Our Review
The AMZZ 23-piece bi-metal hole saw kit delivers solid performance for a budget-friendly option. The M42 HSS cutters handle wood, PVC, and soft metals reasonably well, with the 3/4" to 3" range covering most residential projects. The bi-metal construction balances heat resistance better than standard steel, though it doesn't match premium brands like Bosch or Milwaukee. Included mandrels are functional but feel slightly loose on some bits, affecting concentricity during cutting. For light-to-medium duty work, this kit punches above its price point, but expect slower feed rates and occasional vibration on tougher materials compared to professional-grade alternatives.
What We Like
- Complete 23-piece set with multiple mandrels eliminates frequent purchases for home projects
- M42 HSS bi-metal construction provides better heat dissipation than standard steel on extended cuts
- Excellent value for DIY workshops and occasional job site use under $40
Watch Out For
- Mandrels exhibit slight play, causing runout issues and uneven cutting on precision work
- Slower cutting speed on harder plastics and aluminum compared to cobalt alternatives
The Verdict
“A capable budget kit for homeowners and light commercial use, but mandrel quality control limits it from competing with premium professional sets.”
