Diamond saw blade Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" (42 mm) x 450 mm DRY

Circular diamond saw blade Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" (42 mm) x 450 mm DRY is a high-speed dry-cutting blade designed for demanding construction and renovation tasks. The blade features diamond segments arranged to provide stable cutting performance on hard mineral materials. Its 42 mm bore and 450 mm diameter match ring-mounted machines and compatible high-speed saws, allowing precise, fast cuts without coolant.

Advantages

The construction of the diamond segments and the blade body provide long service life and consistent cutting speed when used for dry cutting of stone and concrete. The RS-TX geometry is engineered to reduce vibration and improve edge stability, which supports accurate straight cuts. The blade's design minimises thermal damage during dry operation and enables efficient chip removal to maintain cutting performance over extended use.

Suitable for

• Cutting natural stone such as granite and marble
• Cutting concrete and reinforced concrete (with appropriate technique)
• Dry cutting on construction sites where water cooling is impractical
• Use with ring-mounted machines and high-speed handheld or bench saws compatible with a 42 mm bore

Key specifications

• Blade diameter: 450 mm
• Bore diameter: 42 mm (1 1/4")
• Suitability: dry cutting
• Segment type: diamond segments for cutting hard mineral materials
• Typical applications: stone, concrete, masonry materials

How to use

Install the blade on a compatible saw with a 42 mm arbor, ensuring correct orientation and secure mounting according to the machine manufacturer's instructions. Use the blade for dry cutting, maintaining steady feed rates and avoiding excessive lateral pressure. Allow the blade to run at the recommended operating speed for the machine and give periodic pauses on prolonged cuts to reduce heat buildup. Wear appropriate PPE including eye and respiratory protection due to dust generated during dry cutting.

Usage recommendations

For best results, match cutting speed and feed to the material hardness and thickness, use appropriate dust extraction or local ventilation, and follow the saw and blade manufacturer's safety guidelines. Inspect the blade before use for damage and replace if segments are worn or the blade shows visible defects.
