Honey Doo Drill Bit

[Music] let's just go for it huh see what happens here oh it cuts [Laughter] welcome back doc's tools i'm tom so this video we have a what i'm going to call a honeydew job and we're going to use the electronic helical indexer on the milling machine and we're going to make a cutting tool to do this particular job so stay tuned i think you'll like it [Music] [Applause] [Music] [Music] so [Applause] [Music] [Music] [Music] doink all right so now we can uh do our flutes on our honeydew drill here okay put it like that we're gonna use a tail stock here i'm just gonna bring this up we're not doing uh hyper accurate stuff here so um i'm not gonna sweat too much too many bullets here okay all right get into the starting position here actually back there yeah something like that it looks pretty good okay and then i'm gonna set the uh the end of the tool right there so i got a depth okay we'll come back to our starting position on the dro and then we're going to go set the uh the electronic indexer we're going to set the the bill dexter that's what i'm calling this uh we're going to initialize it here let's turn it on bring it back bring it to life and then we have to set the move angle which in this case because we're doing a two flute drill is 180 degrees and then we have to set the the ratio uh that determines the helix lead okay so right now we're set uh it's actually set uh for the correct number on this uh this little thumb switch here for the move angle so i'm just gonna go ahead and set that and it changed color so no i know it did something and now i'm gonna change it to the uh the proper number for the lead which we are going to use a five inch lead uh for our honeydew drill and that is a setting of eight one nine um so let's do this and get my hand out of the way and then eight one nine and that's that okay and so you change color okay and then we'll go uh now i'm gonna go back over to the uh the blank and you can see um what these settings translate onto on the indexer looks like let's first look at the uh the lead which is the rotation in relation to the the travel here and there you can see that's our lead okay very cool all right let's back to the start again let's see it just reverses all right so i'll get my starting position right there and let's just say we cut one of the flutes uh now i want to do a um an index 180 degree index i'm going to go ahead and do that and there she goes and that's 180 degrees okay and i always like to start on the zero here so i'm just going to bring it around again to my zero starting point here oops i didn't set it very well didn't i mr wizard um actually you know what i can i can tweak that because i like to be able to put the shot pin in there i can disconnect the encoder for a second there we go so that's that's a good starting place there that's where i want to be okay and so this gives me a reference if i get lost or do a bozo or something like that so guess what we're ready to cut some flutes on the honeydew drill all right you guys ready let's do this thing so i'm using a kind of a low cutting speed there let's take a fifty thousandths uh depth of cut here something like that and i'm just using uh this is this uh like dawn soap with water it works real good for uh um things like acrylic oh you know what i'm gonna double check make sure i didn't do something dumb here all right that's nice and tight all right let's see what happens there it goes and we are helixing this actually cutting pretty good figure out a stopping number there we go okay and then i'm just going to bring it up out of the cut to reverse it back okay and then take the backlash out all right let's go down to down to 100 actually that cut pretty good i'm gonna i'm gonna go uh full oinker here so i think i'm gonna fully cut one flute and then index uh index to the second flute [Applause] okay you guys get the visual look at that he's got a clear drill bit i do [Music] [Applause] all right so this is finished cut on this particular flute [Music] okay starting point and now we're going to index for our next clue [Applause] right there all right let's go in [Music] okay i'm gonna go a little more conservative on this glue here so [Music] okay that is it well that kind of looks like a drill bit doesn't it wouldn't you say so normally what you would do in this situation is you would relieve behind the cutting edge you see how this has a land on it and then it's relieved behind that and this keeps it from binding in the hole but the material that we're cutting with this probably not going to make any difference and frankly i'm kind of anxious to try it as probably you guys are too so let's uh um i'm going to pop this out of here and i'm going to go over to the uh belt sander and i'm going to put a cutting edge on the on the tip here and uh let's get to this uh honeydew drilling we're gonna sharpen this uh our uh our honeydew drill here on this belt sander here uh because i have speed control here i can run it pretty slowly and i don't get so much of a melty cut and then and then for sharpening large drill bits it's really nice to have a kind of a wide platen uh to work with there so let's uh [Music] adjust the tracking a little bit pretty good and a lot of you guys that know me uh know that i sharpen drills kind of backwards from the rest of the universe right and um so some people are probably going what the heck is he doing there but it worked for me that's how i taught myself and uh yeah you see how melty that gets there this felt might be a little fine for this try lighter pressure okay it's starting to look like it'll cut still don't like all right here we go okay so i got my relief i'm almost to the front edge there pretty close oh yeah sweet i think that'll work all right what do you say we go drill something well this is our test subject and here's our tool that we made so the question is will it blend or will it cut let's check it out [Applause] all right so and should we do a uh a polar or equatorial uh cut actually we're gonna do both so that's actually this the stem and um let's just go for it huh see what happens here oh it cuts [Laughter] yep actually smells good uh equatorial cut anyone well i think it works yeah let's see got the old shop knife here what do i want to do here okay look at that intersecting holes all right thanks for watching [Applause] [Music] foreign
