What it is for
The number pilots follow the rivet drills: #40, #30 and #21 are the holes for 3/32", 1/8" and 5/32" rivets on our drill chart. The #10 pilot is the 3/16" cleco size there; the 3/16" rivet hole is a #11. Check the pilot against your hole.
The microstop and the #40 and #30 cutters are the same items Yardstore puts in its home builder kit.
