Plunge saw blade Makita B-64951 / B-64945-5, 20 mm, carbide (HM), STARLOCK, set of 5

This replacement plunge saw blade set is designed for oscillating multi-tools and intended for precise plunge cuts in metal and similar hard materials. Each blade is 20 mm wide and manufactured with carbide (HM) teeth to maintain cutting performance and wear resistance during demanding metal cutting tasks. The STARLOCK interface enables quick, secure attachment and stable operation when used with compatible tool holders. The set contains five identical blades, allowing multiple replacements or extended use without immediate repurchase.

Advantages

Carbide (HM) construction provides long-lasting edge retention and improves durability compared with high-speed steel blades when cutting abrasive or hardened materials. The 20 mm cutting width offers controlled, narrow plunge cuts and good access in confined or detailed work areas. The STARLOCK mounting system ensures fast, tool-free blade changes and consistent alignment with compatible oscillating tools, reducing setup time and vibration transfer during operation.

Suitable for

• Plunge cutting thin metal sheets and non-ferrous metals
• Removing rusted or welded spots and localized metal repair
• Cutting metal profiles, pipes with thin walls, and fastening materials
• Precision trimming and detail work in metalwork and fabrication

Key specifications

• Blade width: 20 mm
• Tooth material: carbide (HM)
• Mount type: STARLOCK interface for oscillating multi-tools
• Pack contents: 5 identical plunge saw blades

How to use

Secure the oscillating multi-tool in accordance with the tool manufacturer’s instructions and ensure the device is powered off before changing blades. Align the STARLOCK connection on the blade with the tool’s mounting interface and press into place until it locks. Position the blade at the intended plunge location and start the tool at a moderate speed to establish the cut, applying steady, controlled pressure; avoid forcing the blade. For metal cutting, use cutting oil or cooling as appropriate to reduce heat and prolong blade life. After use, allow the blade to cool before removing or storing.

Usage recommendations

The blades are intended for intermittent plunge cuts in metal and similar materials; select an oscillating tool speed suited to the metal thickness and apply light, consistent feed. Replace blades when cutting performance declines or if teeth show significant wear. Store the blades in a dry place and avoid impacts that could chip the carbide teeth.
