Micro Drilling -- Stop Breaking Small Drills !!

hey guys joepie here advanced innovations welcome back to the shop thanks for coming back I'm gonna show you a technique today that I learned a very long time ago and it was an aha moment for me very much like when you're working on a car and you struggle through something for hours trying to overcome a certain obstacle and then you find out that they make a tool for that that would have probably cut the job time down considerably and saved you a lot of patience and swearing today I'm going to show you how to drill a small hole on the lathe with a very small drill and one of the reasons that we brake drills and with great taps is because we lose the feel for the interaction between that tool and the material that we're cutting now that particular term the field comes from a friend of mine Chet so if checked you're watching buddy this was inspired by you he used to tell me about the field the man said you gotta have the feel a thousand times and until you realize exactly what that means it's just gonna be another term but as you turn a twist drill on a lathe or you pull a handle on a mill if you can feel the material moving against the cutting tool then you're ahead of the game because you know when something's going wrong you know what something's going right you've got that feel and that's not really something you can teach someone you just have to have that in you and have to say yeah I can feel it I know enough drills getting sharp or when it's cutting good or not well when it comes to exceptionally small tools like small taps OAD taps or even smaller than that or little drills one millimeter or smaller you lose that feel with that tool because of the leverage because of the torque because of the attachments because they're just the sheer mass of the machine it's just consumed then there really is no feedback until it's too late then you know it's too late because it broke off it that kind of feedback comes through pretty quick anyway they do make specific attachments for doing what I'm about to show you when I look them up on the book the the cheap ones are around $400 and the expensive ones are around $900 so if you have a really expensive little hole or a very profitable part you feel like spending $900 there's $700 to drill one hole then have attic but I chose not to do that and I came up with an idea to modify an existing drill Chuck that I have to see if I could make it happen and it worked like a charm so I'm gonna share them with you today I'm gonna walk out to the bench I'm gonna grab a small drill I could tell you how small until we get there and we're gonna punch it through some material and I'm also not going to share that with you until we get out there so stake walk out the blade look at a small drill look at how that drill is going to be presented and utilized and I think you're gonna like easy okay guys this is the drill that I'm going to use for today's demonstration and just to put it in perspective we're going to push this into a piece of stainless steel because that's about the worst material you can think of for a small wire drill I mean you could get into a exotic cast lawyer inconel or one of those monel type nightmares but just for sake of this demonstration let's push this into a piece of stainless steel and to give you an idea how big that is this is a chunk of half-inch diameter stainless steel continues to roll away because this is all back row right now let's pull back and give you some idea what we're looking at all right half inch diameter stainless steel this drill bit is 26 thousandths of an inch in diameter I mean you could poke yourself in the finger with this and you think you had a splinter this is really small and if I wanted to I could just snap it off like a like a piece of glass it's very flexible even though it's so small I'm going to show you the Chuck I'm going to use to push this in there's nothing fancy about it but I did make an adapter for it this is a little Jacob's check straight shank and I'm going to put this in another Chuck so that I can close the jaws down to the point where I can actually hold this drill not all Chuck's will close all the way to nothing I believe this one will go down to 15th our 1/64 so let's set this up into Tails and there's still a trick about to happen here so I made an adapter for this guy that's gonna make this job a whole lot easier and it works very well so let's take a look let me shift the camera around and see if I can get close enough to actually show you what's going on okay I have an exceptionally small Center drilling my Jakob's check right now I'm gonna pop a center drill in that hole actually I'm just going to make a small dent it doesn't even have to be a center drill just something to track Center because the small drills are so flexible that if they're not even located they will walk all over the place [Applause] all right that is exceptionally small but that's all it's going to take let's back it up and look at the actual setup and show you the trick now I can be fairly sure that it's no great surprise to see somebody put a Chuck in a chuck it's not unusual standard tailstock there's an awful lot of mass here if you think you're going to feel that 26,000 diameter drill you've got another thing coming you may feel it but you're not going to feel it like this particular adapter will allow you to feel it instead of putting your Chuck directly into your other Chuck and you have a straight shank what an adapter in your Chuck and put your smaller Chuck in that adapter we are now eliminating the lead screw the mass the spindle and we're going to move out here and we're going to actually push this by hand this becomes your feed mechanism right here and the feedback that you'll get from the drill that's going to be in here against the material is absolutely amazing let me put the drill in here we'll get this thing repositioned and push it into that stainless like it's nothing it is very important to use clean fluid because you don't want any chips building up in front of the drill these drills are so small then the chips are so small that'll be very hard to tell if the drill is dull or there's chips in the bottom of your hole let's see how long it takes to go in about 200,000 [Music] [Applause] [Applause] today that is real time and you can see the difference between the projection here it's about a solid 3/4 of an inch the drill is flush with the face of the part and that is just under a half I would say that's a solid quarter of an inch worth of depth that was real time but did not use the crank on the tailstock I drove that in by hand if the drill were to start to grab you could actually let it go and let it spin with the material and back it out with the helix of the flute to reduce reduce the risk of snapping it off that's it that's all I got this is a very effective trick this is also called the micro drill Chuck adapter you can buy these if you want to spend 100 and a half and then put a check on it for whatever else that's going to cost you or do this this is good for the lathe this will not work in the mill because naturally in the mill the adapter is gonna spin and without a driver to drive the Chuck you're pretty much out of luck so not to say you couldn't rig it up I'm sure you can but this is a very effective lathe set up and it will give you tremendous confidence with small drills ok guys as promised here's your close up the drill survived nice hole this will serve you well it has served me well and it's a great confidence set up if you don't feel like snapping off a drill in a park good luck alright guys well I told you that was going to be something to see right if anyone would ever tell you that they can push a twist drill into a piece of stainless by hand without using the tailstock you would think that they were crazy but in fact the feedback that you get from that particular setup is amazing and you will probably never break another small drill ever again now I may have overestimated the price of these things when I said seven to nine hundred dollars you can get a a name-brand complete unit $6.99 $700 but they do make them somewhere in the 150 to $200 range if you look that's called a micro drill chuck adapter it's spring-loaded I used to call it a floating chuck or a spring-loaded chuck but the technical term is a micro drill chuck adapter it does have a two-piece three-piece spring-loaded spindle on it so you can put it in a bridge port or a mill and you can float it in as well it has a ball bearing race type collar just behind the chuck so that the chuck will spin but the car doesn't and you can feed it by hand as well you don't need to use the handle on the mill it's a fantastic tool to have and if you're the only guy in the shop that has one don't load it out rent it out and make a fortune you can retire early anyway hope you like what you saw it works really well try it if you have a straight shank chuckling around a small straight Chuck laying around make a sleeve for it stick it in a regular Chuck have at it you probably be glad you did anyway it's it to apply advanced innovations austin-texas about you
