LENOX Tools Hole Saw Bi-Metal Speed Slot Arbored 4-3/8 in - Durable

Our review of the LENOX Tools Hole Saw, Bi-Metal Speed Slot, Arbored, 4-3/8 in finds it best suited for tradespeople and serious DIYers who need a reliable hole saw for metal and wood tasks; the single biggest reason to buy is its improved durability and faster cutting thanks to optimized tooth geometry that cuts through metal more easily. The review covers cutting performance, durability, and everyday usability, and explains why the thicker walls and SPEED SLOT design matter when working with steel plates, doors, or lumber.

Key Features

• 2X more durable: Thicker walls and improved construction reduce tooth loss and extend life when cutting metal compared with the previous generation.
• 50% faster cutting: Enhanced tooth geometry and larger, sharper teeth let the saw penetrate metal more quickly for cleaner holes with less effort.
• SPEED SLOT staircase design: Wide, low slots and multiple leverage points make plug ejection straightforward and help prevent plugs from becoming stuck in the saw.
• Cleaner cuts in lumber: The saw is 10% taller than earlier models, which produces neater holes in two-by lumber and reduces tearout.
• Standard arbor compatibility: Uses a common arbor so it integrates easily with typical drill setups for quick tool changes on the job.

Who It's For

The LENOX Bi-Metal Speed Slot hole saw is aimed at professionals and dedicated DIYers who frequently cut through metal, wood, and composite materials and need a durable, reusable hole saw that maintains sharpness and resists tooth loss. It is particularly useful for electrical, plumbing, and carpentry work where clean, consistent holes are required for fittings and hardware.

Those who only make an occasional small hole for light home projects or who require specialty diameters for masonry or ceramic tile might look elsewhere; this product is optimized for general-purpose metal and wood cutting rather than specialist tile or concrete applications.

• Optimized tooth geometry and larger teeth deliver faster, cleaner cuts in metal and wood.
