Diamond crown saw blade Flex DISTAR RM-TX 92 mm x 450 mm with a 1 1/4" bore is a segmented diamond wheel designed for dry cutting of hard building materials. It is intended for use on compatible circular saws and masonry cutters to perform precise profiling, trimming and cutting operations on tiles, stone, concrete and similar dense materials where cooling with water is not possible or desired.
Advantages
The blade features a segmented diamond rim that provides fast cutting speed and effective debris removal during dry operation. Its construction balances cutting performance and segment durability to deliver consistent edge wear and predictable cutting results. The standard 1 1/4" bore ensures compatibility with many professional handheld saws and machines, while the 92 mm segment height and 450 mm overall diameter offer a combination of depth and stability for profile and trimming tasks.
Suitable for
- Dry cutting and profiling of ceramic and porcelain tiles
- Trimming and shaping natural and engineered stone
- Cutting and chamfering edges on concrete and dense masonry
- Use on compatible handheld circular saws and masonry cutters
When it may not be suitable
This diamond crown blade is optimized for dry cutting and may not perform as intended in continuous wet cutting applications; using it with water could reduce cutting efficiency and accelerate damage to the blade. It is not intended for cutting soft metals, timber, or general-purpose materials where a non-diamond blade is more appropriate.
Key specifications
- Overall diameter: 450 mm
- Segment height / working rim: 92 mm
- Bore diameter: 1 1/4" (compatible with 1 1/4" arbors and adapters)
- Intended cutting type: dry cutting
- Typical applications: tiles, stone, concrete, dense masonry
How to use
Mount the diamond crown blade on a compatible circular saw or masonry cutter with the correct bore adapter and secure it according to the machine manufacturer’s instructions. Operate the saw at the recommended RPM range for the blade and material, apply steady feed pressure without forcing the blade, and allow the diamond segments to cut at their designed pace. For safety and best results, use appropriate personal protective equipment including eye, hearing and respiratory protection, and ensure the workpiece is properly supported and clamped to avoid vibration.
What to consider before purchase
- Verify machine compatibility with a 1 1/4" bore and the saw’s maximum allowable blade diameter and RPM.
- Confirm the blade is specified for dry cutting and suitable for the materials you plan to work with (tiles, stone, concrete).
- Assess whether segmented diamond rims meet your precision and finish requirements compared with continuous rim blades.
Usage recommendations
For optimal life and cutting quality, use intermittent cutting passes rather than continuous prolonged cuts, avoid excessive lateral force, and keep the blade free of debris buildup. Match the blade speed to the material hardness and follow the equipment manufacturer’s safety and operating instructions.
