It's easy to overlook jigsaw blades, but they are the most important part of the jigsaw tool, and they determine the quality, precision, and speed of cutting with a jigsaw tool. The correct jigsaw blade ensures success whether it is fine woodwork, cutting into sheet metal, or tile sculpting. Tools Warehouse is committed to making it easier for professionals and DIYers to choose the best jigsaw blades for wood and metal cutting. You can choose the correct jigsaw blade to get the desired result. 

A jigsaw is a multipurpose cutting tool, but the performance of the jigsaw tool is determined by the quality of the blade. Using the wrong jigsaw blade can lead to splintered edges, overheating, and wearing out too quickly. Therefore, it is important to know about blade types, tooth design and arrangement, and materials so you do not blend body materials. 

Blade Types: T-shank, U-shank, HSS, Carbide 

One of the first decisions to make when selecting a jigsaw blade is the type of shank and blade material. These features affect compatibility, cutting performance, and durability.

1. T-shank vs. U-shank Jigsaw Blades 

The two most common blade shank types are T-shank and U-shank.

• T-shank blades are the modern standard, widely used for their quick, tool-free change systems. They offer a tight, wobble-free fit, especially for Bosch, Makita, and DeWalt jigsaws.
• U-shank blades are less common but still used in older or budget-friendly jigsaws. These typically require a screwdriver or Allen key for installation.

For convenience and broader compatibility, T-shank blades are recommended and dominate today’s blade market.

2. High-Speed Steel Jigsaw Blades 

High-speed steel jigsaw blades are engineered for durability and heat resistance. They're ideal for cutting metals, hardwoods, and plastics, thanks to their ability to maintain a sharp edge under high-speed conditions. HSS blades are a go-to for users who need long-lasting, efficient performance on harder materials.

3. Carbide-Tipped and Carbide-Grit Blades 

Carbide blades offer unmatched hardness and wear resistance.

• Carbide-tipped blades are used for thick metals, stainless steel, and abrasive materials.
• Carbide-grit blades, which use a bonded abrasive edge, are perfect for cutting ceramic tile, fibreglass, and cement board.

Carbide options may cost more, but their extended lifespan and cutting performance justify the investment, especially for pros.

Material-Specific Blades (Wood, Metal, Tile) 

Not all blades are created equal. The best results come from using blades specifically designed for the material being cut.

1. Best Jigsaw Blades for Wood & Metal Cutting 

If you're handling both wood and metal regularly, a selection of bi-metal or HSS blades is essential. These blades offer excellent edge retention and can cut through wood framing and metal sheets without needing frequent replacements.

2. Fine-Cut Blades for Plywood 

Plywood can splinter easily, especially on the top surface. For a clean, chip-free edge, choose fine-cut blades for plywood with high TPI (teeth per inch) and reverse teeth designs. These blades are perfect for cabinetry and other finish carpentry applications.

3. Best Blade for Cutting Aluminium 

Aluminium requires a blade with a higher TPI and fine, sharp teeth. HSS or bi-metal blades are ideal. Look for blades rated specifically for non-ferrous metals to get smooth, burr-free cuts. A progressive-tooth blade also works well on thin aluminium sheets.

4. Jigsaw Blades for Curved Cuts 

Curves and intricate patterns require control and manoeuvrability. For these tasks, jigsaw blades for curved cuts are typically narrower, allowing tight-radius cutting without binding. Scroll blades or narrow wood-cutting blades offer the best results for detailed work.

Blade Selection Guide (TPI, Teeth Design) 

Selecting a blade involves more than choosing a material. Factors like TPI, tooth configuration, and blade size make a huge difference in both cut quality and blade longevity. 

TPI determines the speed and smoothness of the cut.

• Low TPI (6–10): Faster, rough cuts for softwoods and demolition tasks.
• Medium TPI (10–14): Balanced for smooth wood and light metal cutting.
• High TPI (14–24+): Precise cuts for sheet metal, PVC, or finish work.

Higher TPI blades produce cleaner edges but cut more slowly, making them ideal for finish-quality results.

2. Tooth Design 

Different cuts require different tooth styles:

• Ground teeth: Sharp and clean, suitable for fine wood cutting.
• Milled teeth: More aggressive and durable, best for fast, rough cuts.
• Wavy-set teeth: Common in metal blades for reduced vibration and smoothness.
• Reverse teeth: Point upward, reducing splintering on the material's top surface, excellent for laminated boards and veneered plywood. 

Maintenance & Safety Tips 

Listed below are the maintenance tips from Tools Warehouse. 

Maintaining Durable Jigsaw Blades for DIY and Pros

• Clean regularly: Use a resin remover or blade cleaner to eliminate gunk from wood and adhesives.
• Inspect often: Replace blades with chipped teeth, bending, or visible dullness.
• Store properly: Use blade holders or organisers to prevent damage from moisture and impact.
• Don’t overheat: Let the blade do the work. Excessive pressure generates heat and dulls teeth faster.
• Lubricate metal cuts: When cutting metals, apply a lubricant to reduce friction and increase blade life.
