you will not be the last)
(Also read what any "pop up" message says)

Second try

It's okay, I wasn't expecting you to know how I did it last!

Anyway, I found out that the previous try involved an image was too big (in memory and physical size).

Is it a keyless, or a Jacobs chuck? Why is there a flat on the drill shank, or are there three?

That's better.

Now how about another picture with the chuck in it?

The drill is this one:

Sorry, I didn't understand the question about the drill shank?

A picture of your drill would be better

This is me.

Actually its not, but its still a bloke, see my point? In order to help you specific information is needed, not generic information.

The drill shank in your pic is showing a flat section on what looks like to be just one part of the shank - a three jawed chuck may well struggle to grip that - the flat on the drill bit is effectively turning it into a two jawed chuck - if there were three flats on the shank it shouldn't be a problem.

Thanks ayjay, I think this may well be the issue, for some reason, the drill bit may not be compat with the drill! I will go back to the shop and ask there.

Concrete is a LOT easier to drill into when you use a sds drill

https://www.screwfix.com/p/titan-ttb631 ... 240v/4172g And this has a good selection of bits as well.

You won’t go back to using a impact drill once you have used one of these.

You have to buy drill bits that fit but once you’ve used one you won’t go back to a impact drill. I bought these https://www.screwfix.com/p/sds-plus-sha ... eces/8849v and they do all I want them to.

Thanks Mike, just wondering if it's worth trying to look for a battery version? Would they be 'man' enough for the job?
