The Ultimate Buying Guide for Reciprocating Saw Blades for Metal
Choosing the right reciprocating saw blade for cutting metal makes a huge difference. The right blade cuts faster and lasts longer. This guide helps you pick the best one for your job.
Key Features to Look For
Several features tell you how good a blade is for metal cutting. Pay close attention to these points when you shop.
Tooth Pitch (Teeth Per Inch – TPI)
TPI is very important. It tells you how many teeth fit into one inch of the blade.
- Low TPI (e.g., 6-10 TPI): These blades cut thicker, softer metals quickly. They remove material fast.
- High TPI (e.g., 14-32 TPI): These blades work best on thin metals like sheet metal or conduit. They give you a smoother, slower cut.
Blade Length
Blade length affects how deep you can cut. Longer blades (e.g., 9 inches) cut deeper. Shorter blades (e.g., 6 inches) are better for tight spaces.
Set and Rake Angle
The “set” is how the teeth bend from side to side. This creates space for sawdust (or metal chips) to escape. A good set prevents the blade from binding. The “rake angle” affects how quickly the tooth bites into the metal. A positive rake angle cuts faster but can dull quicker on hard metals.
Important Materials for Metal Cutting Blades
The material the blade is made from determines its strength and lifespan, especially when cutting tough metals.
Bi-Metal (BIM)
Most good metal cutting blades use Bi-Metal construction. These blades combine two materials. The body uses flexible high-carbon steel so it won’t break easily. The cutting edge uses hardened High-Speed Steel (HSS). This combination gives you durability and sharp cutting power.
Carbide Tipped
For the toughest jobs, like cutting cast iron or stainless steel, carbide-tipped blades are the best choice. These blades have small, very hard pieces of tungsten carbide welded onto the cutting edge. They cost more, but they last much longer when cutting very hard materials.
Factors That Improve or Reduce Blade Quality
Blade quality affects performance greatly. Good manufacturing improves quality; poor design reduces it.
Weld Quality
The connection where the HSS edge meets the flexible body is crucial. A strong, clean weld prevents the teeth from breaking off during heavy use. Poor welds lead to early blade failure.
Coatings
Some blades feature special coatings, like Titanium Nitride (TiN). These coatings reduce friction and heat buildup. Less heat means the teeth stay sharper longer, improving the blade’s life significantly.
Tension and Straightness
A quality blade maintains perfect tension across its length. Warped or bowed blades wobble during the cut. This wobble creates excessive vibration, slows the cut, and wears the blade out much faster.
User Experience and Use Cases
Match the blade to the task for the best user experience. Using the wrong blade causes frustration and wasted time.
- Demolition Work: When you need to cut through mixed materials (metal studs, old pipes, wood with nails), use a durable Bi-Metal blade with a medium TPI (around 10-14 TPI). Speed matters more than a perfect finish here.
- Plumbing/HVAC: For cutting copper pipe, thin steel conduit, or aluminum flashing, a higher TPI (18-24 TPI) works well. This gives you cleaner cuts and less vibration.
- Thick Steel or Stainless Steel: If you regularly cut thick metal stock or very hard alloys, invest in a carbide-tipped blade. They handle the high heat and resistance much better than standard Bi-Metal blades.
10 Frequently Asked Questions (FAQ) About Metal Cutting Reciprocating Saw Blades
Q: What TPI is best for cutting standard plumbing pipe?
A: For standard steel or copper plumbing pipe (usually 1/8 inch to 1/2 inch thick), a TPI between 14 and 18 teeth per inch usually works best. This balances speed and cut quality.
Q: Can I use a wood blade to cut metal?
A: You should not. Wood blades have very few teeth (low TPI) and large gullets designed for wood chips. They will dull almost instantly when cutting metal, and the teeth might break off.
Q: How does heat affect my metal cutting blade?
A: Excessive heat is the enemy of sharpness. High heat softens the hardened steel edge, causing the teeth to dull very quickly. Cutting too fast or using the wrong TPI causes this heat.
Q: What is the main benefit of a Bi-Metal blade over a standard steel blade?
A: Bi-Metal blades are much more flexible. The body resists snapping when bent, while the HSS edge stays sharp. Standard steel blades are brittle and break easily when cutting metal.
Q: When should I choose a carbide-tipped blade?
A: Choose carbide-tipped blades when cutting very hard materials like stainless steel, cast iron, or thick structural steel (over 1/4 inch thick). They last significantly longer in these harsh conditions.
Q: Does the color or coating on the blade matter?
A: Yes, coatings like TiN (Titanium Nitride) help reduce friction and heat. This keeps the blade cooler during use, which extends the life of the cutting edge.
Q: How do I prevent the blade from binding in the metal?
A: Ensure your blade has a proper set (teeth bend slightly side-to-side). Also, make sure you are using enough lubricant or cutting fluid for very thick, hard metals.
Q: Should I use a lubricant when cutting metal?
A: Yes, using a cutting fluid or oil greatly improves performance when cutting thicker or harder metals. The lubricant reduces friction and carries away heat, making the cut smoother and the blade last longer.
Q: What does “raker tooth” mean on a reciprocating saw blade?
A: A raker tooth blade has teeth that are slightly offset, creating a cleaner cut. This design is very common and effective for general metal cutting applications.
Q: How long should a good metal cutting blade last?
A: This varies widely based on use. A good Bi-Metal blade might last for dozens of cuts through 1/8-inch steel. A carbide blade used for heavy-duty work might last for hundreds of cuts before needing replacement.
