Applications & Features:--- Suitable for Titanium Alloy, Stainless Steel, High Carbon Steel, Cast Iron, Copper, Aluminum, Plastic, Wood--- Tungsten carbide offers great hardness and superior wear resistance. It delivers in high-speed machining, retains strength at high temperatures, and provides excellent compressive strength. Though brittle, impact-resistant grades exist. Its versatility makes it particularly suitable for cutting tools, dies, and wear partsUseful 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
