Cone cutters

[m4tty]

Hi,

Just wondered how many of you use cone cutter step drill bits rather than a normal starrett hole cutter ?

Thanks

I use a smooth sided cone cutter rather than the stepped one. That way I can make any sized hole. I can see the point of stepped ones if you have a need to be able to size holes with reasonable accuracy.

The other issue in slightly thicker materials you can drill a square edged hole with the stepped bits where it's angled with the other kind. Sort of significant it it's 5mm thick.

I carry all 3 on the van, hole saws, step drills & cone cuts, they all have their place.

I also have some Greenlee hole punches, awesome tools.

I love those hole punches sidewinder, far superior to hole saws. TBH I almost always use hole saws, with the occasional hole punch.

I use hole cutters, cone drills and stepped drills,

as SW says, different uses for each.

do you still get those cutters that you tighten with a spanner? they are great for confined spaces, I no longer have mine,

Were they called Q-Max cutters? Thinking from a long time ago

I use a stepped cone cutter.

Great for drilling accurate holes, e.g 20mm or 25mm for counduit / SWA glands etc.

Especially useful for opening up an existing 20mm knock out up to 25mm or larger.

I use a set of Dewalt ones and cant believe the biggest one only goes up to 30mm so use a round file with that one....
