Diamond blade Flex DISTAR DIAMOND CROWN RM-TX 1 1/4" (42 mm) x 300 mm, dry cutting

Diamond blade Flex DISTAR DIAMOND CROWN RM-TX 1 1/4" (42 mm) x 300 mm is a segmented diamond cutting wheel engineered for dry cutting applications. Compatible with high-speed rotary saws and cutting machines that accept a 42 mm arbor, this blade is intended for working with hard construction materials where diamond segments deliver wear resistance and steady cutting performance. The 300 mm diameter provides a balance between cutting depth and machine compatibility, enabling precise straight cuts in renovation and building tasks.

Advantages

The diamond segments are designed to maintain cutting speed and extend service life under dry conditions, reducing the need for frequent blade changes. A 42 mm arbour hole ensures secure mounting on machines that support this standard, while the 300 mm diameter offers sufficient cutting depth for common construction operations. The segmented rim design improves debris removal and helps control heat buildup during continuous dry cutting.

Suitable for

• Dry cutting of reinforced concrete and concrete elements
• Cutting of masonry, brick and block materials
• Renovation and demolition where dry, fast cuts are required
• Work with high-speed rotary saws and stationary cutting machines with 42 mm arbor

Key specifications

• Diameter: 300 mm
• Arbor/hole size: 1 1/4" (42 mm)
• Cut type: dry cutting
• Rim style: segmented diamond rim
• Intended materials: concrete, reinforced concrete, masonry, brick

How to use

Mount the blade securely on a compatible saw with a 42 mm arbor following the machine manufacturer's mounting instructions. Check that the blade rotation direction matches the arrow on the blade and that all guards are correctly positioned. Operate the tool at the recommended speed range and feed rate for the material being cut; avoid excessive side pressure. Because this blade is designed for dry cutting, monitor the blade and workpiece temperature and allow cooling pauses during long cuts to prevent overheating.

Usage recommendations

Use appropriate personal protective equipment (eye protection, hearing protection, dust mask) and ensure adequate dust extraction or local ventilation when cutting. Inspect the blade before each use for signs of damage or wear and replace when segments are worn below recommended depth or when cracks are present.
