About this item

• Package Includes: 1 pc 4' hole saw, 1 pc arbor with drill bit, 1 pc pilot drill bit (replacement), 1 pc hex key
• Sharp and Durable: Crafted from bi-metal construction, this hole saw features high-speed steel teeth and a flexible steel body for enhanced durability and sustained sharpness
• Lightweight and Portable: Through structural innovations, this holesaw achieves significant weight reduction while maintaining quality, ensuring labor-saving operation and efficient chip removal
• Wide Applications: Engineered for precision drilling on multiple materials including thin metal (except stainless steel), wood composites, plastic polymers, drywall panels, but not for fragile surfaces including glass, ceramic, tiles, granite, marble, porcelain, bricks, masonry, or natural stone to prevent chipping
• Easy Assembly: Insert the arbor's pilot drill bit through the central hole on the back of the hole saw, then rotate the arbor to tighten it
• Attention: Don't touch the hole saw immediately after drilling because of high surface temperature; Apply water/coolant and reduce feed speed when drilling metal materials; Stop drilling immediately if abnormal vibration occurs
