Jigsaw blade Smart HSS 21 TPI for metal, set of 5

Smart HSS 21 TPI jigsaw blades (set of 5) are T-shank blades designed for cutting metal with a focus on fine, precise edges. Made from high-speed steel (HSS) and featuring 21 teeth per inch (TPI), the blades are intended for clean cutting of thin to medium-thickness metal sheets, profiles and pipes. The T-shank design provides secure attachment and broad compatibility with jigsaws that accept standard T-shank blades.

Advantages

These HSS jigsaw blades deliver a balance of hardness and toughness suitable for cutting steel and non-ferrous metals while maintaining a sharp edge for longer intervals compared with standard carbon blades. The 21 TPI tooth pitch supports fine, burr-reduced cuts and improved surface finish, reducing the need for post-cut filing. Supplied as a set of five, the package ensures replacement blades are available for multiple tasks or professional workflows.

Suitable for

• Cutting thin to medium-thickness steel sheets
• Trimming and shaping aluminium and other non-ferrous metals
• Cutting metal profiles and thin-walled pipes
• Applications requiring fine, clean edges and reduced burrs

Key specifications

• Blade type: T-shank for jigsaws
• Material: High-speed steel (HSS)
• Tooth count: 21 TPI (teeth per inch) for fine cutting
• Quantity: 5 blades per set
• Intended use: Metal cutting (steel and non-ferrous metals)

How to use

Install the T-shank blade into the jigsaw following the tool manufacturer's blade-change procedure, ensuring the blade is seated and locked securely. Select a moderate to slow cutting speed appropriate for the metal thickness to avoid overheating; for harder steels, use lubricant or cutting oil to extend blade life and improve cut quality. Support the workpiece firmly and feed the blade steadily without forcing to achieve a clean edge. Replace blades when wear or tooth damage affects cut quality.

Usage recommendations

For best results when cutting steel, use a lower jigsaw speed and apply cutting oil to reduce heat buildup. When working with aluminium and softer non-ferrous metals, higher feed rates are acceptable but avoid excessive vibration. Store blades dry and free from corrosive environments to maintain performance.
