Drilling Hardened Steel With Masonry Bits

drill hardened steel with a masonry bit in this video I am actually going to show you how to sharpen a masonry bit so it can cut hardened steel and I'm gonna demonstrate actually drilling hardened steel the drill bit I'm sharpening today is going to be a 3/16 which is 0.875 the reason why is because I need to drill out a quarter inch high-speed tap which is a number seven which is a 202 if you're just learning hand grinding techniques it's better to start off with the 3/8 to 1/2 inch because it's easier to see and easier to handle before we get started please take a moment to like and subscribe it's free and it'll help me out okay let's get started right now okay this is the wheel I use it's one that I got on Facebook it's a high-end diamond wheel I paid $5.00 for it and the reason why I'm using that one is because I really really like it now if I didn't have that wheel and I really wanted to do this there's a bunch of different options here this one goes on a grinder you can turn around this is not recommended by me in any way shape or form but you could turn around and put your grinder your put your hand grinder in a vise and then actually grind and hold onto these these guys here there's a few people that turn around and use this style on their table saw and you say well these are expensive I doubt I paid five bucks for this thing now this one here is a preferred style over this one because it's a segmented cut so this one here will actually be on the sharpen tool and better and this guy here I paid three bucks for it and it is a very good quality nice time is laid inside though ideally this is the best when you have one of these but these will work almost as well okay on the far left is the actual drill bit that I sharpened in the middle is a drill bit sharpened and a non sharpened drill bit and on the right hand side is a spade bit what I am trying to do is mimic or copy the geometry that is on the Spade bit and put it onto a 3/16 masonry bit with that profile they will cut like a knife through butter and hardened steel and I attempted is try and make this masonry bit into a bit of a spade bit if you see here this thing will not cut so let's see we can do see if I can get it to cut so the first thing I'm going to do is sharpen it like a regular drill and then I'm gonna have to take out all of this extra stuff at the front what I'll do is I'll just grind this away with the regular bit because that's just steel and well I'll grind this side and then I'll going that side the front face off and he's inside of the wheel over here I know if you can see it or not all I did was growing the front of this side off now I'm gonna try and put on this side here and undercut and then flip it over and do an undercut here and then I'm gonna put clearance on the sides as well so let's see how that works [Music] [Applause] [Music] [Laughter] [Music] [Music] [Applause] [Music] probably should have done this with a half inch bit instead of a 3/8 or a 3/16 but if you take a look you can see how it's an undercut there and if you look on this side there's an undercut there so basically the edge profiles the same as a regular drill bit and this will cut hardened steel well you can see how small this is just by looking at the size of my fingernail this is quite a small bit but this guy should cut all the geometries there okay I'm gonna drill a hole through this craftsman wrench okay I bought it at the restore for $0.50 okay just so I could drill a hole through it I don't want anybody emailing me complaining about how I'm destroying tools etc or disrespectful the tools it's the total opposite what I'm trying to do is prove my tool sharpening here for this guy this is a masonry bit I just sharpened it up you'll see in the video no trick photography or anything like that this face is not mounted the table is not locked the reason why I'm doing this is to show the use of this drill and a non rigid setup I will be kind and throw some topping fluid on here for some cutting oil no it is topping fluid [Music] see the chips coming off look at that there is some flex in the wrench [Music] we'll see getting more on the base than I am in the drill dole I normally wouldn't use oil because I can resharpen but I want to drill through a couple other things [Music] and when I'm done I'm gonna pull out the drill without cutting the video at all it's a good 3/8 thick probably [Music] starting to coat the other side hey now I don't want to touch the bit cuz it's gonna be warm hopefully you guys can still see that still sharp that'll still cut house a little bit scratching on the side and to prove see the hole through there well hopefully you picked up a tad bit of knowledge and you enjoyed the video if you got any thoughts or feelings
