It's a tool I'd love to use for just that but I can't find a 22mm option, which is what's used on 90% of parts, especially schneider push buttons and pilot lights.
You can get an M22 hole punch for this, but push buttons are actually 22.5mm (PG16) - www.amazon.co.uk/Exact-30506-22-5mm-Screw-Hole-Punch/dp/B00BY2QX6S We'll explore if we can use non-wilwonky punches. It would also be good to cut square holes for 96x96 instruments in panels etc.
I used to work in a small workshop for building different electrical cabinets. We used a hydraulic punch that was a real hazzle to work with but made much cleaner and much more accurate holes. Also you can punch square holes or other shapes for certain uses like a vent. I could see the battery driven punch very useful in that case, hole saws are also awfully messy if you have to drill 20 holes in the bottom of a cabinet. Sharp burrs everywhere and you risk scratching the paint if a single one of those burrs are left on the bench. Now say you got to build 20 of theese and you do all the drilling at once. For the average electrician? Obviously the punch would be overkill, but id get it in notime for the workshop.
Holesaws and a metalworkers deburring tool all day every day for glanding .. punches for panel work, just get individual punches and a socket on the end of a impact driver,. works a treat and its a tool most of us have already got .As you probably know from your recent trip to penn elcom.. most patch bay holes are either 24mm or 31mm so that makes the milwonky defunkt .. Gaz for the win on this one
Armeg Acceler8 or other sheet steel holesaws are going win this race hands down. I didn't understand the fuss until I used them. Faster than standard hole saws and the hole is clean and crisp every time. I haven't used a traditional holesaw to drill anything smaller than a 40mm since I bought them
I think the hole punch makes a neat job. I’ve always used hole saws and a de-burring tool. I think the punch may be better for stainless steel as this is a pain to hole saw through. Can’t see me ever paying for the punch though.
Hello Bob, how are you doing. I hope you are safe and in good health. Looking for a new friend and i saw your pic here. I hope you don't mind thank you.

Nice idea, but you're then carrying two tools to do one job. Or just stick with hole saws? The punch would be perfect for areas that're sensitive to vibration, debris etc.
What we really need is a hand held auto laser cutter, type in the hole size, material type & thickness, line a laser dot up with the centre, pull the trigger and hey presto.. no lubricant, clean hole, less mess and waste.who will be first? lol. Hole punches are nicer finishes, but time consuming. Iv'e cut thousands of holes over the years. Stainless, steel, brass, wood, and the good all rounder seems to be the basic hole saw.😎👍
I use a P&R cutter to make my pilot holes; which I keep in my hole punch case, and I really mainly bought it for the larger punches. but it makes nice clean holes, I don't break pilot bits, and I don't spew as many hot shavings about. for me, the punch kit was well worth the price.
I cannot get it, why did you not include time to predrill a hole for punch down? He was punching using premade holes. Remember in order to punch you still have to drill a hole first.
Depends what you do. Done lots of work on live 600a busbar chambers where you certainly pucker when using a holesaw due to the sparks. The Milwaukee is defo a better tool in that situation, but then hell I'm paying for one. The force logic cable cutter and crimper tho I may look into
The Mandrex Hole saw is a great idea but the arbour is too big. They are sold in my wholesalers but they look far to big and Obscure your view whilst drilling. ANd limit the place you can fit the drill. What your option on that?
You can use the Mandrex adaptors with your existing hole saws -eg convert a Starret to use with the Mandrex arbour. So you can always swap back if you are tight for room.
It's funny watching these guys using cutting fluid. I regularly work on construction sites and I have NEVER, EVER seen anybody is this. Not even once., Now, full disclosure for the most part I didn't either, but I do now.
A cleaner initial hole would be one major difference ('WINNER' for many users) - although the actual application could probably be a decider as well. And keeping a spinning hole saw blade out of the hands of staff can sometimes be an additional safety bonus. A mate has a near crippled hand from a bit of 'brain fade' whilst using a hole saw - it instantly cut the muscle near clean off his hand when he hit the trigger on the cordless drill with a hole saw blade in it = crippled hand (I think many of us are also a bit complacent when it comes to a battery powered tool - for some reason they often seem less dangerous - sort of 'toy like' - other than no risk of electrocution for m a battery powered tool - they can be just as dangerous as a 240V plugged in version - if not more when it comes to other injuries). Safety can sometimes be the 'WINNER'. Yes - we all know that you are not meant to have your hand near a spinning hole saw blades - but we also know that you are not meant to do all sorts of dangerous things (and as at 4:43 am today - if I was standing outside my place - someone doing something they were not meant to be doing - would have turned me into mince meat - instead he just demolished a steel pylon wall and portico pillar - luckily the steel structures stopped the vehicle from ending up in the bedrooms - thankfully nobody was injured) - but still - people do things that end up in injury or death. Have a safe and nice day all - CHEERS from AUSTRALIA.
Gordons Millwonky,seven components to put together to make a hole then take apart to clean out the bits? Gaz three components ,a drill bit a hole saw and a combidrill to make a hole . I have made my choice
Quick connect holesaw systems are great until you try to use them for anything where the arbor needs to also pass through the whole for example drilling through a wall with an extension. This mandrex is a one trick pony as much as the hole punch is. If that's the comparison, I've already got an electrician set of carbide hole cutters that work phenomenally.
Great video guy’s But please send that millwonky back to the Americans and demand refund. Sorry but you just can’t beet the good old hole saw. Gaz you have just proved that 👍❤️⚡️
yeah, I thought that about 30 holesaws ago. but you can only cut 3 or 4 stainless steel cans with a holesaw before it loses its edge. and the manufacturer stopped sending the cans with knockouts.
All that was going though my mind watching you do this was you kids don't know your born. when i started back in the 1960s it was with a Standly hand drill and hole Exnox cutter. Great fun not.
So the punch isn't as accurate? , if it was then surely ALL the punched out slugs would resemble washers and NOT C shaped gobbitts.? Or off-centre washers?
A lot of the punch tool use a slug breaker which cuts the slug in half as you are punching the hole out, makes it a hell of a lot easier to remove the slug especially on the smaller holes.
the punch is designed to split the slug in half so it doesn't wedge in the die. the larger punches will fold the slug. that red stripe on the die is so you can draw a crosshair on your material and then line the die up on the crosshair, even if your pilot bit wanders a bit on your starter hole.
That’s the perfect tool for those who like having there tools nicked or there vans broken into Then having a view day’s off work wile you wait for the insurance company to pay out . Good idea 👍 Great video guy’s as always . Nice tool though despite my negative comment just can’t understand why you would spend a load of money for something that is likely to get nicked . I think someone doesn’t like this comment .
