Jigsaw/Scroll Saw/Reciprocating Saw Blade Irwin 10504232 — for Metal and Wood

Irwin 10504232 replacement blades are bi-metal cutting blades designed for use with jigsaws, scroll saws and compatible reciprocating saws. Supplied as a T-shank 5-piece pack, these blades combine a progressive tooth form and bi-metal construction to handle a range of common ferrous and non-ferrous metals as well as soft and hard woods. The blades are intended for renovation, workshop and construction tasks where both straight and curved cuts are required.

Advantages

The bi-metal construction pairs high-speed steel cutting edges with a flexible alloy back for improved durability and resistance to breakage. Progressive tooth geometry provides a balance between fast material removal and smooth finish, allowing the same blade to cut both metal and wood without frequent blade changes. The T-shank design ensures simple and secure mounting in most modern jigsaws and scroll saws, while the multi-pack supply reduces downtime by providing spares for repeated or extended jobs.

Suitable for

• Cutting thin to medium-gauge steel and non-ferrous metals
• Cutting softwoods, hardwoods and plywood
• General renovation and workshop cutting tasks
• Making straight and curved/profile cuts in mixed-material projects

Key specifications

• Blade type: Bi-metal with progressive tooth form
• Shank type: T-shank for quick tool compatibility
• Pack quantity: 5 blades per pack
• Intended materials: Ferrous and non-ferrous metals, soft and hard woods
• Cutting style: Suitable for straight and curved cuts

How to use

Install the T-shank blade into the tool according to the tool manufacturer’s instructions, ensuring the blade is seated and tightened securely before operation. Select an appropriate speed and feed rate for the material: slower speeds and steady feed for metals, higher speeds and moderate feed for wood. Use steady, controlled motion and support the workpiece to reduce vibration and improve cut accuracy. Replace blades when wear or tooth damage reduces cutting performance.

Usage recommendations

For best results, clamp the workpiece, use appropriate personal protective equipment (eye and hearing protection, gloves where applicable), and let the blade do the cutting without excessive side pressure. Match cutting speed to the material and replace blades showing wear to maintain cutting quality and tool safety.
