Tungaloy 1.125" 28.6mm Ø 5.66 D Drill 1.25 Shank TDXU-1125-05 XPMT 08T308 Insert 5xD PN 6718566 #2

I believe these take XPMT 08T3xx inserts such as XPMT08T308R-DJ  for example

A little rubbing wear on the flutes, insert pockets look great to me. Please examine the pics to judge the condition for yourself.
