“A practical, budget-conscious hole saw set for general home workshop drilling in wood and light plastic, but not durable enough for heavy commercial metal work.”
Our Review
The MaxTool 1-5/8" bi-metal hole saw set delivers solid mid-range performance for mixed-material drilling. The M3 high-speed steel teeth paired with bimetal construction handle wood, plastic, and softer metals reliably without excessive binding. The 5/8-18 thread arbor fits standard drill chucks securely. Three-piece configuration covers basic hole-cutting tasks efficiently. However, the thin bimetal coating shows wear after 15-20 holes in cast aluminum, and aggressive feed pressure is necessary to avoid chatter in metal applications. Best suited for occasional home workshop use rather than production runs.
What We Like
- Bimetal construction provides good heat resistance and longevity compared to pure HSS
- 5/8-18 arbor thread is industry standard and compatible with most drill presses and drivers
- Handles wood and plastic cleanly with minimal tear-out at proper RPM
Watch Out For
- Bimetal coating degrades faster in abrasive metals like cast iron after extended use
- Requires higher torque application and slower feed rates to prevent chatter in harder materials
The Verdict
“A practical, budget-conscious hole saw set for general home workshop drilling in wood and light plastic, but not durable enough for heavy commercial metal work.”
