Diamond cutting wheel Polax SEGMENT 125×7×2.1×22.23 mm for masonry and concrete

Diamond cutting wheel Polax SEGMENT 125×7×2.1×22.23 mm is made for cutting masonry, concrete and similar construction materials. The segmented rim design provides efficient debris clearance and faster cooling during continuous cutting. With a 125 mm diameter and 22.23 mm bore, the wheel fits standard angle grinders and compact handheld tools, while the 2.1 mm kerf balances cutting speed and material removal for controlled, precise cuts.

Advantages

The segmented diamond rim increases cutting performance on hard, abrasive substrates and reduces clogging. The narrow 2.1 mm kerf minimizes material waste and requires less cutting force, improving fuel efficiency of the machine and operator control. The 125 mm diameter enables access to tighter spaces and use with compact angle grinders. The standardized 22.23 mm bore ensures compatibility with common arbor sizes. Designed for a balance of durability and cutting speed on masonry and concrete.

Suitable for

• Cutting concrete blocks and reinforced concrete
• Trimming brick, block and stone elements
• On-site renovation and repair work
• Use with compact angle grinders and handheld cutting tools

Key specifications

• Diameter: 125 mm
• Segment height: 7 mm
• Kerf (blade thickness): 2.1 mm
• Bore (arbor) diameter: 22.23 mm
• Rim type: segmented diamond rim
• Primary application: masonry and concrete cutting

How to use

Install the wheel on a properly rated angle grinder or handheld cutter with a matching 22.23 mm arbor. Ensure the tool is powered off and disconnected from the power source before fitting. Tighten the mounting flange according to the tool manufacturer's instructions and verify the wheel is secure and runs true. During cutting, maintain steady, even feed pressure without forcing the blade; allow the diamond segments to cut at their designed rate. Use the appropriate RPM range for a 125 mm diamond wheel and avoid side loads or twisting motions that can damage the segments.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, hearing protection, gloves and a dust mask or respirator. Use water cooling if recommended by local regulations or when extended cutting causes excessive dust or heat; otherwise operate with regular intermittent cutting to allow cooling. Inspect the wheel for damage before each use and replace if segments are cracked or the bond is compromised. Follow the angle grinder manufacturer's safety guidelines and observe maximum RPM limits stamped on the wheel and tool.
