Choosing the Right Reciprocating Saw Blade for Metal Cutting
Reciprocating saws are tough tools. They need strong blades to cut metal effectively. Buying the right blade makes your job easier and safer. This guide helps you pick the best blade for your metal cutting tasks.
Key Features to Look For
When you shop for a metal-cutting blade, check these important features first.
1. TPI (Teeth Per Inch)
- High TPI (18-32 TPI): These blades have many small teeth. They cut thin metal, like sheet metal or conduit, very smoothly. They cut slower.
- Low TPI (10-14 TPI): These blades have fewer, larger teeth. They cut thick metal, like pipes or rebar, faster. They leave a rougher cut.
2. Blade Length
Blades come in different lengths (usually 6, 9, or 12 inches). A longer blade lets you cut deeper materials. Shorter blades are better for tight spaces.
3. Shank Type
Most modern reciprocating saws use a universal shank (often 1/2 inch). This fits most major saw brands. Always check your saw manual to confirm the fit.
Important Materials: What Makes a Blade Strong?
The material determines how long the blade lasts and what kind of metal it can handle.
High-Speed Steel (HSS)
HSS blades are good for general metal cutting. They handle softer metals well. They are often the budget-friendly choice.
Bi-Metal Blades
These are the most popular choice. They combine a flexible steel body with a strip of tough HSS welded onto the teeth. This design resists breaking and handles harder metals better than plain HSS.
Carbide Tipped Blades
These are the toughest blades. They have small pieces of carbide glued to the teeth. Carbide holds its edge much longer. Use these for very hard metals, like stainless steel or cast iron. They cost more but last much longer.
Factors That Improve or Reduce Blade Quality
Not all blades cut the same, even if they look similar.
Tooth Set and Rake Angle
The tooth set is how the teeth are bent side-to-side. A wider set clears chips better. The rake angle is the angle of the tooth face. A positive rake angle cuts faster but might wear down quicker on very hard metals.
Blade Coating
Some quality blades have special coatings (like titanium or black oxide). These coatings reduce friction and heat buildup. Less heat means the teeth stay sharper longer. This significantly improves cutting life.
Kerf Width
The kerf is the width of the cut the blade makes. A thinner kerf removes less material, which can sometimes speed up the cut, especially in thicker stock.
User Experience and Use Cases
Think about what you will cut most often.
- Plumbing Jobs (Pipes, Copper): Use a bi-metal blade with 14 TPI for fast cutting through medium-thickness pipes.
- Demolition Work: You need durability. Use a thicker bi-metal blade or a carbide-tipped blade. You might hit nails or screws, so a tough blade prevents snapping.
- HVAC/Sheet Metal: Use a fine-toothed blade (24 TPI or higher) to avoid bending the thin metal edges.
Always remember to use cutting fluid or oil when cutting thick or hard metals. This keeps the blade cool and makes the cut smoother. Always wear safety glasses!
10 Frequently Asked Questions (FAQ) About Metal Cutting Blades
Q: What is the best TPI for cutting thick steel pipe?
A: Use a lower TPI, usually between 10 and 14 TPI. More teeth would just clog up with the thick metal chips.
Q: Can I use a wood-cutting blade on metal?
A: No. Wood blades have very few teeth and a large gullet space. They dull instantly and often break when cutting metal.
Q: How do I stop the blade from overheating?
A: Use cutting oil or a lubricant on the cut line. Also, let the saw run at a moderate speed. High speed creates too much friction and heat.
Q: What does “bi-metal” actually mean?
A: Bi-metal means the blade uses two types of metal. A flexible body section supports sharp, hard teeth welded onto the edge.
Q: Are carbide blades worth the extra cost?
A: Yes, if you cut hard metals like stainless steel often. They last many times longer than standard blades.
Q: Does blade length affect cutting speed?
A: Not directly, but a longer blade can take longer, deeper strokes, which might seem faster for very thick material.
Q: Why does my blade keep breaking?
A: You are likely pushing the saw too hard, or you are using a blade with too few teeth for the material thickness. Also, check that the shank fits tightly in the saw.
Q: What is the best blade for aluminum?
A: Aluminum is soft. Use a blade with a lower TPI (around 10-14 TPI) and use a lot of cutting fluid to prevent the soft metal from welding onto the teeth.
Q: Should I use a fast or slow speed setting?
A: Always use a slower speed setting for metal. Metal cutting requires more force and less speed to manage heat and wear.
Q: How do I install the blade correctly?
A: Make sure the teeth point away from the saw body—toward the front nose of the saw. The teeth must point in the direction of the saw’s forward cutting motion.
