What Is Included:* hole saw, arbor (with drill bit), hex wrenchApplications & Features:--- Suitable for Stainless Steel, High Carbon Steel, Cast Iron, Copper, Aluminum, PVC Board, Acrylic Board, Wood--- M2 offers an excellent balance of key properties: high hardness , strong wear resistance, and good toughness. Its vanadium/carbon content provides effective edge retention against abrasion. M2 cutting efficiency in diverse applications, and remains a cost-effective core industrial alloy alloy for drills, taps, and cutting tools.Useful Tips:--- Do not touch the hole saw immediately after drilling because the temperature is too high. Add coolant or water when drilling metal. If Wear gloves and masks as needed and keep drilling slowly as the center drill passes through the material.
