Diamond Cutting Disc Makita B-53986 115 mm for Concrete and Brick

Diamond cutting disc Makita B-53986 115 mm for Concrete and Brick is a thin, hard-wearing rotary cutting wheel engineered for use with angle grinders that accept 115 mm discs. It is designed to cut through concrete, brick and other masonry materials with a diamond-segment edge that delivers consistent cutting performance and extended abrasive life. The disc’s diameter and profile provide a balance between cutting speed and control for both through-cuts and detailed work on construction and renovation sites.

Advantages

The diamond-segment rim offers improved durability and maintains cutting speed over prolonged use, reducing the need for frequent disc changes. Its 115 mm size allows access to tighter spaces and makes the disc suitable for handheld angle grinders commonly used in building and renovation tasks. The shape and composition of the cutting edge ensure stable cuts in dense masonry while minimising chipping when used with proper technique and machine settings.

Suitable for

• Cutting concrete slabs and blocks
• Cutting clay and cement brick
• Making openings for pipes and utilities in masonry walls
• Detailed trim cuts near edges and corners
• Renovation and repair tasks on construction sites

Key specifications

• Diameter: 115 mm
• Primary material compatibility: concrete, brick and general masonry
• Cutting edge type: diamond-segment rim for abrasive durability
• Mounting: for angle grinders that accept 115 mm discs
• Typical usage: dry cutting; check tool specifications and local regulations for wet cutting capability

How to use

Fit the disc to a compatible 115 mm angle grinder following the grinder manufacturer’s instructions and ensure the power tool is disconnected from power while mounting. Secure the disc with the correct flange and tighten to the specified torque. Use appropriate rotation direction and a steady feed rate when cutting; avoid excessive force that can overheat the disc. Maintain a consistent cutting angle and allow the diamond segments to do the work, withdrawing the wheel periodically to clear debris and cool the cutting zone if performing extended cuts.

Usage recommendations

Always use personal protective equipment including eye protection, hearing protection, dust mask or respirator and cut-resistant gloves. Verify the angle grinder’s maximum RPM rating is compatible with the disc’s rated speed. For best results on dense or reinforced concrete, consider several shallow passes rather than attempting a single deep cut. Store the disc flat in a dry place and inspect for cracks or damage before use; do not use a damaged disc.
