Carbide Tipped Maintenance Hole Saw Kit, 11 Piece

The same nine sizes as the bi-metal maintenance kit, tipped with carbide instead. Carbide is what you want when the material would strip a bi-metal tooth — stainless, cast iron, fibre cement, plaster over lath, or a stud bay with embedded nail plates. It costs more up front and lasts far longer in abrasive material; in clean wood and mild steel the bi-metal kit is the better buy. Both arbors are included: ARB-2 (3/8" hex, fits 9/16" to 1-3/16") and ARB-5 (7/16" hex pin, fits 1-1/4" to 6").
