Can't remember the size the Q-Max needs, but it's less than 10mm and doesn't need its own pilot. If accurate alignment is required I reckon a centre punch would do the job.
20mm holesaw Vs 20mm punch
- Thread starter RF Lighting
- Start date
I always use an 18 or 19mm holesaw if I'm drilling for a bush and coupler..
the internal thread is 18mm so it makes a much tighter fit for the coulpler and bush..
I have a "set" of those punches ( not really a set, but a bunch of individual ones I bought.. ) .. 20, 25, 32, 38, 40 and 50mm..
the 50mm came in very usefull at the last place i worked for putting 315A isolator handles through the front doors of 400 x 500 enclosures..
if you get a right angled chuck for your drill and a small step cutter ( 4-12mm ) then you can get into some tight spots above some CU's to put new holes in where you wouldn't reach with a holesaw..

Very rarely TBH. I generally use it on CUs and trunking etc. It doesn't seem to show any signs of wear yet, so I'm not sure really how it would effect it's life.
It's a Nikon L100
Well, I managed to drill a hole!
And the winner is.....
See the post below by Lectrician
Is this the one you have RF?
What size pilot is yours?
You drill a hole to allow the bolt to pass through.
You then assemble the parts as shown, with the punch one side of your panel, and the die the other side.
Use 2 spanners to wind them together, until you cut through the panel.
You will need to remove the scrap piece from the die, each time.
It should be a piece of cake to drill a 20mm hole in a bit of thin metal like a piece of uni strut
i regularly use hole cutters for holes up to 80mm in steel often 6mm thick
stainless is a pain
ally is also a pain but a bit of wd40 makes a massive difference!
you should easily be able to drill a 20mm hole in a bit of 10mm steel!
hole punches are great but i would prefer to use my hydraulic one, ive got a couple of handy punches for that things like 72x72 square etc
I always use starret hole saws as i find the cheap ones are poo
the new hole saws designed for use with battery drills are very sweet and very good for thin steel too
the other tool which is very very good on thin steel is a stepped cone cutter.

It is.
And it gives you a hole with the edges as neat as those on a slice of cake.
It's not about difficulty, it's about quality of end result.
I've never used one - how easy are they to control?
As in stop when you've got to the size you need....

The flute depth for each dia is about 4 or 5 m/m, when you break through each diameter, you will feel a small jolt as you engage the next flute, obviously this is when you stop.
They deburr the top of the hole, as you touch the next flute, the underside is as bad as a hole saw.
I've never used a step drill, but cone cutters are basically the same without the steps, and they're very easy, just put a suitably sized washer on them. Not the cleanest cut ever, but they're quick and only require a tiny pilot.
