🔹 Material & Structure:
★TCT Hole Saw:
Made of alloy steel body + tungsten carbide-tipped (TCT) teeth, providing superior hardness and wear resistance for high-intensity cutting tasks.
★Bi-Metal Hole Saw:
Made of high-speed steel (HSS) teeth + High temperature resistant spring steel body, offering a balance of hardness and flexibility, suitable for general metal and wood cutting.
🔹 Best Applications:
✅ TCT Hole Saw is ideal for:
-Cutting stainless steel, cast iron, hardwood, composites, fiberglass;
-Automotive, aerospace, shipbuilding, construction, furniture manufacturing, industrial processing;
-High-precision, high-volume production, reducing tool replacements and increasing efficiency.
✅ Bi-Metal Hole Saw is ideal for:
-Cutting general steel, aluminum, plastic, wood, drywall;
-Electrical work, plumbing, home renovation, DIY, mechanical repairs;
-Versatile and cost-effective, suitable for medium-scale cutting tasks.
🔹 How to Choose?
★For hard materials like stainless steel, cast iron, or hardwood → Choose a TCT Hole Saw for superior performance and longevity.
★For general metals, plastics, and wood at a lower cost → Choose a Bi-Metal Hole Saw for affordability and versatility.
Summary:
TCT Hole Saw is more professional, durable, and faster for industrial use, while Bi-Metal Hole Saw is more economical and practical for general-purpose cutting.
