The Starrett KMX25061-N 31-Piece Bimetal, Carbide-Tipped, and Cordless Smooth Cut Electrician's Hole Saw Kit includes 14 bi-metal hole saws in diameters 3/4'' to 4-3/4'', eight carbide-tipped hole saws in diameters 3/4'' to 2-1/2'', three smooth cut cordless hole saws in diameters 3/4'' to 1-3/8'', two arbors, two carbide-tipped pilot drills, one arbor adapter, and one ejector spring. A combination of bimetal, carbide-tipped, and smooth cut hole saws make this kit best for cutting through a wide range of materials, including wood, metal, mild sheet steel, thin nonmetallics, PVC , man-made building materials, fiberglass, and plaster board. The bimetal saws have a variable tooth pitch and positive rake angle for efficient cutting and chip evacuation. The carbide-tipped saws have a special tooth set designed for more efficient removal of difficult-to-cut materials than bimetal hole saws. Smooth cut cordless hole saws offer reduced vibration compared to bimetal hole saws for smooth cuts when used on cordless drills. The kit comes in an aluminum case with a handle.
Hole saws cut holes in various materials with a drill. They are hollow cylinders made of metal with teeth on one end and an arbor hole or built-in arbor on the other end.
