Multitool blade Makita B-65109 (TMA077) 32 mm conical HM scraper/grinding, grit 100, STARLOCK, for brick and glass-fiber materials

Replacement multitool blade Makita B-65109 (TMA077) is a 32 mm conical carbide (HM) scraper/grinding accessory with grit 100 and STARLOCK mount. Designed for grinding and scraping on masonry and glass-fiber materials, this blade fits oscillating tools equipped with the STARLOCK interface. It is intended for preparatory and repair work such as removing mortar, leveling brick surfaces and cleaning fibreglass mesh, offering a compact shape for access to narrow joints and uneven areas.

Advantages

The conical 32 mm carbide construction provides wear resistance and consistent abrasive performance at grit 100 for material removal and surface preparation. The STARLOCK mounting system ensures quick, secure blade changes and optimal power transmission between the oscillating tool and the accessory. Compact dimensions and the scraper/grinding profile enable controlled scraping and precise grinding in confined or irregular spaces.

Suitable for

• Removing mortar and old grout from brick joints
• Leveling and preparing brick or masonry surfaces
• Cleaning and abrading glass-fibre mesh or reinforced composites
• Detail scraping and trimming in renovation and repair tasks

Key specifications

• Blade shape: conical scraper/grinding profile
• Working width: 32 mm
• Abrasive material: carbide (HM) with grit 100
• Mount type: STARLOCK interface for oscillating tools
• Primary materials: suitable for masonry (brick) and glass-fibre materials

How to use

Attach the Makita B-65109 blade to a compatible STARLOCK-capable oscillating tool following the tool manufacturer's instructions and ensure the tool is switched off and disconnected from power before fitting. Position the conical blade at a shallow angle and start with a low oscillation speed to gauge material removal; increase speed as needed for faster abrasion. Use controlled, steady strokes along the work area, allowing the carbide abrasive to remove mortar, level brick surfaces or clean fibreglass mesh without applying excessive pressure that could damage the substrate or wear the blade unevenly.

Usage recommendations

Wear appropriate personal protective equipment such as safety glasses, dust mask and gloves when grinding or scraping masonry and glass-fibre materials. For best results, inspect the blade periodically for wear and replace when abrasive performance diminishes. Use dust extraction or local ventilation to limit airborne particles when working with mortar and fibreglass debris.
