Gentlemen,

Anyone know what's currently a good deal for one of these higher power
drills? I want one which does the usual hammer stuff plus chisel and
core drilling plus also being able to drive in M16 thunderbolts into
concrete.
I thought one of these would do the trick as it seems to have
reasonable power, but will have to be returned under warranty as the
speed controller has gone haywire:
https://www.screwfix.com/p/erbauer-erh750-3-4kg-electric-sds-plus-drill-220-240v/232fv#BVQAWidgetID

So.... anything more suited out there?

cheers,

CD

Depends on what you mean by higher power... 700 - 800W is about par for
the course for a 2kg class machine.

The larger 5kg class machines will give you more joules per hammer blow,
and better SDS drill performance in hard materials. Although more
expensive and more tiring to use for day to day work.

SDS Max machines are serious brutes - but again (much) more hammer and
drilling capability. Not necessarily much extra core capability though.
(Max tooling is also quite a bit more expensive - but you can get larger
dill bits)

Most SDS machines will claim to do 80mm diamond cores. In reality you
can do larger if you take it very carefully and get the hole very
straight. (I have done 107mm cores with by SDS - but you are right on
the limit of the clutch letting go). If you need larger cores regularly,
then get a core drill[1]

[1] But not the sparky like mine, which is pretty poor! (clutch lets go
too easily on that)

That's almost Makita money:

My old 2450 has taken years of use and abuse, and still works well
(although I did have to replace the armature once!)

Thanks, John, I'll check it out.

You've also looked at the heavy Titan SDS+ drills at Screwfix?

I'm curious why you would tighten M16 bolts with a drill rather than an
impact driver?

I bought the small DeWalt from TLC many moons ago - when it was IIRC the
only reasonably light SDS on the market. Didn't want a heavy one for wall
chasing, etc. Still works just fine. But only gets used where I need an
SDS.

No, I wanted a make I was reasonably familiar with and AFAIK, the
Titan stuff is Screwfix's own brand and might be made of junk for all
I know. BnQ has the same scheme with their MacAllister range. Having
said that, I've had a Mac 4" grinder/cutter for many years that's
taken much abuse but is still working as well as ever it did.

>I'm curious why you would tighten M16 bolts with a drill rather than an

Yeah, I'm really not a metric person. I meant something quite a bit
smaller than M16.
You're right about the impact driver, though! I'd forgot that:

A) it would be for more suitable and
B) I've got a HD pneumatic one already!

The 6Kg Titan drills are great workhorses. Not at all refined, but very
powerful. In a completely different league from the Erbauer one.

I recently bought a Titan SDS+ when my ELU packed up after a lifetime of
use and abuse. I was looking forward to using some Auger drills I had
acquired which had SDS+ shanks only to find the bugger did not have
reverse. I only bought the Titan as in my twilight years I have less need
for that sort of power being able to drill the brick and breeze block walls
easily with my battery DeWalt.

True. It doesn't. It's very good at making holes in things, though.

In one side and out the other!

When you want a easy way of demolishing something then they are ok, but
for much work, finesse is a bit more important IMHO.

I can stick a chisel on my SDS, and lightly cut through the plaster skim
following a line round a backbox cutout. Then sink the edges cleanly to
depth, and finally hog out the waste, planing down the back to a flat
(enough) surface to mount a box in. Some machines are a bit too much
"all or nothing" to do that kind of stuff neatly.

Extraordinary! So... the auger in question is still deeply embedded in
a tree trunk somewhere awaiting liberation?

I decided to order the one you suggested, John. I kind of lost faith
with Erbauer after that issue with the speed controller. It's supposed
to ramp up the speed smoothly and 9 times out of 10 it did, but every
now and again it would go from zero to flat-out in a split second,
jerking like billy-o in the process with the sudden torque! Scary. And
dangerous!

It's a dichotomy. To buy a powerful SDS that is also heavy but can make
light work of breaking up concrete and drilling large holes. Or one light
enough not to tire out your arms when chasing walls. Or just buy both.

I have three machines that kind of fit the bill - my Makita 2450 2kg
class, a Wicks branded (OEMed by Sparky) Max SDS which I bought for
peanuts, and a 15kg chinesium concrete breaker. Of those the Makita is
used by far the most (>90% of jobs), the 15kG breaker rarely, and the
SDS Max hardly ever (I think I have used it 3 times in the last 15
years, and would have used it a fourth if I had a 30mm SDS max drill bit
for it).

So the smaller lighter SDS wins for most jobs. If I added anything else
it would be a 18V (or probably 36V) Makita SDS.
