Jigsaw blade STANLEY STA25042 Bimetal 72 mm working length, 3 mm tooth spacing, for aluminium and metal, 2 pcs

STANLEY STA25042 bimetal jigsaw blades, pack of 2, are designed for cutting aluminium and other metals with hand-held jigsaws. Each blade provides a 72 mm working length and 100 mm overall length with 3 mm tooth spacing, enabling controlled cutting of sheet materials and thin metal profiles. The blades are supplied in blister packaging and are intended for metalworking tasks where a balance of durability and cutting precision is required. Maximum recommended cutting thickness is up to 30 mm when using appropriate machine settings and steady feed.

Advantages

Bimetal construction combines flexibility and wear resistance to reduce breakage during plunge cuts and curved cuts in metal sheets. The 3 mm tooth pitch is matched for efficient chip clearance and smoother cutting of aluminium and similar non-ferrous metals. Standard overall length and common shank design ensure compatibility with most jigsaw models that accept T-shank/jigsaw blades. Supplied as a two-piece set, the blades offer quick replacement and continued workflow for metal trimming and sheet cutting tasks.

Suitable for

• Cutting aluminium sheets and profiles
• Trimming and modifying thin steel or non-ferrous metal panels
• Workshop tasks requiring small straight or curved cuts in metal
• On-site metal repair and maintenance work with a portable jigsaw

How to use

Install the blade into the jigsaw according to the tool manufacturer's instructions, ensuring the blade is securely locked and the teeth face the correct cutting direction. Select appropriate speed and feed for the metal type—slower speeds and steady feed help control heat and reduce burr formation when cutting aluminium. Use cutting lubricant or coolant where applicable to improve blade life and achieve cleaner cuts. Replace blades when they show signs of dulling or excessive wear to maintain cutting efficiency and safety.

Usage recommendations

For best results when cutting aluminium and thinner metal sheets, use a firm clamping arrangement to prevent vibration, moderate jigsaw speed, and light steady pressure. Apply cutting fluid for longer blade life and smoother edges. Check blade condition regularly and change blades in sets to maintain consistent cut quality.
