Ever tried cutting through tough metal with the wrong saw blade? It’s frustrating! You might see sparks fly, but the blade barely scratches the surface, or worse, it breaks halfway through the job. Choosing the perfect reciprocating saw blade for metal cutting can feel like a confusing maze of numbers, materials, and teeth counts.
The right blade makes metalwork fast and easy. The wrong one wastes time, ruins materials, and can even be dangerous. Many people struggle with knowing which blade can handle thick steel versus thin conduit, leading to dull blades and costly replacements. Understanding the key differences is vital for any DIYer or professional who works with metal.
This guide cuts through the confusion. We will show you exactly how to read blade labels, understand TPI (teeth per inch), and select the best material—like bi-metal or carbide—for your specific metal project. By the end of this post, you will confidently pick the blade that slices through metal like butter, saving you time and money on every cut.

The Essential Buying Guide for Reciprocating Saw Blades for Metal
Reciprocating saws are powerful tools. They need the right blade to cut metal well. Choosing the correct blade makes your job faster and safer. This guide helps you pick the best metal-cutting blade.
Key Features to Look For
When buying a blade for cutting metal, look closely at these parts.
1. TPI (Teeth Per Inch)
TPI tells you how many teeth fit on one inch of the blade. This is very important for metal.
- High TPI (18-32 TPI): These blades have many small teeth. They cut thin metal, like sheet metal or conduit, very smoothly.
- Medium TPI (10-14 TPI): This is the best all-around choice. It works well for medium-thick materials like steel pipe or angle iron.
- Low TPI (6-10 TPI): These blades have fewer teeth. They cut thick, tough metal like heavy steel beams quickly. They leave a rougher cut.
2. Blade Length
The blade length affects how deep you can cut. Longer blades (9-12 inches) cut deeper. Shorter blades (6 inches) are better for tight spaces. Match the blade length to your saw and the material thickness.
3. Blade Set and Gullet Size
The “set” is how the teeth angle out. A wider set clears chips better. The “gullet” is the space between the teeth. Larger gullets clear more metal shavings, which stops the blade from overheating.
Important Blade Materials
The material of the blade decides how long it lasts and what kind of metal it cuts.
Bi-Metal (Bimetal) Blades
These are the most common and best choice for general use. They combine two metals. The cutting edge uses very hard, fast-cutting metal (like High-Speed Steel or HSS). The body uses flexible spring steel. This combination makes the blade strong but prevents it from snapping easily.
Carbide-Tipped Blades
These are the heavy-duty option. They have small, very hard pieces of tungsten carbide brazed onto the teeth. Carbide cuts extremely hard metals (like stainless steel) and lasts much longer than bi-metal blades. They cost more upfront.
High-Speed Steel (HSS) Blades
These are less common now. They are decent for softer metals but wear out faster than bi-metal blades when cutting harder materials.
Factors That Improve or Reduce Quality
Good blades perform better and last longer. Poor quality blades break fast.
Factors Improving Quality:
- Good Weld/Brazing: The connection between the teeth and the blade body must be very strong. A poor weld means the teeth will fly off under pressure.
- Progressive Tooth Design: Some blades slowly increase the TPI from the heel to the tip. This design handles different material thicknesses well and reduces vibration.
- Corrosion Resistance: Blades treated to resist rust last longer in storage or damp environments.
Factors Reducing Quality:
- Thin Material Body: If the steel body is too thin, the blade will bend or warp when cutting thick steel.
- Soft Tooth Material: Teeth made from soft metal dull quickly, forcing you to stop and change the blade often.
User Experience and Use Cases
Your project determines the perfect blade.
If you are demolishing old pipes, you need speed and durability. Use a **low TPI bi-metal blade** (around 8 TPI) and a longer blade (9 inches). You will get a fast, rough cut.
If you are installing new metal shelving, you need clean edges. Choose a **medium TPI blade** (14 TPI) for smoother results on angle iron or square tubing.
For cutting through very thick, hard stainless steel bolts, **carbide-tipped blades** are necessary. They handle the extreme heat and stress without failure.
10 Frequently Asked Questions (FAQ) About Metal Cutting Blades
Q: What is the most important thing to check before buying?
A: Check the TPI rating. It must match the thickness of the metal you plan to cut most often.
Q: Can I use a wood-cutting blade on metal?
A: No. Wood blades have a very low TPI and large gullets. They will dull instantly and likely break when hitting hard metal.
Q: How do I make my metal-cutting blade last longer?
A: Always use cutting fluid or oil when cutting thick or hard metals. This reduces friction and keeps the blade cool.
Q: What does “bi-metal” actually mean?
A: It means the blade uses two different types of metal fused together—one for strength and one for cutting hardness.
Q: Are carbide blades always better than bi-metal blades?
A: Not always. Carbide is better for very hard metals. For soft metals like aluminum, a good quality bi-metal blade works just fine and costs less.
Q: What happens if my TPI is too high for the metal?
A: If the teeth are too close together for thick metal, the gullets fill up with chips. The blade overheats, slows down, and wears out very fast.
Q: Should I use a short or long blade for cutting metal pipe?
A: Use a longer blade (9 inches) if the pipe is large in diameter. This allows the saw body to clear the pipe while cutting.
Q: Are expensive blades worth the extra money?
A: Yes, generally. More expensive blades usually have better materials and superior welding, meaning fewer blade changes and less frustration.
Q: What speed setting should I use on my saw for metal?
A: Always use a slower speed setting for metal. High speeds generate too much heat and damage the teeth quickly.
Q: How can I tell if my blade is dull?
A: If the saw starts vibrating a lot, or if you have to push very hard to make the blade cut, the blade is dull and needs replacing.
