Core drill ?

[markus2025]

Hi guy hope this is right place to ask

I need to get a 100mm hole through my brick wall for a vent duct .

Ive read about only using a core drill for doing core holes however alot of people use a sds with hammer off if it has clutch

I have a 110v hilti te55

Can anyone suggest if that would be any good for doing a core hole

Many thanks

It depends on how hard the material is that you are trying to drill through. I have sucessfully drilled 100+ mm holes with my SDS drill but also had to hire a heavy duty drill for some jobs.

It will depend on how tough your wall is. Hilti are the best so it stands a chance.

If it has a non hammer rotary setting and is clutched and is running through a standard domestic brick wall then yes it should do the job with a dry 100mm tube. Just let the tool/tube do the job at it's own time, don't push too hard.

I have only drilled a few 4" holes. I used a cheapo Titan 6kg SDS drill (with hammer action turned off).

It did the job. The drill does have a clutch but I drilled slowly.

I have used 2kg SDS drills to dill smaller cores.

I drill large holes so infrequently that I have never been able to justify the cost of a dedicated core drill.

and is clutched

This is the important bit, my SDS has no clutch, not superpower full so it would stall rather than turn me around with the drill, but not ideal, you really need a drill with a clutch.

Drilled many core holes 105mm and smaller with Makita SDS drill, with clutch

Ohhh, on reflection, perhaps my old Titan SDS didn't a clutch and was simply stalling. Either way it offered a degree of protection.

That said, it did snag and twist once when I was trying to drill out a gate fitting from a brick wall. It hurt.

Thanks for the correction.

If a hole is being cored and the tube snags for whatever reason on a gun with no clutch, then it can break a wrist.

Really? - I've never ever given this a thought.
Don't even know if my SDS drill has a clutch, how do I tell?

Of course it's worst case scenario but it can cause light sprains to bad sprains with swelling and bruising right up to fractures, it is a known consequence of a rotary gun without a clutch or one where the clutch doesn't work and it jams, huge amount of torque in these guns
