Diamond Cutting Disc Makita B-55348 350 mm for Metal and Concrete

The Diamond Cutting Disc Makita B-55348 350 mm for Metal and Concrete is a segmented diamond blade engineered for cutting tasks in construction and metalworking environments. It features a continuous, diamond-impregnated rim with segmentation designed to balance cutting speed and cooling, enabling efficient removal of material from concrete, reinforced concrete, masonry and various metal components when used with compatible 350 mm power saws and cutting machines.

Advantages

This diamond cutting disc offers a longer service life compared with conventional abrasive discs due to the diamond cutting edge, delivering consistent cutting performance across repetitive tasks. The segmented rim improves debris clearance and reduces heat buildup, contributing to more stable cuts and less risk of glazing. Its 350 mm diameter provides a deep cutting capacity suitable for thicker materials, while the disc’s construction minimizes vibrations for safer, more controlled operation.

Suitable for

• Cutting concrete, reinforced concrete and masonry
• Cutting steel sections, pipes and metal profiles (with appropriate cutting technique)
• Use on compatible 350 mm power saws, wall saws and bridge saws
• Jobsite heavy-duty cutting and renovation tasks

Key specifications

• Diameter: 350 mm
• Cutting material: diamond-impregnated rim suitable for concrete and metal
• Segmented rim design for improved cooling and debris removal
• Typical mounting bore type: standard centre hole for 350 mm discs (verify machine compatibility)
• Intended use: wet or dry cutting depending on machine capability and safety guidelines

How to use

Install the disc on a compatible power saw following the machine manufacturer’s instructions and ensuring the disc is mounted with the rotation direction indicated. Tighten the fastening hardware to the specified torque and verify that guards and safety features are in place. Begin cutting at a steady feed rate appropriate to the material; avoid excessive force. For reinforced concrete and metal, maintain a controlled, steady motion to allow the diamond segments to cut efficiently. Observe recommended safety procedures including eye, hearing and respiratory protection and ensure the workpiece is securely fixed.

Usage recommendations

For prolonged disc life and safer performance, use water cooling when the machine supports wet cutting, or allow intermittent cutting pauses to reduce heat buildup during dry cutting. Always match the disc speed rating to the tool’s maximum RPM and replace the disc when diamond wear reduces cutting efficiency or segment integrity is compromised.
