Bi-Metal Speed Slot Arbored Hole Saw 4-1/8 in - Durable Cutter

In this review the Lenox 4-1/8 in Bi-Metal Speed Slot Arbored Hole Saw is evaluated for tradespeople and serious DIYers who cut metal, wood and composites and need a hole saw that lasts through repeated jobs. The bottom line: this hole saw stands out for its combination of durability and fast cutting thanks to upgraded tooth geometry and thicker walls, making it a practical choice when clean, consistent holes and easy plug removal matter.

Key Features

• 2X more durable: Thicker wall construction improves resistance to tooth loss and extends tool life on metal cutting tasks.
• 50% longer life: Enhanced bi-metal construction delivers longer service life than previous LENOX hole saws when used on steel and other metals.
• Optimized tooth design: Larger, sharper teeth and refined geometry let the saw penetrate metal with less effort and more consistent cut quality.
• SPEED SLOT staircase: Wide low slot with multiple leverage points makes plug ejection fast and prevents plugs from getting stuck during work.
• Cleaner cuts in lumber: Taller cutting height yields neater holes through two-by lumber and reduces tearout.

Who It's For

The Lenox 4-1/8 in Speed Slot hole saw is best for electricians, plumbers, door and hardware installers, and contractors who regularly cut metal wall plates, steel doors, plywood and dimensional lumber and need an arbor-mounted hole saw that resists tooth loss and ejects plugs easily.

It is less useful for users who only need occasional plastic or thin-gauge hobby cuts where an inexpensive single-use saw would suffice; heavy-duty demolition or abrasive materials may still wear any bi-metal blade over time.

Pros & Cons

Pros

• Highly durable construction reduces tooth loss and improves longevity for metal work.
• Sharp, larger teeth and improved geometry deliver fast, clean cuts and good cut quality.
• SPEED SLOT staircase design simplifies plug removal and clears chips to keep cuts consistent.

Cons

• Heavier, thicker walls add mass compared with lightweight hobby saws and may be overkill for infrequent small plastic cuts.
