Sds

[matthewgordon]

HELLO

I'm looking to buy a SDS drill. Can someone tell me if they can be used for drilling with core bits e.g. for fan extraction holes? I have seen some SDS drills which state they have a mechanical clutch for overload, is that all I need to look for. Ive only drilled a fan extraction hole once using a sparky drill, it allowed the drill to stay still if the core bit got stuck so it doesn't break your arm/face. This is what I need.

Thanks for any advice

No you really need a core drill. You will just knacker up your sds.

A core drill is the ideal, Onions has really answered best, however an SDS will work for a while but will very likely be loading it more than intended, especially on the 2/3 kg ones, if you have two holes to drill then and SDS will be fine; if you are drilling holes all day then a core drill will be much easier and better.

Go and hire a proper core drill and see how it compares to the SDS you use...... then make up your mind.

For what its worth I bought a Makita Core drill - an excellent bit of kit

They don't make/design drills for coring duties for no reason. Use the right tool for the job. If that means hiring a core drill, then that's what you'll need to do...

Hi,
I used a Dewalt core drill the other day ( borrowed ) and it did a 5 inch hole through 9 inches of solid brick in no time. If you are doing it regular I would definitely use the proper gear,

Regards.

First time I used a Kanga drill it nearly broke my wrist.

my gas fitter mate told me he was working in a corridor behind some industrial site and an Irish chap was using one at face height nearby...while my mate dave was there it jammed (but carried on rotating, well, the drill did) smacking him in the face each time it came round. Broke the blokes jaw.

he carried on holding his jaw apparently, wanted his bonus!


proper core drills "de b0l1okes"

does anyone have any reccommendations on the best core drills?? thinking more reliability, wear, cost? im currently trying to cost up what i need to go self employed by the end of this year and this is just another bit of kit i would consider essential and therefore requiring research

I bought a Makita 8406C Diamond Core Drill three months ago to drill a 5 inch hole through a 2 foot thick stone wall. As Murdoch says, an excellent piece of kit, plenty of power and the torque limiter clutch saves your wrist when the core jams.
I had a sparky core drill before that and the clamp for the front handle broke and I also found that the first time the safety clutch went, it would then slip most of the time when trying to drill 3 and 4 inch holes.
