Industrial Quality: Made from high-quality tungsten carbide (TCT). This industrial-grade drill bit is extremely durable and suitable for all hard materials. It lasts longer than bimetal and HSS drill bits. Advantages: The TCT hole saw has a longer lifespan than conventional metal hole saws and is perfect for drilling hard metals. Ideal for hard metals, stainless steel plates, square tubing, iron, cast iron, wood, and other sheet metal. Not suitable for concrete, tile, or stone. Application Instructions: Add coolant if necessary. Reduce speed while drilling. If chip ejection is uneven, stop drilling and clean the workpiece. After use, dry or oil the drill bit to prevent rust and extend its lifespan. This excellent drill bit makes drilling easier and improves work efficiency.
