Diamond Cutting Disc Makita D-80070 115 mm diameter, 22.23 mm bore

Makita D-80070 is a 115 mm diamond cutting disc with a 22.23 mm bore designed for use with compact angle grinders. It is intended for precise wet or dry cutting of hard materials such as ceramic tile, natural stone and concrete. The segmented continuous rim and diamond bond construction provide consistent edge quality, controlled dust generation and extended life under typical renovation and construction workloads.

Advantages

The disc offers high cutting efficiency on brittle and dense materials while maintaining a slim kerf for fast progress and minimal material loss. Its balanced design reduces vibration for improved user control at high rotational speeds. Durable diamond grit and an engineered bond extend blade life, reducing frequency of replacements during repetitive cutting tasks.

Suitable for

• Cutting ceramic and porcelain tiles
• Trimming and shaping natural stone and marble
• Cutting concrete, mortar and masonry
• Small renovation and remodeling jobs with an angle grinder

How to use

Mount the disc on a compatible angle grinder with a 22.23 mm spindle or appropriate adapter, following the tool manufacturer's instructions and ensuring the disc is properly tightened. Confirm the disc rotation direction matches the grinder arrow. For dry cutting, use steady, moderate feed pressure and allow the blade to do the work to avoid overheating. For improved life and reduced dust, use water cooling where applicable and safe. Always inspect the disc before use for cracks or damage and replace if any defects are present.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and respiratory protection when cutting. Secure the workpiece, maintain stable footing and follow angle grinder safety guidelines. Match cutting speed and feed to the material hardness; reduce pressure on hard, brittle materials to avoid chipping. Store the disc flat in a dry environment away from extreme temperatures to preserve bond integrity.
