Diamond Drill Bits - Why Should I Choose Them?Small diamond drill bits have a solid tip and therefore a larger surface area, so they last longer than small diamond drill bits, but may take longer to drill a hole.They are sturdier and therefore ideal for very hard and dense pieces of sea glass, very hard stones, gemstones, hard shells, bones and antlers. This tile hole saw is made of industrial grade carbon steel with a corrosion resistant nickel plated body. Thick corundum coating on tops provides superior cutting force for optimal drilling results.Specifications:Material: Carbon steelWeight: 0.35kgColor: SilverHole saw diameters: 6mm/0.24", 8mm/0.31", 10mm/0.39", 12mm/0.47", 14mm/0.55", 16mm/0.63", 18mm/0.71", 20mm/0.79", 22mm/0.87", 25mm/0.98", 28mm/1.10", 30mm/1.18", 35mm/1.38", 40mm/1.57", 50mm/1.97" Package includes: 15 * Diamond Coated Drill Bit
