My A10m started smoldering and stopped working trying to tighten a 50mm screw into a wall plug. Very surprised as I also have a couple of Metabo versions, one of which I use for mixing plaster etc,.. the Mafell has always been looked after though. Just over 2 years old, they will take it back to repair or replace - but only because I filled in the 3 year extension guarantee - good reminder to do it for the Erika that's recently arrived.

Bummer! My sympathies. They're both (Mafell & Metabo) brushed drills, allowing them to burn out the armature when stalled, or even run @ full power with very low RPM. Did the same myself to a pretty expensive Bosch GDR 18 MF (3-function dual speed drill/impact driver) with spade bits.
An expensive lesson to learn, as the tool, at least in drilling mode, didn't have a clutch or even torque adjustment. These days I try to match the tool & gear selected to the load, allowing at least a modicum "headroom" for that all-important fan cooling that's only really effective at speed. Metabo makes a lovely little compact 10.8v PowerImpact (Powermaxx 12 ASE in some markets) which is small, light, compact & at only a mere 100nm. pretty well ideal at most screwing duties short of full-blown lags. I've had one for years now, & find it the only rattler that I trust myself to use with delicate &/or expensive electrical fittings. A pretty gutless & useless construction tool, but a fabulous little screwdriver that has a lot more finesse in its handling & power delivery than most if not all other rattlers I've owned or tried.
Mixing smaller lots of paint or plaster is possibly OK provided the tool's motor can run at or near top speed. The drill should let you know fairly succinctly when it's beginning to feel uncomfortable with any task. I've done my share of cordless tool abuse myself over the years. Another pair of Swiss Bosch GSB 18 VE-2 Li drills getting literally too hot to handle holesawing cableways through steel girders. I'd use them sequentially in turn for the pilot, arbor & saw holes to at least allow some cooling, & tried to always run them at higher speeds in the lowest gear to get some air to the poor tortured armature & brushes.
Electrically commutated brushless drills, relying instead on non-contact electromagnetic field generation, don't suffer anything like the heat related issues of carbon brushed drills. Such heat as is generated is usually more efficiently dissipated from the alloy heatsink finning on the motor's outer casing, as with induction motors.

That’s actually a good thing. There was obviously a weak part on your drill and only a matter of time before it failed prematurely. Could have failed out of warrantee. Now it took a bunch of other parts with it also to an early grave. If the repairs are quality then what you get back is the type of extended warrantee I’d prefer - a gun with a new motor and parts.

Shouldn't happen with such a small screw. Never had a 'decent' tool fail - maybe just been lucky.

Exactly, it was a catastrophic failure prob not much to do with load. You lucked out and get a reincarnated tool with updated parts.
If the screws you use to secure a device are like what we use here (6/32 = approx 3.2mm/.5mm thread pitch) you can almost spin them on as fast with your hands there's so little resistance.

I had the 18v Metabo BS18 Quick burn out on me too last week. I still love the compact size to power ratio on this drill, so I just ordered a new bare tool one for €99

Ive actually killed two of the Metabo 18v hammer drill/drivers myself. Each time it was pretty far out of the scope of the drill so Im not even mad.
First time was 2" hole saws in 5/8 thick steel.... drill actually caught on fire in my hand LOL.
Second time was drilling 1/2" holes in concrete to install Redeye studs. I roasted it, put it down, got out my phone and ordered a Metabo KHA 36-18. Now I have specific drills for specific tasks and im a lot better off.

A10M came back today - new switch... Did it take over 2 months for the repair? Hope the new switch works as planned.

About 6 weeks in total - I've tried the switch, once, and it works. It's sat on the side, I guess I'll start using it again, but I like to really rely on my tools - it's let me down so it's in the corner like a naughty boy!
