Diamond Segmented Cutting Blade MEGA 115 mm, 1.9 x 6.8 mm segments, model 86515

MEGA diamond segmented cutting blade 115 mm, model 86515, is a circular cutting wheel designed for use with angle grinders on hard building materials. The blade features segmented diamond rim sections measuring 1.9 x 6.8 mm that provide efficient material removal, improved cooling and rapid debris clearance. It is intended for high-speed abrasive cutting of concrete, brick, masonry and similar substrates in construction and renovation tasks where a fast cutting action and durability are required.

Advantages

The segmented diamond design balances cutting speed and longevity by exposing diamond grit at each segment for continuous abrasive action while gaps between segments allow airflow to reduce heat buildup. The 115 mm diameter makes the blade compatible with common compact and handheld angle grinders, offering good control and access in confined spaces. The construction supports consistent cutting performance on hard materials and helps resist glazing and clogging during routine use.

Suitable for

• Cutting concrete blocks and panels
• Slicing through bricks and pavers
• Trimming masonry and mortar joints
• General material removal in renovation and construction

When it may not be suitable

This segmented blade is optimized for hard, abrasive building materials and may not be the best choice for precision wet cutting or for very thin, delicate materials that require a finer kerf. For tasks that demand the smoothest edge or kerf width control—such as detailed tile work or polished stone finishing—a continuous rim or turbo rim blade designed for wet cutting may be more appropriate.

Key specifications

• Diameter: 115 mm
• Segment dimensions: 1.9 x 6.8 mm
• Type: segmented diamond rim
• Designed application: dry high-speed abrasive cutting
• Compatible tool: handheld angle grinders (115 mm discs)

How to use

Mount the blade on an angle grinder compatible with 115 mm discs following the grinder manufacturer’s instructions and ensuring the spindle lock and flange are secure. Use appropriate personal protective equipment including eye protection, gloves, hearing protection and respiratory protection when cutting masonry materials. Operate the grinder at the recommended speed, apply steady, moderate pressure and allow the blade to do the cutting—avoid forcing the disc. Take periodic breaks during extended cutting to allow cooling and to clear dust and debris from the work area.

What to consider before purchase

• Ensure your angle grinder accepts 115 mm diameter blades
• Match the blade type (segmented diamond) to the material and dry cutting method
• Confirm required safety equipment and dust control measures for masonry cutting

Usage recommendations

For best results, use the blade for dry, high-speed cuts in concrete, brick and masonry, maintain a steady cutting speed, and allow cooling intervals during prolonged use. Replace the blade if segments show excessive wear or if cutting performance declines noticeably.
