Luomorgo 4.72" 120mm TCT Carbide Hole Saw Tungsten Carbide Tipped Hole Cutter with 2 Pcs Titanium-Plated Pilot Drill Bit for Metal Iron Steel Wood Plastic

Feature: The unique three-blade design of the teeth includes the outer blade, middle blade and inner blade, so that each tooth can be easily stressed during the cutting process, thus making the cutting smoother, more accurate and faster. Step pilot bits are designed to protect carbide teeth as the pilot drills through cutting material. This hole saw cannot be used for concrete, tile and stone. Don't forget to use a lubricant (water or some kind of oil) to prevent the bit from overheating.
