Applications & Features:--- Suitable for Metal Sheet, Wood, Plastic Plate --- M42 delivers with exceptional thermal integrity and heat resistance due to its high cobalt content (8%). This enables superior cutting performance and wear resistance at high temperatures,offering outstanding edge retention, abrasion resistance, and longer tool life when machining tough, abrasive, or hard materials like stainless steelsUseful 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. If the hole saw encounters unusual resistance or vibration during operation, stop drilling immediately
