The Starrett KMP03031-N 6-Piece Tungsten Carbide Tipped General Purpose MPH Hole Saw Kit includes three hole saws in diameters 2-1/8'', 2-9/16'', and 3-5/8'', one arbor with carbide tipped pilot bit, and two carbide-tipped pilot bits. Carbide-tipped hole saws last longer and are harder than bimetal for more abrasive materials such as wood, MDF, plastic, building bricks, and ceramic tiles. The saws have a special tooth set designed for more efficient removal of difficult-to-cut materials than bimetal hole saws. 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.

The L.S. Starrett Company manufactures precision measuring tools, metrology and testing equipment, and saw blade products. The company was founded in 1880 and is headquartered in Athol, MA.
