SDS drills

[Timothy Murphy]

(1) What exactly is an SDS drill?

(2) Is a cheap (eg Aldi) SDS drill adequate?

(3) Could an SDS drill make a small hole (for a screw with rawplug) in granite?

[Lurch]

When you say exactly do you want technical information of standard shaft sizes and gearbox assembly? The SDS is the design of the chuck and drilling method used.

Adequate for what? If you want to use it as a doorstop it's perfectly adequate.

Certainly could.

I take it you didn't bother looking in the archives then? Have a look at

SDS related discussions. ..

The drill bit locks into a bayonet type fitting rather being clamped in the traditional manner of a drill with a chuck. This is far better when using a hammer action to drill brick / concrete

It's adequate for most household drilling jobs.

Yes, best to start with a 6mm sds drill bit first (tungsten tipped for drilling brick / concrete) then use your final size of drill (oh if it's a 2 speed drill use 1st speed for granite)

You could at least include a useful link:

What sort of granite: granite as in worktop or granite as in kerb. I have a strong suspicion that an SDS drill applied to the former would result in an ex-worktop!

[Timothy Murphy]

It is a granite wall in an old house.

[T] If you drilled a bigger hole in the granite wall and found a uranium (is it?) rod to slide in there you might get some free heat / electricity (isn't real granite radioactive?) ;-)

All the best .. T i m

p.s. An SDS drill should make a hole in anything that you could damage with a hammer and punch.

[Tony Bryer]

Definitely a case for SDS

The large granite plutons as found in the south west and other places have a lot of radon gas coming up through them. It's the radon that is radioactive.
