Corded tools are so handy sometimesNot sure if this what I fixed or broke today. Over the weekend as part of the continuing sorting out of the kitchen I took the cooker hood off to find the pipe work not connected and instead of extracting outside it was a big greasy mess inside. The pipe work had little chance of staying together as it looked like a short piece of drain pipe bashed out of shape into the wall but too short to reach both sides with a flexible hose twice the width that must have just been wedged in.
Decided I’d sort it properly so bought an extractor kit and a core drill bit. Core drill wasn’t wide enough so had to return it and order one off Amazon. That arrived today but went to fit it to the SDS adapter and it wouldn’t fit because the adapter they sold me with the original core drill was M22 instead of 1/2 bsp so another wasted trip back to Toolstation. Finally got all the right size bits and adapter so let’s make the hole bigger. Not so easy as I can’t use a pilot drill to stop the core bit jumping around so I had to cut a hole the size of the core bit in a piece of ply and attach it to the wall to act as a guide.
Finally I can start drilling only to have more problems. First time using a Forge battery on the big Milwaukee CHPX drill and it cuts out instantly when fully pressing the trigger. Tried a 9ah battery and it would work if I slowly depressed the trigger but it still ate through the battery before it got through the inner bricks. Swapped out for a 5ah and I started to make progress until it stopped dead with flashing battery lights (over heated). Slapped another 5ah battery on but it cutting out, the drill was hot now. Only thing making progress now was the red mist. Stuck the battery on charge that had previously over heated but only got the flashing red light so removed it and let it cool down some more. I decided to get the compressor on and cool the battery with the air before putting it on the charger again and thus time it started to charge up. I thought I’d give the drill a blow out too even though it looked clean and usually blow it out after dirty jobs but it did the trick and with previously removed battery the trigger would allow a full press without cutting out. Back to cutting a bigger hole and it continued to work until I overheated the battery again but had managed to cut through to the outer bricks. Another fresh battery on and finished the cut, slowly but with issue and didn’t blow the brick work out.
Extraction ducting fitted perfectly and expanding foam filled the minimal gaps. After a complete farce of starting the job and tool problems after getting the right bits it’s a job well done, even if I say so myself.

Interesting. I've got the same drill I think and it was quite happy doing 6h non stop hacking render off with a 12Ah and a few 5Ah batteries in 30°C ambient. Not drilling but just on the hammer mode.big Milwaukee CHPX drill and it cuts out instantly when fully pressing the trigger.

I only ever use corded for the bigger stuff like soil pipes thro a double skin....even then it's sometimes a struggle if the bricks have been fired with added kryptonite!!!For the few times I've had to Core drill I've used my corded SDS
I guess thats why it's good to have a mix sometimes. For the few times I've had to Core drill I've used my corded SDS. It's nothing special but it works. For other times I've got an 18v SDS makita which will do hammer only which is good for bigger drilled holes up ladders and removing plaster etc and then I've got a 12V Makita Drill which pushes well above its weight. perfect for lots of small holes and light enough to hang of a work belt.
