I have a decent SDS drill and a makita battery drill. But no mains drill since a
killed a cheapy a few years ago.
My makita does not have the oomph to turn the 50mm holesaw once the whole saw
(d'ya see that ?) is in the timber when drilling the bottom of the socket for
the newel post spigot, so I need a mains drill to finish the job.
Or a chuck adapter for the SDS (can do rotation only).
Any recommendations (sub 100 quid) ?
However, my SDS (and I think this is usual) has a relatively low top
speed (as do many battery drills). Nowhere near that of a good,
Also, many SDS machines are far too long (overall, and especially with
SDS-chuck adaptor) to use conveniently in any but easy-access locations.
Until I positively need one, I will not buy a new mains drill. But that
might be short-sighted of me.
My SDS is the "next size up" so is a bit heavy for medium weight stuff.
I have a 750 watt Ryobi which doesn't get much use but is invaluable
when I do need it.
I think it was under £40 from Screwfix but doesn't seem to be in their
current lineup but you should find something adequate for well under a
ton. Even the Titan gets decent reviews (not that Screwfix is my first
choice source any more).

Drilling large holes in wood - like say when fitting a mortice lock to a
new door. Cordless goes flat too quickly - and SDS with normal chuck added
simply larger less wieldy and slower than a mains drill.

I agree the chuck adaptors on an SDS are not ideal for many jobs, but I
have no difficulty using a decent 18V cordless for large holes in
wood... I did the 2" hole into newel post bases using an expansive bit
in one without any difficulty, and a 5" holesaw through 3/4" ply. I
would also expect to be able to do several mortice locks on a single

Well I got an SDS chuck adapter and it was fine since the hole saw already had a
path to follow so the wobbliness did not matter. But otherwise it would not be
the most precise method of drilling.
The friction of the holesaw once it was all the way in the timber and relatively
slow speed of the makita battery drill was the issue. Loads of power with the
SDS and adapter of course.
I had thought of using the spade type bits (expansive or a 50mm one if
available) but assumed the hole would be too messy. Usually recommended is a
forstner bit (but they go off track easily) or a holesaw.
By the way, I did the first part of the hole using a pillar drill with the head
turned backwards to get it vertical - until I ran out of travel and the belt
started slipping !
The expansive bits seem to cut quite clean... To lower the torque
requirement, I find its better to drill a 5mm pilot hole dead centre
first, this stops the worm drive from pulling the bit into the work so
hard. Then you can control the feed rate better.

I'd go for a chuck adaptor. Higher speeds just tend to overheat larger
bits and at 25mm radius, it's angular speed will be pretty high on a
/slow/ SDS. The SDS torque will let you lean on it more so it'll have
more bite per tooth rather than bogging down.

The holesaw in chuck adapter worked well and full speed was much too fast,
burning the wood etc. When I realised this and ran it slower, it had plenty of
torque and cut very well.
I think I will do without a "standard" mains drill.
My first drill was a nice green mains Bosch which has fallen out of
favour besides SDS and a cordless drill & impact driver set. The few
times it does get wheeled out is to deal with 11-13mm drill bits as the
cordless chuck, as per many, only goes up to 10mm. And that's only when
the work can't be crammed into the pillar drill!
Fact is, having more than one drill is a big time saver. Countersink,
pilot hole etc. It's not so much the time it takes to change the bits
but the time it takes to find them again after you've put them down
Indeed multiple drills are very useful. I have three cordless of my own
(big Bosch and two small Makita ones - impact and ordinary). Plus SDS.
And access to a pair of Makita cordless.
Still have no great desire for a mains non-SDS drill.
For repetitive tasks, it *is* the time taken to change back and forth
that's the pita.
Which is why I decided to hoard Makita cordless. :)
Oh boy; that's paid for itself already, the amount of time I've saved
having one with a drill, screwdriver bit, and square-section drive all
