The icon is a little different to what I've seen on others and I don't know how to tell otherwise. I have a job that involves drilling through a breeze block wall about 20cm and I don't want the expense of buying an SDS if I can help it.

This drill was given to me a long time ago, hence not knowing what I have here.

Thanks!

It is but for that depth you'd be better off using a rotary hammer drill. Maybe you could just rent one?

Edit: You could give it a try. Just make sure to use a masonry bit.

For your project you need an actual hammer drill. This might work to plow an anchor into some mortar between bricks but I would get the right tool.

Rent it or check to see if you have a local tool library.

But buy a new bit. Fresh bit makes a huge difference.

I’ve attempted a similar job with one of those. Do yourself a favor and get the better tool.

I think that is a hammer drill setting. Looks like a cordless dewalt. It will get into breeze blocks easily but 20 cm deep may be a challenge. You need SDS pneumatic for proper concrete. Not for breeze blocks or bricks. Depends on diameter too. If you need a hole for a dryer vent, you need a drill with decent power. Wall plug in breeze blocks, any drill will do

I need a 20mm hole to feed a CCTV cable through that has an RJ45 connector so it's a lot fatter than just a cable. I'd try work up in hole size until I get the right size. But maybe a cheap SDS is the right way to go.

Working up in size doesn't work all that well in my experience for masonry bits. They don't cut material, they pulverize it. Trying to run a larger bit through an existing hole is prone to jamming.

Can you get more connectors and a crimper and put on a new connector after running the cable through a smaller hole? That's better for sealing anyway.

Thanks. It's a weird cable with 3 ends: RJ45, power barrel connector and reset switch. The RJ45 is the biggest, but the others aren't too much smaller. I thought about having a junction box on the outside, but I'd like to keep it clean and tidy without.

I don't think it will do the trick. There's usually a hammer symbol if it does.

[–] [email protected] 1 points 1 year ago (2 children)

Is that not what the top symbol is? I've seen it looking differently on others

[–] [email protected] 3 points 1 year ago

Yes it is - bit of a tool nerd here but I think that is a JCB Combi Drill. That is JCBs slightly unusual “hammer mode”, and should be no problem to drill 20cm into breeze block with a decent bit. There are a vast array of what people call “breeze blocks” from 3.6n Aircrete (one step up from that green stuff florists use) to full concrete blocks with drill blunting pieces of ballast. This drill with a decent drill bit will do all of the above, but it might take a while and need a better drill bit for the harder options.

It must be the symbol for the hammer function, not much else it can be.

If you find the brand name you should be able to find the model and manual.

Also depending on diameter of the hole SDS drills are better, but if it's only one hole just try and see.

If it starts getting to hot or struggling you know you need a bigger drill 😂

[–] [email protected] 2 points 1 year ago (1 children)

Probably a bolt, not a hammer. Every drill hammer I've used has the hammer symbol, the drill symbol and then a combination of both. This lacks the combination, so it's probably not what OP is looking for.

Fair point, it could be an impact driver.
