If you’re after a solid set of blades that won’t quit when the job gets real, the Lenox 20577850R Bi-Metal Blade 8-inch 5-Pack is exactly that — a work-ready bundle of reciprocating saw blades built to handle wood, metal, pipe and nails without whining. What really stands out is that these aren’t some flimsy one-cut wonders; they’re designed to bend a bit and keep going instead of snapping the first time you hit steel.

In practice this pack gives you five 8-inch blades with a 10/14 TPI setup that’s meant for general purpose cutting — and weirdly enough, that’s one of the most useful configurations you can have in your kit. The bi-metal construction mixes springy backing steel with tougher tooth material, so you get moderate flex but real durability where it counts.

Key Features:

• 5-Pack Blades - Stock up your saw so you’re not swapping blades every time you hit thicker material.
• Bi-Metal Construction - The blend of metals lets the blade survive twisting and shock without quitting early.
• 10/14 TPI Tooth Pattern - A pretty versatile tooth count that slices through wood with nails and thin metals without bogging down.
• 8″ Length - Deep enough cut for framing, demolition and most on-site cuts without struggling.
• Rigid Cutting Edge - Keeps cuts straight and controlled, so you can follow the line instead of chasing it.

Applications

On a job site or in the shop, this Lenox reciprocating saw blade pack shines wherever you need a reliable general-purpose blade — ripping out old framing, cutting pipe, trimming lumber, making quick demolition cuts or slicing through mixed materials without switching blades every other cut.

Why Choose This Model

The bottom line is, you don’t buy this expecting fancy specialty cutting — you buy it because it works. It cuts fast enough without whining, tolerates abuse better than stamped-steel toys, and that matters a lot on a job site where downtime equals lost dollars. If you’ve ever snapped a blade at the worst moment, you’ll appreciate how these stay intact longer.

Technical Specifications Explained

• Blade Length – 8 inches - Gives you decent cutting depth in most materials without the blade flopping around.
• Teeth Per Inch – 10/14 - A medium tooth pitch that balances speed and smoothness for general work.
• Blade Thickness – ~0.05″ - Thick enough to stay straight, thin enough to slice without fighting the cut.
• Material – Bi-Metal - Two metals fused for toughness and resistance to cracking under load.
• Pack Quantity – 5 - Enough blades to keep you going through an entire day of cutting without constant changeouts.

Who Should Buy This

If you’re a contractor, fabricator, remodeler or serious DIYer who uses a reciprocating saw a lot, then having a pack of these general purpose Lenox blades in your box means fewer stops and fewer snapped blades — which beats buying single blades every week, plain and simple.

But don’t get this expecting specialist metal-only or ultra-fast wood cutting — it’s a workhorse, not a racehorse, and that’s exactly why a lot of pros keep it handy.
