Speed of the drill is required to heat and soften the hardened metal, which is then pushed out of the way through the flutes of the drill. Coolant would be detrimental to the process.
Love your videos. I found you while looking for stirling engines and see you have been on a hiatus until now. Will you be making more videos in the near future? Looking forward to a reply.
Hi Kevin, I am happy to see that someone enjoys my meager efforts. There are a number of projects on the go in my work shop and yes there will be videos in the future. But please don't hold your breath:-)) I've had some life changing events occurring, thankfully not health related, that take up some of my time. w
You were a machinist all your life and you operate machines with EXTRA baggy long sleeves?
Great lesson.
While not a machinist all my life, you make a very valid point! Long sleeves are a no-no when operating or near machinery.
A thousand apologies!
@@BasementEngineer Sorry for being harsh. That was drilled into my head for 46 years.
(tool maker/pattern maker/die maker)
@@FixNewsPlease No need to apologize. "No long sleeves" is a most important safety admonition that bears repeating often, as you proved to me:-))
Coolant may have been used
No, stellite drills are used without coolant.
The idea is to heat the hardened steel to the annealing point, and then scoop out the softened steel.
prob not good for taping though since the heat probably weakens the surrounding metal but maybe ok if going slow?

@@BasementEngineer yeah, ok; thanks.
maybe tapping would work anyway. i looked those up on amazon and didnt c them.

Nice. Ever ran an incinerator?
JM: Have you?
