Drilling Hardened Steel Fast And Slow - IMPOSSIBLE results!

I haven't had many videos posted lately because I've been busy doing things around the house I also did another project and then I got I don't know I got kind of got stalled out it happens when you do this all the time it's not often but occasionally you'll get into a funk and I did and I just wanted to sit around for mono no days on end I didn't do that I did other stuff but I didn't do any videos I didn't do any real projects I did a bunch of stuff out here in the shop to make a big huge mess but really didn't get anything out of it that's part of the process here you do things that looks like it's going to work out fine when you think about them and then when you go to do them and I've got a really good example of that it's a camera stabilizer that I was trying to make and I went through I think five different you know variations on it and none of them worked they went from simple to very complex and they all didn't perform the way I thought they would so I'm back to square one with those anyway I've got to drill bits this is the results of a lot of the comments that I got saying that I was drilling too fast now a lot of my videos are sped up in certain sections so you really can't go by looking at it to say okay that looks too fast because I might have increased the speed of the video you know to squeeze more content into a smaller package I'm not sure about the RPM I never changed this it's always at the same speed and I look at the thing up here and it looks like c2 c2 is 680 rpm so that's not a very fast speed but apparently it's too fast in a lot of people's opinion for drilling holes of carbide a lot of comments about the lubrication areas I should use water one guy even said use beeswax I don't have beeswax I have oil and water I'm not going to go out and especially buy something to do this although I did today I went out this morning and I about two new bits these are identical these are 3/16 of an inch I intend to use them ran out of the package I'm not going to sharpen them to drill two holes into this broken off file most of the comments were for slowing the speed down I did get one comment from a viewer that I know has a lot of practical experience and he said you should actually drill faster and do it dry so I'm going to try fast and dry with one bit and slow and lubricated with the other I'm just going to use while again but I'm going to slow the speed right down as slow as this drill press will go and for this one I'll go as fast as the drill press can go and see how they perform I also got a couple of recommendations or a couple of comments saying that class drills work so I bought one of those this is considerably more expensive than these ones though these ones are like 4 bucks each this is a we can almost twelve bucks so well three times is expensive the idea of the original video was to show using something you might have on hand you know if you're handy around the house or whatever a lot of people have those carbide bits sitting around they might have bottomed with a set of drill bits that you get on special you know at different places and it's just an idea that you could do this with that if you need it to it wasn't about buying this specific brand of drill bit or this specific type of drill bit to drill the hole it was about making do with what you have and that's what I do a lot of on my channels that's what I do a lot of here my workshop so you're getting reality there I slowed down the speed on the drill press to the lowest speed we'll go to and that's 280 rpm for lubrication I'm just going to use 3 and 100 I'm going to spray it on the bit and on the file itself like they say the drill bits haven't been sharpened I took them straight from the package put them in the drill because that was another comment I got well you don't need to sharpen them at all they'll drill it without doing that the other comment about going low speed was apply constant heavy pressure don't let up don't back off because that's what will now dole a bit okay well this is definitely slow it doesn't seem to be cutting at all I'm putting on a lot of force too okay well I'm not impressed it went you know in about I don't know ten thousandths of an inch and I was putting a massive amount of force on it pushing it down and look at the bit and see ya the carbide is actually completely worn flat on the end here I'll get a picture and show it I turned up to speed on a drill press to 3000 rpms that's the fastest this machine will run and we'll see how this works out I think the biggest problem for going fast might be that even though the carb I can withstand the heat the brazing that holds it into the steel shank of the drill bit might fail okay well that one didn't work any better but at least it was more entertaining it looks like the carbide tip itself is embedded into the file so pretty how did you imagine I got the thinking after the first hole maybe possibly the drill bit so I bought which were Ryobi I cut the label off so that you guys wouldn't see it Ryobi doesn't make especially great tools so I'm going to try it with a glass drill the glass rail is Bosh Bosh is known for making high-quality tools although they do make a few duds so get me wrong the other possibility is that the file itself is much harder than the other steel that I drilled before the chisel was hardened and tempered back to a certain degree of hardness it was it couldn't be drilled with a standard drill bit but I could drill through with the Cariboo same with the wrench wrenches are hardened and then tempered back to a degree of hardness to give them the flexibility that they need to be you don't want the chisel shatter the first time you strike it with the hammer you don't want the wrench to break in half you know if you're putting some torque on it so maybe the file is a bit too hard unfortunately I don't have any other drill bits to try this out maybe I should have went with the chisel I did actually look for it I couldn't find it so I saw the file and I said well this is an old file I use this okay and I change the speed back to what I had it before which is my normal drilling speed 680 rpms like I say I don't ever change this because I hate changing it okay I've got the glass drill put in I remember I'm at the lower speed 680 I'm gonna put some well on here because I believe that oil is the best thing oil cools the drilling operation and it also lubricates the cut so that it you know cuts better okay made through it actually punched through the last little bit take it out of the drill press hopefully it's not too hot that's not bad the curve by this in the bed is destroyed but it still did some drilling action you can see actual shavings coming out of there and it did make it through obviously but like I say one hole one bit this is a twelve dollar bit that I just ruined on this one hole if you guys recommend a Cobalt I've had cobalt bits in the past and they didn't seem to be any better than say regular titanium bits but then again it might be a matter of quality like you have here lesser quality better quality one Oh performs the other and they're on the same shelf so you have to I guess take your chances buy it try it and see
