Lenox 56L Hole Saw – 3-1/2 in Bi-Metal, Faster Cuts & Durable Walls

Overview

The LENOX 56L hole saw is engineered to handle metal and wood tasks with confidence. Its bi-metal construction and enhanced tooth geometry bite into materials, shedding chips steadily and delivering a clean, decisive cut. Sized at 3-1/2 in (89 mm), this hole saw is a versatile option for common openings in electrical, plumbing, and woodworking projects.

Key benefits at a glance

• 2X more durable with 50% longer life than previous LENOX hole saws
• Increased wall thickness minimizes tooth loss and extends performance under load
• Optimized tooth design penetrates metal and wood with ease for faster cuts
• Larger, sharper teeth enable quicker hole prep and smoother entry
• SPEED SLOT staircase design enables easy plug ejection and reduces clogging

Performance in real-world use

In daily shop work, you’ll notice the bite of the teeth as they pull into material with a clear, confident feel. The 10% taller profile compared to earlier models helps maintain alignment, producing cleaner holes through two-by lumber and smaller workpieces. The thicker walls contribute to a stiffer cut path, helping you preserve drill speed and reduce wandering when starting a plunge.

The SPEED SLOT design targets dust and chips, guiding debris out of the kerf and away from the teeth. This practical detail makes it easier to finish a hole without frequent stoppages to clear plugs, which can help you stay focused on precision and speed.

Design, durability, and what to expect

The bi-metal core blends high-speed steel teeth with a durable steel backing to balance rigidity and resilience. The result is a tool designed for tough sessions, delivering consistent performance across metal and wood tasks while helping maintain cutting geometry over time.

• Designed for use with standard drills and common mounting hardware
• Maintains cutting performance across repeated openings in mixed materials
• Built to withstand busy workshop schedules and demanding projects
