Choosing the Right Reciprocating Saw Blades for Metal: Your Buying Guide
Reciprocating saws are powerful tools. They help you cut through tough metal. But the blade makes all the difference. This guide helps you pick the best blade for your metal cutting jobs.
Key Features to Look For
When you shop for metal-cutting blades, check these important parts:
1. TPI (Teeth Per Inch)
- High TPI (18-32 TPI): These blades have many small teeth. They cut thin metal very smoothly. Think of cutting sheet metal or conduit.
- Low TPI (6-14 TPI): These blades have fewer, larger teeth. They cut thick metal faster. Use them for pipes or heavy structural steel.
2. Blade Length
Blades come in different lengths, usually 6 inches or 9 inches. Longer blades cut deeper. Choose a length based on the thickest material you plan to cut.
3. Set and Kerf
The “set” is how the teeth angle out. This space, called the “kerf,” clears sawdust. A wider kerf helps keep the blade from binding in the metal.
Important Materials Matter
The material of the blade directly affects how long it lasts and what metal it cuts best.
Bi-Metal Blades
Most good blades are bi-metal. This means they combine two metals. The blade body uses flexible steel. The teeth use very hard high-speed steel (HSS). This combination offers both strength and durability.
Carbide-Tipped Blades
These are the toughest. They have small pieces of carbide brazed (welded) onto the cutting edge. Carbide lasts much longer than HSS. They handle very hard or abrasive metals well, like stainless steel.
Factors That Improve or Reduce Quality
Not all blades perform the same. Look closely at how they are built.
Factors That Improve Quality
- Welding Quality: Strong welds between the body and the teeth prevent breaking. Look for quality brazing on carbide blades.
- Tooth Design: Some blades have variable tooth spacing. This means the teeth sizes change along the blade. This design reduces vibration and cuts faster.
- Coatings: Some blades use special coatings (like titanium or Teflon). These coatings reduce friction, keeping the blade cooler and cutting longer.
Factors That Reduce Quality
Cheap blades often use lower-grade steel. They dull quickly. Poorly set teeth cause the blade to wander or bind during the cut. These blades break easily under heavy pressure.
User Experience and Use Cases
Think about what you will cut most often. This guides your choice.
Demolition Work
If you tear down old structures, you need tough blades. Use thick, durable bi-metal blades. They handle nails and screws hidden in the wood or metal without snapping immediately.
Plumbing and HVAC
For cutting copper, thin steel pipe, or aluminum conduit, you need a higher TPI (14-18 TPI). This gives you a cleaner cut without tearing the thin metal.
Heavy Fabrication
Cutting thick angle iron or solid steel bars requires a robust blade. Use a low TPI (6-10 TPI) blade, or invest in a carbide-tipped blade for the best performance and longevity.
10 Frequently Asked Questions (FAQ) About Metal Cutting Blades
Q: What does TPI mean for cutting metal?
A: TPI means Teeth Per Inch. More teeth cut thinner metal smoothly. Fewer teeth cut thicker metal faster.
Q: Can I use a wood blade on metal?
A: No. Wood blades have widely spaced, aggressive teeth. These teeth will instantly dull or break when they hit metal.
Q: Which blade material lasts the longest?
A: Carbide-tipped blades generally last the longest, especially when cutting very hard metals like stainless steel.
Q: How fast should I run my saw when cutting metal?
A: Always use a slower speed setting for metal. High speed creates too much heat, which dulls the blade quickly.
Q: What blade should I use for cutting thick steel pipe?
A: Use a blade with low TPI, like 6 or 10 TPI. This allows the large teeth to bite deeply into the thick material.
Q: Why does my blade keep getting stuck in the metal?
A: This usually means the blade kerf is too small for the material, or you are pushing too hard. Try using a blade with more set or slow your feed rate.
Q: Are blade coatings worth the extra money?
A: Yes, coatings reduce friction and heat. This makes the blade last longer, especially if you cut metal frequently.
Q: What is the best blade for cutting through old, rusty metal?
A: Use a durable bi-metal blade. The rust can be abrasive, so you need a blade that can handle some roughness without immediately failing.
Q: Does blade length matter if I am only cutting thin metal?
A: Blade length mainly affects cutting depth. For thin metal, a shorter blade is often stiffer and easier to control.
Q: How can I tell if my blade is dull?
A: A dull blade makes the saw vibrate a lot. It also cuts very slowly, and you have to push much harder to make progress.
