CoCud 1-9/16" 40mm Hole Saw 4241 High Speed Steel Hole Cutter Silver Tone

• ★ Hole Saw Size --- Hole Saw diameter: 40mm/1-9/16 inch; center drill bit diameter: 6mm/0.24 inch; shank diameter: 7.5mm/0.3 inch; cutting depth: 3mm/0.12 inch; overall length: 70mm/2.76 inch
• ★ Wide Applications --- Suitable for various thin materials, such as copper, aluminum, mild Steel, PVC board, acrylic board, hardwood, plastic, cork, for automotive and boat repair and modification enthusiasts to use as professional tools
• ★ Special Coating --- Processed by CVD (chemical vapor deposition), with high hardness, high elastic modulus, high thermal conductivity, good self-lubrication and chemical stability
• ★ Good Feature --- 4241 delivers exceptional hot hardness. Its optimized alloy composition ensures superior wear resistance and enhanced toughness, reducing structural integrity concerns in high-stress operations. Excellent grindability facilitates precision machining of complex complex tool designs (drills, taps, milling cutters), lowering manufacturing costs and extending tool life
• ★ Useful 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
