Our Review
The MaxTool 5-1/2" bi-metal hole saw set delivers solid performance for tough materials thanks to its high-speed steel M3 construction and bimetal teeth design. The 5/8-18 arbor thread fits standard drill presses and handheld drivers, providing good versatility. The three-piece kit covers common hole sizes, and the bi-metal composition resists heat buildup better than standard carbon steel, extending blade life when drilling cast iron, stainless, and aluminum. However, the included arbor feels slightly loose on some drill chucks, requiring firm seating. Cutting speed demands careful feed pressure—too aggressive and teeth dull quickly. At this price point, it's fair value for occasional workshop use, though professional crews will appreciate the durability over cheaper alternatives.
What We Like
- Bi-metal construction withstands prolonged cutting in hardened steel and cast iron without premature dulling
- Standard 5/8-18 arbor fits most corded and cordless drill presses with minimal adapter needs
- Three-piece set covers frequent hole diameters, offering better value than single-saw purchases
Watch Out For
- Arbor exhibits slight play in some drill chucks, requiring tight grip to prevent wobble
- Rapid tooth dulling occurs under high-speed operation without precise feed control
The Verdict
“A capable mid-range hole saw set for DIY builders and small shops tackling tough materials, though professional-grade alternatives offer tighter tolerances.”
