• Blade width: 32 mm
• Attachment type: multifunction/oscillating tool blade
• Compatibility: for use with compatible Makita multifunction tools
• Purpose: general-purpose cutting and detail operations

How to use

Before installation, ensure the multifunction tool is switched off and disconnected from power or battery. Fit the blade to the tool following the tool manufacturer’s instructions, making sure it is properly seated and securely fastened. Select the correct oscillation speed and apply steady, controlled pressure while cutting; allow the blade to do the work rather than forcing it. For plunge cuts, position the tip at the start point and engage the tool gradually to achieve a clean entry. After use, remove the blade carefully and store it in a dry place.

Usage recommendations

Use this 80 mm x 32 mm Makita-compatible blade for precision trimming, light demolition, and controlled plunge cuts. Match blade type and oscillation speed to the material: lower speeds for plastics and drywall, moderate speeds for wood and composites. Replace the blade when cutting performance degrades or if damage to the cutting edge is visible. Always follow safety guidelines for personal protective equipment and the multifunction tool manufacturer’s instructions.
