Self-Centering Drill Press Jig (Item 92046)

V-groove aluminum jig that bolts to a drill press table — automatically centers the bit on tubes, pipes, dowels, or any round stock, no marking or center-punching needed.

Very strong review base (241 reviews, 4.8 stars) — used for both wood dowels and metal conduit/tube work. Tip: flattening the bottom slightly improves accuracy.
