Many owners report using this blade for everything from pruning branches to cutting EMT conduit. It is not the fastest blade, but its reliability and low cost make it a great choice for a starter set.

Best for Thick MetalPros
- Carbide teeth stay sharp longer
- Excellent for cast iron and steel
- Reduces blade changes

Bosch's carbide blade is designed for the toughest metal cutting jobs. The 14/18 variable TPI provides a smooth cut in thick materials like steel pipe, angle iron, and even cast iron. It is a premium blade for professional metal workers.
Owner feedback highlights its exceptional lifespan in abrasive materials. While the cost per blade is high, it often outlasts several bi-metal blades in heavy use, making it cost-effective for serious metal cutting.

- Low cost
Cons

This Lenox blade is purpose-built for tree pruning and landscaping. The 4 TPI and large gullets clear sawdust quickly, preventing binding in green wood. The 12-inch length gives you the reach to cut through thick branches.
Users report it makes quick work of limbs up to 6 inches in diameter. It is not suitable for demolition work, but for yard maintenance, it is a top performer that saves time compared to a handsaw.
Makita B-20431 6-inch Bi-Metal Blade
Best for Metal CuttingPros
- Fine teeth for clean metal cuts
- Good value multi-pack
- Reduces burr on pipe
Cons
- Slow in wood
- Teeth can clog with resin

Owner reviews note its consistent performance and durability. While it can cut wood, it is much slower than a dedicated wood blade. For a dedicated metal-cutting blade at a reasonable price, this is a strong choice.
What to check before buying a Sawzall blade
Tooth Per Inch (TPI): A lower TPI (3-6) is for fast cuts in wood and demolition. A higher TPI (14-24) is for smooth cuts in metal. Variable TPI blades offer a compromise.
Blade Material: Carbon steel blades are cheap and good for wood. Bi-metal blades are flexible and durable for nail-embedded wood. Carbide-tipped blades are the hardest and last longest in abrasive materials.
Blade Length: Shorter blades (6-inch) offer more control for cutting pipe. Longer blades (9 to 12-inch) are better for reaching through thick lumber or pruning branches.
Common mistakes to avoid
Using a wood blade for metal: This will dull the blade quickly and can be dangerous. Always match the blade material to the workpiece.
Forcing the blade: Let the saw do the work. Excessive pressure can cause the blade to bind, break, or overheat, shortening its life.
Ignoring blade shank type: Most modern saws use a universal shank, but always check compatibility. An incompatible blade will not lock in securely.
FAQs
What does TPI mean on a Sawzall blade?
TPI stands for Teeth Per Inch. It indicates how fine or coarse the blade is. Lower TPI cuts faster in wood, while higher TPI gives a smoother finish in metal.
Can I use a Sawzall blade to cut metal?
Yes, but you need a bi-metal or carbide-tipped blade with a high TPI (14-24). Using a wood blade on metal will dull it instantly.
What is the best blade for cutting nails?
A bi-metal demolition blade with a low TPI (6-8) is best for cutting through nail-embedded wood. The Milwaukee Torch is a top choice for this.
How long do Sawzall blades last?
It depends on the material and usage. A bi-metal blade can last through several hundred cuts in wood, while a carbide blade can last much longer in metal.
Are all Sawzall blades universal?
Most modern reciprocating saws use a universal shank that fits all standard blades. However, always check your saw's manual for compatibility.
What is the difference between a demolition blade and a pruning blade?
Demolition blades are bi-metal and designed to cut through nails and wood. Pruning blades are carbon steel with large teeth for fast cuts in green wood.
Can I sharpen a Sawzall blade?
It is possible but not recommended. The cost and effort to sharpen a blade often exceed the cost of a new one, especially for bi-metal blades.
What is the best blade for cutting cast iron pipe?
A carbide-tipped blade like the Bosch MRG1440D is best for cast iron. It has the hardness to cut through the abrasive material without dulling quickly.
Why does my blade keep breaking?
This is often caused by using too much force, a dull blade, or using the wrong blade type for the material. Let the saw do the work.
What is the best blade for cutting PVC pipe?
A fine-tooth bi-metal blade (14-18 TPI) works well for PVC. It provides a clean cut without melting the plastic.
