About This High-Quality TCT Carbide: MAZING hole saws are made of high quality TCT carbide (tungsten carbide tipped), providing fast, precise cuts and burr-free holes faster than conventional drills or hole saws. The high hardness, rust resistance and heavy-duty performance ensure ruggedness and durability. Cutting Efficiency Design: Triple-edged blades include an outer, center and inner blade for sharper, more efficient cutting of hard metals. Titanium-coated pilot drill bits protect carbide teeth from impact, springs effectively eject the chips easily, and the double chip removal hole design easily removes metal chips and provides effective cooling. Wide Application: These carbide hole saw kits cut metal materials up to 25mm thick quickly and accurately. Compatible with bench drills, handheld electric drills, impact drills etc. Perfect for cutting through hard metals, such as stainless steel, copper, iron, aluminum, also for plastics, fiberglass and other materials. Not for concrete, tiles, or stones. Safety Reminder: When drilling, keep the drill bit at a right angle (perpendicular) to the workpiece. Remember to add coolant during continuous high-speed drilling. Always wear safety goggles, hearing protection, gloves and a mask to protect against debris, noise and potential hazards.
