SDS Bits in Hammer Drill

Cerco

Can SDS bits be used in a non-SDS hammer drill.?

I want to drill a 16mm hole for a copper pipe. I don't have a masonary bit long enough to go through the external block wall. I see LIDL have some sds bits on special.
Appreciate any advice.

You can probably grip the ends of an SDS drill in a normal drill but I doubt there are many non SDS drill capable of drilling a 16mm hole through a concrete block wall?

You really should be drilling a much bigger hole and lining it with another pipe.

The problem as I see it is that the shaft of the SDS bit has 4 deep grooves in it whereas a standard chuck has 3 jaws. I can't see those two matching up and working to any degree of reliability.

Just going to try this.....

......... worked OK for me but with a 16mm SDS drill in an average electric drill it looks real stupid and so unwieldy its not going to be a very good solution.

I may however depend on the chuck.

I planned to start with 8mm and go up in steps of 2mm to 16mm.
It is for a 15mm copper pipe to fit an outside tap.
Would a liner be needed for this?
Maybe I need to buy the drill as well then.

Thanks for trying that. It gives me some hope. I will try it out on a garden wall first to see how it works and get a feel for it. Otherwise I might try and rent an sds drill.

Drilling in concrete is just so easy with an SDS drill and the right size bit, so you probably do need to buy or hire and SDS drill.

Irish pipe sizes are imperial so you are probably using 1/2 inch copper (almost same size as 15mm copper but not identical so check what your current pipe work is using the fittings often say what the pipe size is).

1/2 inch or 15 mm will fit inside 3/4 inch plastic pex pipe. So ideally you'll be drilling out a 20mm or bigger hole (if you are bodging it the hole will be a bit bigger than the bit size, with an SDS drill it will be exact so you want so try 22mm).

You don't have to line the hole but its a bit more professional and saves a few other possible issues like damaging the end of the pipe pushing it through.

My wife has just brought home the LIDL "bargains" leaflet. I can recommend the €60 SDS drill, a neigbor has one and has given it a lot of use/abuse.

That's great info. Thanks for all your help.

I used a normal battery 18v hammer drill in the past with an sds bit before I had the sds drill and it worked but very slowly and I went through a couple of batteries. That said an sds drill is always handy to have about the place.

Excellent for diy work. 20v Li-ion, lightweight and plenty power for the normal diyer.

The one I was on about was the 1050W mains powered drill, its an SDS drill but iirc Lidl call it an power chisel or something similar. For the money its a really good SDS drill for DIYer and my nieghbor who uses one a lot is a plumber with much heavier hilti tools but really likes this one that Lidl sell.

+1 to this. I've used my Dad's lidl SDS drill for loads of stuff (including drilling a 20mm hole for an external tap, didn't have a 16mm bit) and it worked a treat.

I've had his drill a few months....will wait until he asks for it back!

I'd go for a rotary hammer drill over a simple drill. You can kango /sds hammer drill / drill (with the sds chuck supplied with it along with some chisel bits for demolition work). 80 quid from screwfix for a decent wattage one.
