Frustrating part is, I’m not sure what I did wrong
Carbide 300wm reamer (used. 1st time using it)
Standard floating reamer holder
205 rpm
Barrel Flush at about 1/2 power
Stainless Rem varmint contour
Pre drilled 1.5” in with .390 bit
Boring bar first half inch to .450
Reamer was feeding extremely well then the cutting oil spray changed a bit and before I could stop it, the reamer broke off in there with about half inch left to go. My guess, it hit the end of the pre drilled section and grabbed??? Chips seemed to be clearing out well. Ideas?
