Drill big holes in 1" thick steel - Fastest way? - Iron - Metal - Aluminum - Large Drill Press

hey what's up guys welcome back to the shop my name is Gary and on this video we are going to be taking a look at how to drill large holes in thick steel we've got some 1 inch thick by 4 inches wide flat stock that we've cut up into 2 small pieces and we're using that as as part of another project as you can see here and if you're watching this sometime in the future I'll link a video to the to the project that this actually is being built for but focus of this video is kind of walk you through three different methods to get a large hole punch through thick steel so we're going to take a look at an annular cutter we're going to take a look at a one and a half inch or one and five-eighths inch twist drill and then we're going to look take a look at using a regular hole saw and we're going to time each one of them and try to keep it as fair as possible and you'll see the length of time the process used to that we're going to do this so let's take a look and get started alright so first up here we're going to use this annular cutter and this is the package that it came in I got this off eBay I've had it for a couple years it's been used a few times I'd say maybe half dozen times but it's still really sharp and in good shape and these things last a long long time so I think it could be considered to be you know fresh tool or sharpen tool whatever but so we'll go ahead and get this chucked up and start the timer and come back at the end and kind of give you a summary of what worked good what doesn't work good and go from there [Applause] [Applause] [Applause] all right you saw we had no problem at all pushing that through in one pass just plunged it right through there the one thing you'll notice is I use plenty of lubrication you know just keep dabbing the oil in there don't want to run anything dry but the one of the downside is is this nasty swarf it comes off of it and sometimes you have to stop and clean it out you know because it just gets all tangled around it a lot of times it'll it'll kind of self evacuate but and then it leaves this slug at the end here so you know you're not turning the whole end completely into chips you're producing this slug that yeah you saw the timer there a minute and 52 seconds to get that through there which is pretty good and you know really I could have plunged it a little faster you know I was trying to be gentle on the tool but also you know be productive and get it through there so all right we'll take a look at the next tool [Applause] [Applause] [Applause] [Applause] [Applause] all right well you saw we had no problem using this method in fact I for some reason I kind of like using this method some people will say well you don't need to run that many different drills through it you might get away with just running the 3/4 or maybe start with a half inch you know plunge a half inch hole through and then step up to the one and a half I don't know I just like I feel like it's easier on your tooling to step up more progressively you saw there that that took the longest amount of time at seven minute and one second the chips that it produces are really easy to work with they they pop out of there you can vacuum them up easy with a shop vac compared to the swarf that this thing leaves you know it just is a lot easier to clean up so the downside is making all the changes you know between each of the tooling having to re-check everything up that's what it's costing you the extra time here so all right we'll step to the next one [Applause] all right well as you saw we were able to get that push through there and I think that you know you definitely need to take lotta cuts with this meaning you can't push as hard with that you could with the twisted ruler annular cutter and I start with I was I was pushing a little bit too hard on it and you can see the slug that it produced there you can see that the timing SiC the six minutes roughly took to get it through a little bit faster than the twist drill method but not near as fast as annular cutter and but the main issue with this is that there's no chip evacuation and you can see this little fine chip that it produces and what it ends up doing is just sort of you know regrinding its own chips in there so you have to kind of pull out blow it out with the air especially as you get down in there deeper you see the annular cutter has the flutes on it and that allows you know for that swarf to evacuate out of there and makes it much more effective and you can also see on the teeth just the thickness of it but it worked you know if you're doing this at home I would I would say that the main issue that you run into trying to put thick metal big holes through thick metal at home with a hole saw is just to be able to turn your drill slow enough you know you need 200 rpm for something like that most of your conventional drill presses that you buy Home Depot Lowe's those are made for woodworking and probably have a minimum of 800 rpm you know and I think mr. Pete had a video on doing a VFD conversion on a regular drill press you can lower the RPMs but my experience with VFDs on machines is that when you try to use it to get a really low rpm out of it you lose all the torque with it and what you really need with this is the torque so also Chucky's through 2009 did a video that he got a Powermatic drill press from the texas gun guy and did a restoration on it and it had variable speed all the way down to super low rpms and you know work extremely well so I think picking up something like that for a thousand bucks or something in that range you know was a good option over spending four or five thousand for a mill so yeah so that's it you saw the three methods there just wanted to share this video with you guys [Music] [Music]
