With the 12-piece Hikoki 754254 all-round carbide hole saw set, you can make clean, accurate circular cutouts in a wide variety of building materials. Whether you are fitting recessed ceiling spotlights, running pipework, or installing wall boxes for electrical conduit, the carbide teeth cut smoothly through plywood, MDF, chipboard, aerated concrete, soft tiles, and PVC. Deep gullets quickly clear dust and chips, preventing overheating and jamming while maintaining smooth drilling progress. The set includes ten hole saw diameters from 16 to 76 mm along with two mounting arbors with pilot drills, all neatly organized in a durable storage case.
