    I took an old long BT-40 coolant through stud, clamped it in a pipe vise, and beat on it with a 2 pound ball peen hammer for several minutes. It marred but did not break or bend. I dismounted one...

    The part was still in the fixture but one side (the side with the carbide insert and seat stuck in it) appeared to have been pried up by the crash. The tool was still partially in the spindle when...

    I would be very surprised if this tool on this Brother machine had seen more than 2000 cycles. We primarily use the Brother for a family of parts that get 3rd op side holes in them. These parts...

    That is the only stud that has marks like that and they probably came from being flung around inside the retainer. The other ones that we got from Maritool and Yamazen all look virtually new.
