I am a retired Journeyman Machinist and made these years ago and no longer use them. I made them from alloy steel and sent them to heat treat for stability. The 12 inch,1.125 high one uses 1/4 inch triangle carbide inserts with 13 new ones provided. The 10 inch is 7/8 high and uses 5/16 HSS tooling. The 8 inch is 5/8 high and uses 1/4 inch HSS tooling. The other 8 inch is 1/2 inch high and uses 3/16 HSS tooling. The 7 inch one is App. 3/4 high and uses 1/8 inch triangle inserts 17 new ones provided. The other bar is a piece of junk but works with 1/4 inch HSS tooling. What you see in the pictures except the tape measure is what I will ship out to you upon the winning bid. Thanks!
