JessEm's all new 10 Piece insert ring set, These include JessEm's standard Tab-LockT design, plus we have added a convenient storage caddy that will hold 14 rings in total.
 
Insert rings included:
Blank, 1/4", 3/8", 1/2", 3/4", 1", 1-1/4",1-1/2", 1-3/4" and 2-1/4"
 
If you currently have the discontinued 4 piece insert ring set, they will nicely fit into the caddy as well.
 
These inserts allow you to use both larger and smaller router bits while maintaining support near the bit edge and provide maximum vacuum from the dust collection system.
