Cutting a small notch in uPVC door

Wheety

I need to replace the handles on our back door. I bought a set in Screwfix and everything seems to line up apart from at the top of the baseplate the screwholes have a protruding part. This is cone shaped and it won't fit in the existing hole on the door. I need to make a little notch/semi circle at the top of the existing hole so it will fit. Only need a few mm.

I was thinking a small round file/rasp, which I would need to pick up in B&Q. I have a small hacksaw, a drill, a Dremel (but don't know if any of the attachments would do the job) and a jigsaw. I also have a larger file but don't think it would suit.

Any idea what would be the best way of tackling this?

Would an appropriate size drill bit be able to "saw" through it sideways?

are you moving the hole up or down or just countersinking it a bit . i dont think you can move the holes. the screws go through the lock i think . if its plastic i would get one of those cone shaped grinding cutters you see in co ops that go in a drill and widen the hole

I want to make the holes in the face of door frame itself slightly bigger so the new handles will fit. Everything else lines up as the same as the old handles.

It's just the protrusions on the back of the screw holes on the new handles preventing them from fitting. Only the top holes too

I would use a larger drill bit then

wriggle the drill bit up/down.

Set of needle files will do that job nicely OP, nice and tidy. Useful to have for again

I ended up using my Dremel with something like this (from a Lidl accessory kit) Diamond Wheel Point 2,4 mm Carving/Engraving/Routing | Dremel

Just shaved a small notch and fitted the handles today.

Only had a look at doing it today and I had made it a bigger job in my head really. Surprised how soft the uPVC material was.
