How To Drill HUGE Holes In 1/4" Steel Plate
Вставка

- PLUS a bonus hack to help you NEVER AGAIN break the 1/4" pilot drill bit in your hole saw set!
Here you'll learn how to use a large hole saw & a drill press to make two things:
1. a HOLE in the steel plate, the size of the outside diameter of the hole saw, and
2. a PLUG or disc of steel, the size of the inside diameter of the hole saw.
Today I'm after the plug that's left when I drill a hole, but the same exact process applies, regardless of which part you're after. - Навчання та стиль
Nice teaching. Great help to me, supplementing what my Dad didn't get to teach me.
Awesome! Glad it helped :)
Nice video. Cool trick with the 1/4" rod in the hole saw. Thanks for sharing this.
Great hack bro!!
1/4" rod idea is priceless
Thanks!
Well explained sir; congrats!!👍🏻👍🏻
Mario Gonzalez thanks! Glad it helped, and I really appreciate your feedback :)
really informative thank you
Thanks for this presentation. I do appreciate your clear pronunciation. It shows respect to the listener. Regarding the pilot drill, I do not experience them braking off. Maybe my chuck and/or spindle is better aligned.
thanks. very helpful
Good one, I'm messing around enlarging 2 1/2" holes to 3" in 1/4" aluminum plate. I like your idea of substituting a steel rod in place of the pilot bit. Aluminum grabs worse than steel ... you solved my problem .... Thanks.
Awesome, glad it helped! Thanks for the comment 👍
it will help tremendously if you drill a relief hole just inside the kerf of the hole saw to allow shavings to evacuate the cut. Place the hole on the side that will be the waste side when complete. Minimum 3/8" diameter.
I’ve never heard of that method, but it makes a lot of sense-I’ll have to try it! Thanks for sharing!
I find it easier to start holesaw then use drill bit about the same size as kerf in multiple locations. It makes the chips smaller .
It's also a lot easier and faster to drill multiple small holes.
Works particularly well in aluminium
Use a shop-vac to keep the metal cool and suck up the bits. I find this works better than oil, although you can use both, too.
Thanks.
Hi can you make vidoe on drilling holes on a circular saw blade please
Great vid,I need to cut a 2" hole horizontally through 1/4 I beam .Think I'll suspend drill with cable or just find someone with plasma cutter
Thanks!
I'd suggest checking out if you can locally rent a Mag Drill. If you're not familiar, it's basically a compact drill press that magnetizes to your I-beam with a powerful electromagnetic baseplate.
How many rpms is your lowest speed setting? Do you experience any issues with burning up your hole saws at that speed?
hey, great vid! wehre can I get one of these?
A hole saw? Either home improvement stores, or Amazon etc.
You can normally buy 1/4" steel rod stock at steel supply places, but home improvement stores like Home Depot, Lowe's, or Ace Hardware should also have some.
In general, if you have a steel recycler that sells by the pound in your area, or a steel supplier that sells remnants or cutoffs, that's often a cheap way to buy steel.
You can also get some online: www.google.com/search?client=safari&hl=en-us&sxsrf=ALeKk01URWlYxv4Oq4a0tH72xXejAAVdMg%3A1606578658645&ei=4nHCX-_pJoms0PEP2u6z0Ao&q=1%2F4%22+rod+stock&oq=1%2F4%22+rod+stock&gs_lcp=ChNtb2JpbGUtZ3dzLXdpei1zZXJwEAMyBggAEAgQHjIGCAAQCBAeMgYIABAIEB4yBggAEAgQHjIFCAAQzQIyBQgAEM0CMgUIABDNAjoECAAQRzoKCCMQsAIQJxCdAjoECAAQDToGCAAQBxAeOgQIABBDOggIABCxAxCRAjoFCAAQkQI6BQgAELEDOggIABCxAxCDAToHCAAQFBCHAjoICAAQCBAHEB5QrWxYka8BYJq8AWgAcAF4AIABvgKIAeULkgEHOC4zLjEuMZgBAKABAcgBCMABAQ&sclient=mobile-gws-wiz-serp
Huh I’ve never broken a pilot bit using the larger or smaller holesaw mandrel. No drill press either just a compact brushless drill
Need to add lubricant as drilling, will keep drill cooler also taking too long to drill part .
How do you drill a disc with no pilot holes? I need to drill (or find some to buy somewhere) fifty 1-1/2" x 1/8" thick metal blank discs with no holes in the center. I can find plenty of thinner ones on ebay, but nothing thicker than 1/16"
Hi what make and model hole saw do you recommend for 1/4 inch steel
I really like the ones Milwaukee makes. Can’t recommend a specific model because I have an old set that I just keep using and using.
Just read the packaging and their recommended materials & thicknesses. I can’t stress enough the importance of using some kind of lubricant oil to cool the hole saw and metal as you drill. You can use official cutting fluid, though my favorite is what I ALWAYS have on hand-Power Lube. Works great.
In a pinch once, I used air tool oil because that was all I had with me and I was getting my family out of an emergency stranded situation on the side of the road in a snow storm, at night, on Christmas Eve. Had to bore out the inner hole on a spare tire rim that was too small for the trailer axle hub it was supposed to fit on. It worked great, and to my knowledge (it was years ago) I’m still using that hole saw!
(That’s probably the event that caused me to always keep a can of Power Lube in the back of the car-besides the ever-present need to unstick stuck things, and keep them from getting stuck again 😉).
I had no idea you could use these on metal. I have a couple and thought they were for wood only.
Some are definitely better and more suited for metal than others are, so if you have cheap ones they will probably wear out very quickly using them on metal. But using some kind of cutting oil like I showed in the video will help it last as long as possible.
@@TomWylie Thanks. I think the wood already wore them out after one use. Probably Chinese metal.
...Oh don't even get me started on China right now. Just lost my job of 26 years because of their virus thank you.
ArcanePath360 oh man, really sorry to hear that.
@@TomWylie It's okay. Bit of a shock at first, but the more I think about it, perhaps it's time I moved on. There's certainly elements I won't miss.
you have to use bi-metal or carbide hole saw to cut metal the regular ones are for wood or plastic
Rather use compressed air and a gun , it cools the saw and removes filings , I drill 25 mm thick plate
Looks like running too fast.
If you do a lot of drilling. Get a mag drill. Your welcome
Yes mag drills are awesome! I would love to get one someday.
what if the surface is not metal?
Should never wear gloves when operating drill press. ..
Yes, and one should *never* use a 6 foot ladder to go more than 4 feet off the ground.
That's technically the rule, but the few times my gloves have been caught in any kind of drill (usually just hand-held drills) are FAR outnumbered by the countless times my fingers have actually been saved by the fact that I was wearing these gloves.
Would I wear bulky leather or canvas work gloves while operating a drill press? Absolutely not!
But if I get close enough to the bit for these tight-fitting gloves to catch, that means I was just plain too close to it period and was already asking for trouble.
TomWylie you are correct. .i wrapped my hand around backwards wearing gloves. .loose ones...
If you're chuck has runout you need to fix it. And it's still to fast change gear if you are going to teach other's how to do this no sense teaching the wrong way just because you can. Life hack just cause its on you tube don't make it the Right way. The shade tree way is not the way to do it unless you don't mind losing a finger or two.
where might I find the best practice way to do this?
@@partyshorts this way is perfectly fine. Just take your time and be safe.
