Cutting Disc Makita B-55310 125 mm — diamond blade for metal and concrete

Diamond cutting disc Makita B-55310, 125 mm diameter, is designed for cutting tasks that combine metal and concrete. Intended for use with 125 mm angle grinders, this disc provides a compact cutting solution for job sites, workshops and renovation projects where different materials must be processed with a single tool.

Advantages

The cutting disc combines a diamond-edged rim suitable for abrasive building materials with a reinforced core that supports stable operation on hand-held angle grinders. Its 125 mm size offers a balance between portability and cut depth, while compatibility with standard 125 mm grinders ensures straightforward replacement and mounting. The disc is designed for mixed-material use, allowing technicians to switch between cutting metal components and concrete without changing discs frequently.

Подходит для

• резка металлических труб и профилей
• резка бетонных блоков и плит
• работы по ремонту и реконструкции строительных конструкций
• слесарные и монтажные операции в мастерских

Key specifications

• Diameter: 125 mm
• Intended material: metal and concrete
• Mounting: for 125 mm angle grinders
• Cut type: abrasive/diamond rim for mixed-material cutting
• Typical cut depth: suitable for shallow to medium-depth cuts with 125 mm discs

How to use

Install the disc on a 125 mm angle grinder following the grinder manufacturer's instructions, ensuring the disc's rotation direction matches the arrow on the disc. Secure the disc with the correct flange and tighten to the recommended torque. When cutting, position the grinder so the disc enters the material at a steady, controlled speed; avoid excessive pressure and allow the disc to do the cutting. Use multiple shallow passes for thicker sections rather than forcing a single deep cut. Inspect the disc before use for damage or wear and replace it if any cracks or severe wear are present.

Usage recommendations

Use appropriate personal protective equipment — eye protection, hearing protection, gloves and respiratory protection if cutting generates dust. For best performance when cutting metal, ensure workpieces are clamped and free of loose coatings; when cutting concrete, control dust with wet cutting or a dust-extraction system where practical. Do not use the disc on materials outside its intended scope and stop immediately if vibration or unusual noise occurs.
