12mm-270mmTCT Hole Saw Metal Drilling

Our TCT Alloy Hole Saw is a high-performance cutting tool engineered for precise and efficient hole drilling in various metal materials. Crafted with premium YG10X tungsten carbide teeth, this hole saw boasts exceptional hardness, wear resistance, and heat resistance—key properties that ensure long service life and stable cutting performance even in tough working conditions. The saw body is made of high-quality 45# carbon steel, which undergoes rigorous heat treatment to enhance its toughness and structural stability, effectively preventing deformation during high-speed rotation.

Available in a wide range of specifications from 12mm to 270mm, this TCT hole saw offers versatile solutions for different drilling needs. It is perfectly compatible with electric drills and bench drills, suitable for both handheld and fixed-position operations. With a maximum working depth of 20mm, it excels in drilling holes on stainless steel (thickness ≤4mm), aluminum alloy, iron, angle iron, and cast iron (thickness ≤20mm), making it an ideal tool for metalworking, construction, automotive maintenance, and industrial manufacturing.

To ensure optimal performance and safety, please adhere to the following precautions: First, check if the center drill is tightly fastened before operation, then start the machine to verify the concentricity of the hole saw. Keep the hole saw perpendicular to the metal surface during drilling to avoid alloy tooth detachment; apply cutting fluid when drilling thick metal to reduce heat generation and extend tool life. Second, strictly follow the recommended drilling speed table to prevent overheating or damage to the saw teeth. Third, when using a hand drill, ensure the hole saw remains perpendicular to the workpiece; for higher precision and stability, bench drill operation is highly recommended.
