DO I NEED THIS? (So long as you have a step bit, then no)

This bit is perfect for boring holes through the toe-kicks. 

NEVER USE Paddle bits! (or spade bits) -
They will damage the toe-kick, because you are boring the hole on the edge of the toe-kick right where it meets the sidewall of the cabinet. 

Other boring bits (like the Ridged Corkscrew kind) work too, but are slower and don't work as well. 

FYI: Home Depot / Lowes sells step bits too, but they cost $50 and are more for fine woodworking.
