Jigsaw/Scroll/Reciprocating Saw Blades Makita B-20454, Bimetal, 80 mm, 5 pcs

Makita B-20454 is a set of five bimetal saw blades designed for jigsaws, scroll saws and reciprocating saws. Each blade has an 80 mm working length and a bimetal construction that combines flexibility with a wear-resistant cutting edge. The blades are intended for mixed workshop use where users need to cut metal and wood, including wood with embedded nails, and to replace worn or damaged blades quickly during repair, demolition or maintenance tasks.

Advantages

The bimetal design provides improved edge life and resistance to breakage compared with standard carbon-steel blades. Uniform tooth geometry and hard-wearing cutting material maintain cutting performance across different materials. The compact 80 mm working length allows use in tight spaces and fast blade changes reduce downtime. A pack of five blades ensures a supply of replacements for multiple tasks without frequent reordering.

Suitable for

• Cutting thin metal sheets and profiles
• Cutting wood and wood with nails
• Repair and demolition work in confined areas
• General workshop and maintenance tasks requiring reciprocating or orbital cutting

Key specifications

• Blade type: bimetal construction for toughness and wear resistance
• Working length: 80 mm
• Pack quantity: 5 blades
• Compatible tool types: jigsaw, scroll saw, reciprocating saw
• Material applications: metal and wood (including wood with nails)

How to use

Select a blade from the pack appropriate for the material to be cut and install it according to the jigsaw, scroll saw or reciprocating saw manufacturer's blade mounting instructions. Ensure the tool is powered off and the blade clamp is secure before use. Start cutting at a moderate feed rate, allowing the bimetal tooth edge to make the cut without excessive pressure. For metal cutting, use steady motion and, if required, periodic cooling or lubricant designed for metalworking. Replace blades when cutting performance declines or teeth are visibly worn.

Usage recommendations

Use personal protective equipment, such as eye protection and gloves, and secure the workpiece before starting. For prolonged metal cutting, consider lower speed settings and intermittent cutting to extend blade life. Store unused blades in a dry place to prevent corrosion.
