Gears in gas powered core drill
Gears in gas powered core drill
(OP)
Were busting teeth in service
Tested them at 60 Rc,,, so I tempered them at 450C back to 48Rc
Boss flew off handle,,, said they are too soft now
Please advise
My estimate is that 48 is not too soft
Gear mat,l unknown

Thanks for your valuable time
Will look at failed teeth under microscope
