Diamond cutting disc Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" (62 mm) x 450 mm, dry

Diamond cutting disc Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" (62 mm) x 450 mm, dry is a segmented diamond blade designed for high-performance dry cutting of hard construction materials. The disc combines a large 450 mm cutting diameter with a 1 1/4" (62 mm) bore to fit compatible handheld and machine-mounted cutting equipment. Its segmented rim and reinforced bond provide stable, accurate cuts through concrete, natural stone and similar dense materials while reducing heat buildup during dry operation.

Advantages

The segmented diamond crown offers fast material removal and long life under intensive use. Its dry cutting configuration eliminates the need for water supply and minimizes downtime on sites where wet cutting is impractical. The construction of the blade maintains cutting precision and reduces chipping on brittle stone surfaces, while reinforced segments improve resistance to wear when used on reinforced concrete and abrasive aggregates.

Suitable for

• Dry cutting of concrete slabs and reinforced concrete
• Cutting natural stone such as granite and limestone
• Structural demolition where handheld or machine-mounted cutters are used
• On-site cutting tasks without water supply or wet cutting systems

Key specifications

• Cutting diameter: 450 mm
• Bore (arbor) diameter: 1 1/4" (62 mm)
• Blade type: segmented diamond rim for dry cutting
• Designed use: hard, dense construction materials (concrete, stone)
• Compatibility: handheld and machine-mounted cutting equipment with matching arbor

How to use

Install the disc onto a cutter or saw ensuring the arbor size matches the 1 1/4" (62 mm) bore and that the blade is mounted in the correct rotation direction. Use appropriate guards and follow the equipment manufacturer's instructions for torque and fastening. When cutting, apply steady pressure without forcing the blade; allow the diamond segments to do the work. Monitor the tool for vibration or abnormal noise and stop immediately if any problems are detected.

Usage recommendations

Always use personal protective equipment including eye, ear and respiratory protection when performing dry cutting. Ensure adequate ventilation and avoid prolonged exposure to dust; consider using a dust extraction system if available. Match cutting speed and feed rate to the material to maximize blade life and maintain cutting accuracy.
