Hole Saws

Diablo Snap-Lock Plus carbide-tipped hole saws, all with a 2-3/8 in. cutting depth. The Snap-Lock arbor drops the saw on and off without a wrench, which is what you notice when you are changing sizes on a ladder. Carbide teeth hold an edge in nail-embedded wood, fiber cement and thin metal where bi-metal dulls. Kits ship with the mandrel and pilot bit; individual saws do not, so order an arbor if you do not already have one.

Sizes include 1-3/4, 2, 2-3/8 and 2-1/2 in., all on the Snap-Lock system.
