Moving along with my latest project, I need to drill a number (40+) of 103mm holes in some PVC flat pipe.
The flat pipe is around 3mm thick, but not much wider than the holes need to be.
I have a 102mm holesaw with sharp teeth, which does a great job - nice and clean, repeatable holes.
My round pipe won't fit in the flat pipe hole - but by a fraction. I really need 103mm hole - and the only holesaws I can see in that size are Tungsten Carbide Grit Holesaw with Diameter 103mm - so not sharp teeth, but carbide grit instead.
I can see 104mm Rotabroach - but I don't have a mag drill, other than that, it appears to be 105mm.
Does anyone have experience of cutting PVC with a carbide grit tool? They're obviously intended for tiles, brick or similar, so I worry they might get clogged up with something that could melt - like PVC.
Or can I 'set' or splay the teeth on a 102mm tool somehow?
Thanks
Depending on the size of the teeth, you could use a saw set tool. They're cheap enough (secondhand) on eBay but I could send you one if that helps.
Personally, I'd just stick a strip of coarse emery on the holesaw body.
