Henvo Hole Saw 3-1/2" (89mm) Heavy Duty Carbide with 2 Pilot Drill Bits - Metal Hole Cutter Cuts Stainless Steel, Iron, Copper, Brass, Plastic

Features

• 🌟Precision Cutting Power】Cutting Diameter = 89mm (3-1/2"),Hexagonal handles are included to make it easier to attach the carbide hole saw to the machine. Vertical Drilling Required for Stainless Steel, Cast Iron, Copper Plates.
• 🎯【Triple-Blade Innovation】Outer/Middle/Inner Blade Design Enhances Stability in Hard Metals. Titanium-Plated Pilot Bits Reduce Friction for Cleaner Holes on 1.18"（30mm） Thick Materials.
• 🔩【Higher Quality】Tungsten Carbide Tipped hole saw,2 titanium-plated drill bits, and a hex shank. Anti-rust oil has been pre-applied to ensure protection against rust.
• 🛠【Universal Drill Compatibility】Compatible with bench drills, magnetic base drills, and CNC systems, this precision-engineered tool effortlessly slices through stainless steel, aluminum, high-performance alloys, copper, and composite materials (including plastics, FRP, and PVC), delivering clean cuts while maintaining operational efficiency.
• 📌【Warm Reminder】For best performance, drill vertically to avoid bit breakage. When using the pilot bit alone, start with low torque and speed. Gradually increase the speed when the hole saw touches the material. Use cutting oil as lubricant to prevent bit overheating, burning or breakage.Above 1.5mm thickness, we recommend adding water or coolant.
