Diamond Cutting Disc Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" 52mm x 450mm DRY

The Diamond Cutting Disc Flex DISTAR DIAMOND CROWN RS-TX 1 1/4" 52mm x 450mm DRY is a dry-use diamond blade designed for precision cutting of dense building materials. With a 450 mm diameter and a 52 mm (1 1/4") bore, this disc is manufactured for use on compatible high-power saws and grinders intended for dry operation. Its construction prioritizes diamond segment performance and extended service life, enabling consistent cutting quality in masonry, concrete and natural stone where a durable cutting edge is required.

Advantages

The blade combines a high concentration of industrial diamond grit and a wear-resistant bond to provide steady cutting speed and long life when used dry. Its segment geometry and bonding process reduce chipping and improve edge stability during through-cuts. The 52 mm bore ensures firm mounting on standard arbors for compatible machines, maintaining concentricity and vibration reduction for accurate cuts. Designed for professional use, the disc maintains performance across repeated cuts in abrasive materials.

Suitable for

• Cutting reinforced concrete and structural concrete elements
• Masonry block and brick cutting
• Natural and artificial stone profiling and slicing
• Dry on-site cutting where water cooling is not available

Key specifications

• Diameter: 450 mm
• Bore (arbor) diameter: 52 mm (1 1/4")
• Operation mode: Dry cutting
• Intended materials: Concrete, reinforced concrete, masonry, natural and engineered stone
• Segment type: Crown/continuous segments optimized for reduced chipping

How to use

Mount the disc on a compatible saw or grinder with a 52 mm arbor, ensuring the machine is rated for a 450 mm blade and for dry cutting operation. Check that the blade rotates in the indicated direction and fasten according to the machine manufacturer’s torque specifications. Operate the saw at steady feed rates appropriate for the material hardness, avoiding excessive lateral pressure. Allow the blade to cool between long cutting runs to prevent overheating; follow the machine’s safety guidelines including guards, appropriate PPE and dust control measures.

Usage recommendations

For best results, use on machines with adequate motor power and stable mounts, keep cutting speed consistent, and avoid prolonged continuous cutting without short pauses to reduce thermal stress. Employ effective dust extraction when possible and inspect the blade before each use for wear or damage.
