If you’re planning to use your jigsaw for cutting metal, you’ve come to the right place. You already know that with the right blade, a jigsaw can cut through almost any material. Using specialized metal-cutting jigsaw blades, you can slice through tough materials like stainless steel, softer metals like aluminum, sheet metal, and even metal pipes.

Unlike other saw blades, jigsaw blades are often treated as consumables. This means you need to balance both price and productivity when selecting the right blade for your tasks.

We’ve spent hours researching to help you choose the best jigsaw blades for metal. Below, we’ll guide you through the essential factors to consider when purchasing jigsaw blades and review five of the top-performing products on the market. Let’s dive into the details!

What factors consider when choosing the best jigsaw blades for metal?

1. Blade Material

The material from which the blade is made significantly impacts its performance and durability. Here are the common types of materials:

• High-Carbon Steel (HCS): Flexible and economical, but not suitable for metal cutting.
• High-Speed Steel (HSS): Good for cutting metal but can be brittle and less flexible.
• Bi-Metal: Combines the flexibility of HCS with the durability of HSS. Ideal for thick and hard metal cutting, offering a lifespan that is often 10 times longer than single-type blades.
• Tungsten Carbide: Extremely durable and heat-resistant, able to cut hard materials like stainless steel. Typically more expensive but offers superior performance.

2. Blade Length and Thickness

• Length: It should be at least ½ inch longer than the thickness of the material being cut to prevent the blade from jumping.
• Thickness: Thinner blades are better for cutting curves. For instance, a 3/8-inch blade can handle gradual curves, while a ¼-inch blade is suited for tighter curves.

3. Blade Shank Type

• T-Shank: More popular for modern jigsaws due to their tool-free changing feature and compatibility with most jigsaws. They provide a secure fit and reduce blade slippage.
• U-Shank: Fits only universal jigsaws and requires manual adjustments for blade changes, which can be less convenient.

4. Tooth Configuration

The arrangement and number of teeth per inch (TPI) affect the cutting speed and finish:

• Lower TPI (6-14): Faster cuts but rougher edges, suitable for softer metals.
• Higher TPI (18-32): Slower cuts that result in smoother finishes, ideal for thicker and harder metals.
• For metal cutting, a TPI of 14-24 is typically recommended. A standard tooth direction is upward, while reverse tooth direction can assist in specific applications.
• Tooth Shape: A wavy set or milled teeth work best for metal as they provide a smoother cut and minimize chipping.

Pro Tip: For cutting thick metal sheets, a blade with a lower TPI (around 14-18 TPI) is recommended, while for thinner metals, a higher TPI (above 24 TPI) is better.

5. Cutting Performance

For specific tasks like cutting aluminum:

• Look for blades with a high tooth count (18-24 TPI) and a fine-toothed design for smooth cuts.
• Variable tooth pitch designs can help reduce friction and minimize heat buildup, which is crucial when cutting aluminum.

6. Durability and Lifespan

Choose blades that are built to withstand the specific demands of your project:

• Bi-metal blades offer extended lifespan compared to HCS or HSS.
• Tungsten carbide blades excel in cutting harder materials and maintaining sharpness.

7. Compatibility

Ensure the blade is compatible with your jigsaw model. T-shank blades fit most modern jigsaws, while U-shank blades are restricted to universal jigsaws.

8. Specific Applications

Consider what materials you’ll be cutting:

• For aluminum, a blade with carbide teeth and high TPI is ideal.
• For thick metal, choose robust bi-metal blades designed for that purpose.
• Stainless steel requires specific blades like a 7-inch jigsaw blade designed for this tougher material.

9. Price vs. Longevity

Since jigsaw blades are consumables, consider balancing cost with durability. Often, investing in a slightly more expensive, high-quality blade will result in more cuts per blade and reduced downtime for replacements.

Additional Recommendations

• For curved cuts, opt for thinner blades with small widths to maintain control and precision.
• Brands like Makita, Milwaukee, and Lenox also provide reliable metal cutting blades worth considering.

What is the Best Jigsaw Blades for Aluminum

When cutting aluminum with a jigsaw, a blade with a high tooth count and fine-toothed design is best. T-shank blades with carbide teeth are recommended, as they are durable and provide smooth cuts. A blade with a variable tooth pitch can also be helpful, as it can reduce friction and minimize heat buildup. The ideal blade should have at least 18 to 24 teeth per inch (TPI) for thin aluminum sheets, and 10 to 14 TPI for thicker sheets.

What Is The Best Jigsaw Model for Cutting Aluminum

It’s difficult to determine the best model for the best jigsaw blade for cutting aluminum as it can vary depending on the specific application and personal preference. Though standard TPI for aluminium menshoind above (10 to 18-24) but in the market popular brands has less TPI.

Some popular options include BOSCH T127D, BOSCH T127D 5-Piece, and DEWALT DW3755H 4-Inch 8 TPI. It’s recommended to choose a blade from a reputable brand known for producing high-quality jigsaw blades, and to consider the specific features and specifications that meet your cutting needs.

Focus Points How To Choose Jigsaw Blade for Aluminum

The main focus point for choosing the best jigsaw blade for cutting aluminum is to select a blade with high durability, accuracy, and smooth cutting performance. The blade should have a high tooth count and fine-toothed design to ensure a clean and precise cut, and a t-shank design with carbide teeth for added durability. A blade with a variable tooth pitch can also help reduce friction and minimize heat buildup. It’s also important to consider the thickness of the aluminum material being cut and choose a blade with the appropriate TPI.

1. Choose a blade with a high-grade steel construction, such as a bi-metal or carbide-tipped T-shank design blade. These types of blades can handle the heat generated from cutting aluminum.
2. Look for a blade with a high tooth count, such as a 10-14 TPI (teeth per inch), At least 18 TPI for thin aluminum sheets. The more teeth on the blade, the smoother the cut.
3. Make sure the blade is designed for aluminum. The teeth should be designed in a way that provides a clean, smooth cut.
4. Avoid blades that are too large for the job you’re doing. Blades with too many teeth can create too much friction and heat, which can cause the aluminum to melt or warp.
5. Choose a blade that is compatible with the type of jigsaw you’re using. Some blades are specifically designed for certain jigsaw models, so make sure you choose the right one.

FAQs

1. What is the best TPI for cutting metal?

For thin metals, 24 TPI is ideal, while for thicker metals, a TPI of 14-18 works best.

2. Can I use a wood jigsaw blade to cut metal?

No, jigsaw blades for wood have a low TPI and different tooth geometry, which is unsuitable for cutting metal.

3. How long do metal-cutting jigsaw blades last?

It depends on the blade material and the metal being cut. Bi-metal and tungsten carbide blades tend to last 2-4x longer than standard high-speed steel blades.
