Diamond cutting blade Flex DISTAR DIAMOND CROWN RM-TX 1 1/4" 300mm x 450mm DRY

Diamond cutting blade Flex DISTAR DIAMOND CROWN RM-TX 1 1/4" 300mm x 450mm DRY is a professional dry-cut blade engineered for high-speed cutting of concrete, masonry and similar hard materials. The blade has a 1 1/4" bore and overall dimensions of 300 mm x 450 mm, designed to fit saws that accept this arbor size. It is intended for on-site use where wet cutting is impractical and where durability and sustained cutting performance are required in construction and renovation tasks.

Advantages

This dry diamond blade delivers efficient material removal and stable cutting performance on dense substrates such as reinforced concrete and masonry. The segmented diamond crown design reduces friction and heat build-up during high-speed dry operation, while the construction provides consistent blade life under heavy-duty use. Compatibility with common 1 1/4" arbors makes it suitable for many professional saws used on job sites.

Suitable for

• High-speed dry cutting of reinforced concrete
• Masonry blocks, bricks and similar building materials
• On-site construction and renovation cutting tasks
• Saws and grinders that accept a 1 1/4" arbor and 300 mm x 450 mm blade

When it may not be suitable

The blade is specifically designed for dry cutting; it may not be suitable where wet cutting is required to control dust or where water cooling is necessary to prevent overheating for extended continuous cuts. It is not intended for precision finishing cuts on delicate or thin materials that require minimal chipping.

Key specifications

• Cutting method: Dry
• Blade dimensions: 300 mm x 450 mm
• Bore size: 1 1/4" (arbor)
• Application materials: Concrete, reinforced concrete, masonry
• Design: Segmented diamond crown for heat dissipation and chip clearance

How to use

Install the blade on a compatible saw with the correct 1 1/4" arbor fitting, following the saw manufacturer's mounting and safety instructions. Ensure the blade rotation direction matches the saw's arrow marking. Secure the workpiece and use steady feed pressure without forcing the blade; allow the diamond segments to cut at rated speed. Monitor blade temperature and allow cooling pauses during prolonged use to reduce overheating. Always wear appropriate personal protective equipment including eye, ear and dust protection when operating a dry cutting blade.

What to consider before purchase

• Confirm your saw accepts a 1 1/4" arbor and the blade's 300 mm x 450 mm dimensions.
• Assess whether dry cutting is acceptable for your job site considering dust control and local regulations.
• Consider the material types to be cut (concrete, masonry) and cutting speed requirements.

Usage recommendations

For best results, use the blade on saws rated for high-speed dry cutting, perform intermittent cutting to manage heat buildup, and maintain proper blade alignment and feed rate. Replace the blade when cutting performance or segment wear noticeably decreases.
