Complete Your Kit – Avoid Downtime:
Pair this hole saw with our precision-matched accessories:
- Pilot Drills: Choose our standard TCT pilot with carbide-tip or HSS version for non Abrasive materials.
- SDS Type Arbors: Lock this hole saw directly into your rotary hammer drill for maximum torque when cutting through cement board, brick, or cast iron.
- Hole Saw Extensions: Add 12 in or 22 in of extra reach—perfect for drilling deep holes through thick walls, floor joists, or double-stud construction, and allows you to stand on the floor while drilling holes in the ceiling rather than balancing on a ladder.

Pro Tip: Pair this hole saw with our extension and arbor for the ultimate setup—drill deep holes safely and comfortably from the floor, making ceiling installations for recessed lighting and speakers faster and less fatiguing.

⚠️ Important: While this is a heavy-duty masonry hole saw, it is NOT designed for dense stone or solid granite—for granite, quartz, or extremely hard tile, please view our Diamond Grit Edge Hole Saws and Core Bits (sold separately).
