Excellent demo of drill making. This is very useful for making the larger drill bits from 25 mm and bigger because the expense of buying a drill bit, is far more than the time it takes to make one. Especially in South Africa where our currency is worth nothing. Doing this with a very high carbon steel would be succesful.
Excellent work. A couple things I will add for others who will try to do this- have suction on what you're doing on the lathe when you're grinding you do not want grinding dust or grit on your lathe. Grab the Finish bit close to the tip in aluminum soft jaws to chop off the knob with the grinder, you don't risk distorting it as much or marring the shank. You gave primary relief to it only when cutting the helix behind the cutting edge with the flat endmill, but you left it full diameter when you ground it to size. Ideally you would use a radius bit slightly offset axially to put a very shallow radial relief on that leading edge, only a tiny bit of relief will dramatically lower the heat in cutting, like 0.002" over that distance is enough so that only the very edge is actually touching your work. I would have also used an oven to do the tempering, much more exact results even in the house oven. Otherwise fantastic work I've seen very few people do this type of drill from scratch. You can also get around a lot of things if you slot the tip to take drill tip carbide inserts that you can swap out when they dull. I'm a prototype machinist and ex tool and die maker fwiw. Especially like how you stamped it and then finish ground it- cleaning the raised letters from stamping don't affect the concentricty of the shank. Great work 💪😎

The spirals coming out of the lathe drilling operation were something else - the biggest string snakes I've seen from any drill bit.

@@Mastermind- I don't like dull slow drill bits. So in that sense it is excellent. I suppose the drilled hole could possibly be a bit "micro wavy" from the large continuous burrs, if there is a downside. Personally I am very pleased with my metal drilling when I get burr snakes - it goes so quickly and requires so little pressure comparatively. It's just very pleasant compared to the alternative.
You’re out there making your own drill bits meanwhile I’m struggling like crazy to keep my store bought ones sharp… definitely need to put more time into learning how to sharpen drill bits
Отличный мастер! Отличная работа! И избыток свободного времени...
Я думаю это в качестве демонстрации было сделано. Так как стандартные сверла не сложно купить, а вот под разные резьбы к примеру дюймовые, не просто подобрать сверло необходимого диаметра. Хорошая работа, молодец!

Congratulations 💐💐💐💐 To You. You have such great skills. I have nothing to say. Sir I don't even know how to sharpen a Drill Bit more or less make one. I have enjoy watching your videos. And I can't even start to know how you were making the Drill Bit. Again congratulations 🎉🎉 to you. You have a lot of practice And a lot of Hours under your Belt to have learned how to make one.

Since it had an oil quench I imagine it was an 01 type oil quenching carbon vanidum chrome nickle phosphate buffered steel, silver steel. Remove the vanchromnickpho part and add in slicia, more and different acids and alloying elements... the Era of Steel is with us still in the current era.

@@Mastermind- yes,small drills will brake like glass. But above 10mm not really a problem if a bit harder. You should try freez treatment. Put in dry ice or liquid nitrogen and let cool down. Helps a lot from braking out chips.Call cryogenic threatment.
Excellent.. after this you can make the drill bit smaller, size 1mm or less😁

@@Mastermind- that's logic but for aan steering axle you must have an nut and an spiral realy fitting and smooth passing, up and down, so it must be exact, maybe there is an 'lathes engeneerings trick ' for that ?

Axial moved by half a step of the helix...
Yeah I may do the same but with what I think is far easier spotting drills - they are hard to get and center drills are not good at making good starting point for drills - they are for lathe centers.
Was it hss or over grade of steel?

Hardening and tempering
what did you do to the lathe so it has such a fast feed rate? btw, you overheat the drill when austenizing way too much for best results (at least it gets white in the vid).
