    Why would anyone want to do this? Limited drill bit diameter, no proper drill bit taper and no guarantee of straightness.

    This must be one of the most senseless endeavours ever. Surely drill bits are not all that expensive, even in India.

    I think it would depend entirely on how badly you need a drill bit in a size you don't already have. Particularly if you need it today, and your supplier is days or weeks away. I've lived most of my life in the 1st World, but I've lived in a couple of other places, too. If you need something bad enough, and are handy enough, and have a few tools, you can always make more. Yes, it is easier to to buy and have something shipped in. IF you can wait that long. From my own experience, I've seen Turks and Moroccans make stuff with bits of scrap that most machinists in the US would just send back for recycling or even just trash get used to make tools and equipment they needed.

    Would make more sense to use all that shop time to make a boring head.

    Sure, if you need big holes. How about smaller holes? I remember, long ago, some one showing how to make small drill bits out of music wire. Mostly spade bits, which are not the best thing for drilling in metals, but there has to be a way to do it. I tried a search for "making miniature drill bits" and got lots of info on pin vises, but this was the only how they're made video I saw on tiny drill bits:
    Though I must admit I didn't look very far.

    If I had a customer require precision holes that small, I'd be the first to sadly admit the task might be beyond my skill set
    Never try to tell me it can't be done

    Lots of very small boring heads out there. Commercial as well as DIY built...

    This boring head has a diameter range of 0.016" to 0.276".

    https://www.mmsonline.com/articles/w...st-boring-head

    Construction details included for this one...

    https://homews.co.uk/page199.html

    Of course, buying drills is far more practical than making them or building tiny boring bars. My quoted remark was sarcastic.

    I guess I should have known Harold Hall would have plans for a miniature boring head! The Kaiser boring head is also cute, but I expect it's way out of my price range! And I'm sleep-deprived, so probably wouldn't have recognized even mild sarcasm as such unless maybe it bit me.
