Really useful - thanks! Also very interesting to see how the shape of the bottom of the drilled hole changes as the drill wears. I had no idea that would happen so fast.
Hi sir i need clarification , .086 -56 unc 3b thread Bottom tapping Min 1 1/2 full thread. What does it mean There is no mention of thread depth in the drawing
That is a number 2 machine screw. .086 is the nominal diameter of the screw., the depth of the whole to be tapped is 1.5" minimum and the 3b is a class 3 fit with A indicating internal thread, cut with a tap. I hope that helps.

That’s probably due to cutting it on a band saw instead of a milling machine. The drill stayed sharp ;)
@@Stubbornnut Ah - many thanks for the reply - it did seem like very fast wear so that makes more sense.
I wished I'd gone into engineering as a profession! Nice video and explanations as to the different types of taps.
Glad you liked it!
