Package Include: 8 in hole saw, 1 pc arbor(with 1 drill bit), 1 pc drill bit for replacement, 1 pc hex key
Sharp and Durable: This hole saw is of bi-metal construction with high speed steel saw teeth and special flexible steel saw body for longer life and sharper edges
Lighter and Portable: After the structural upgrade, this holesaw achieves significant weight reduction while maintaining quality, ensuring labor-saving operation and efficient chip removal.
Easy to Use: Rotate the arbor and hole saw until nearly closed (avoid over-tightening), then align the locking pins with the guide holes and secure with screws
Wide Applications: Engineered for precision drilling on multiple materials including wood composites, plastic polymers, drywall panels, thin metal (except stainless steel), but not for brittle surfaces including glass, ceramic, tiles, granite, marble, porcelain, bricks, masonry, plaster, or natural stone to prevent chipping
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
