Check PriceHole Saw Set HYCHIKA 19 Pcs Hole Saw Kit
This is a popular, high-volume kit from HYCHIKA that excels on wood, drywall, and PVC but is not recommended for metal cutting. The hole saws in this set are made from high-speed steel (HSS) or carbon steel, which will dull quickly and potentially break when used on metal. Its inclusion here is for transparency—many consumers purchase this based on its high review count (over 9,200) without realizing it's unsuitable for metal projects.

- Extensive size range from 3/4" to 6" covers most wood/drywall needs
- Comprehensive kit with mandrels, drill bits, and accessories
- Very affordable for the quantity of pieces
- Excellent for general construction and remodeling
- High customer satisfaction for intended use (wood/drywall)
Cons (for metal cutting):
- NOT bi-metal—teeth will dull rapidly on metal
- High risk of tooth breakage when cutting metal
- Can create unsafe conditions (binding, kickback) on metal
- Wasted investment if purchased for metal projects
- No metal-cutting warranty or support
Important: This kit is fantastic for wood, drywall, and plastic applications but should be avoided for any metal-cutting tasks. For metal, you must choose a true bi-metal hole saw. The popularity of this kit often misleads buyers who don't read the specifications carefully.

Conclusion
Investing in a proper bi-metal hole saw kit is essential for anyone regularly cutting metal. Our top recommendations—the Milwaukee Hole Dozer kit for professionals seeking ultimate durability, the HYCHIKA 17-piece kit for excellent versatility at a moderate price, and the dedicated 6-inch saws for one-off larger holes—all deliver outstanding performance on metal.
