KATA 8PCS Hole Saw Kit 1″ to 2-1/8″ for Wood
Best for DIY homeowners or crafters who need a complete starter set. It includes five hole saw sizes: 1″, 1-1/4″, 1-1/2″, 2″, and 2-1/8″, plus mandrels, drill bits, and a hex key. The kit uses heat-treated carbon steel with a black coating, suitable for soft woods, plywood, drywall, PVC, and thin plastics. Not intended for metal or tile. Choose this if you want an affordable, all-in-one kit for quick openings around the house.
Caution: Not designed for heavy metal drilling. The case helps with organization but ensure storage away from moisture to avoid rust on exposed edges.
1.5 Inch Hole Saw with M42 HSS Bi-Metal
Best for locksmiths, electricians, and DIYers needing a robust 1.5″ cut. Features M42 bi-metal teeth with 8% cobalt content for hardness and wear resistance. The triangle shank improves grip in chucks for heavy torque, enabling clean cuts through wood, plywood, plastic, drywall, and even some thin metals. Choose this if you frequently drill tight clearance holes or door hardware openings and want a longer-lasting blade.
Limitation: While versatile, it is optimized for thin materials; very thick metal requires a purpose-built metal hole saw.
LENOX Tools Bi-Metal 1-1/2″ Hole Saw
Best for users seeking increased durability and longer life. Lenox’s hole saw features a thicker wall and optimized tooth design aimed at easier metal penetration and extended service life. Suitable for metal, wood, and plastic, plus drywall. Opt for this when you need a reliable tool that resists tooth loss during rugged cuts.
Note: Performance is material-dependent; steel and hard metals may require slower speeds and proper lubrication for best results.

Best for general-purpose drilling with a ready-to-use cutting solution. The kit provides a long-lasting bi-metal construction and an arbor for a straightforward one-piece cutting experience. It’s well-suited for light to medium-duty tasks in wood, drywall, and plastics. Choose this if you want a dependable, all-in-one setup without hunting for separate components.
Caution: For hard metals or concrete, select a specialized metal hole saw and appropriate bits to avoid blade wear or snatching.

Best for contractors and serious DIYers who value American-made reliability and solid performance. Milwaukee’s Hole Dozer features bi-metal construction designed for durability and consistent cuts across varied materials.

Buying Guide: Key Considerations for 1.5-Inch Hole Saws
What material will you drill? If you mainly drill wood, drywall, and plastic, most standard bi-metal or carbon steel sets will suffice. For metal or tougher tasks, look for HSS, cobalt-containing teeth, or reinforced bi-metal designs.
What is your typical workflow? If you work with multiple hole sizes, a kit with multiple common sizes and a sturdy case helps with organization and quick changes. If you frequently encounter tight spaces, consider tools with solid chucks or shank designs that prevent slipping.
Arbor and compatibility: Ensure the hole saws include a compatible arbor and that the size range covers your intended opening. A single-piece arbor simplifies setup and reduces alignment issues.
Durability and life: Higher-quality steels and thicker walls offer longer life, especially when drilling through metal or dense composites. Be mindful of the feed rate and lubrication to maximize blade life.
Safety and technique: Use appropriate drill speed for the material. Start at a pilot hole if needed. Wear eye protection and secure the workpiece to prevent kickback or binding.
