Grout scraper blade Makita HM 32 x 50 mm K40 for multi-tool B-65090

Replacement grout scraper blade Makita HM 32 x 50 mm K40 is a hard-metal (HM) accessory designed for use with compatible oscillating multi-tools. With a working width of 32 mm and a length of 50 mm, this blade features K40 grit for aggressive removal of grout, sealant and thin adhesive residues. It is intended for renovation and tile repair tasks where controlled, precise grout removal and surface preparation are required.

Advantages

The hard-metal construction ensures high wear resistance and durability during repetitive scraping and grinding operations. The K40 grit delivers an efficient cut rate on cement-based grout and hardened sealants while preserving the shape and stability of the blade. Its compact 32 x 50 mm size provides access to narrow joints and corners, allowing accurate removal without excessive material loss from surrounding tiles or substrates.

Suitable for

• Removing cement and epoxy grout from tile joints
• Stripping hardened sealant and thin adhesive layers
• Local surface preparation prior to regrouting or re-bonding
• Renovation and tile repair in bathrooms, kitchens and wet areas

Key specifications

• Blade material: hard metal (HM)
• Working width: 32 mm
• Blade length: 50 mm
• Abrasive grit: K40
• Compatibility: oscillating multi-tools with corresponding accessory mount

How to use

Install the grout scraper blade on a compatible oscillating multi-tool following the tool manufacturer's instructions and ensure the blade is securely fastened. Adjust oscillation speed to a moderate setting suitable for grout work and position the blade edge into the joint at a shallow angle. Apply controlled, steady pressure and move the blade along the joint to remove grout or sealant; avoid forcing the blade to reduce risk of damage to tile edges. Periodically inspect the blade for wear and replace when cutting performance diminishes.

Usage recommendations

Use appropriate personal protective equipment, including safety glasses, dust mask and gloves. For best results on deep or very hard grout, make multiple shallow passes rather than a single aggressive cut. Keep the work area ventilated and remove loose debris frequently to maintain visibility and reduce tool load.
