[PROJECT] Spin Indexer Tailstock

[f350ca]

I don't think I've ever used the 45deg end on one of those bars, guess its to get the cutter to a shoulder. The 90 deg hole makes grinding easier for me, don't have to take the tool's angle into account. Do you not have a set of the carbide tipped boring bars, (come on) , I use them pretty much exclusively in the burring head. Cheap and cheerful Chinese but seam to hold up reasonably well.
