Package Includes: 1 pc 7" 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 achieved significant weight reduction while maintaining original quality, ensuring easier handling and more 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: 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
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
