Diamond Blade RUBI SEV 230 PRO Segment Dry, 230 mm, model 25916

The Diamond Blade RUBI SEV 230 PRO Segment Dry, 230 mm (model 25916) is a segmented diamond cutting disc developed for dry cutting of hard construction materials. Designed for use with angle grinders and portable cutters, the blade has a segmented rim geometry that promotes fast debris evacuation and stable cut control when working without water. It is intended for renovation, installation and on-site cutting tasks involving masonry, concrete, brick and similar dense substrates.

Advantages

The segmented design reduces friction and improves chip removal, allowing efficient dry cutting with less heat buildup. Industrial-grade diamond grit on the rim delivers consistent cutting performance and service life when used on hard materials. The disc is balanced for controlled operation on angle grinders and handheld cutters, which helps maintain straight cuts and reduces operator fatigue. Its 230 mm diameter provides a practical working depth for common construction tasks.

Suitable for

• Cutting reinforced and plain concrete blocks and panels
• Trimming and cutting clay or concrete brickwork
• On-site renovation cuts where wet methods are impractical
• Portable angle grinder or handheld cutter use for civil and building works

When it may not be suitable

This dry segmented blade is not intended for precision finish cutting where a very smooth edge is required; segmented rims can leave a rougher finish than continuous-rim blades. It is also not suitable for extended, uninterrupted cutting on extremely abrasive engineered materials without frequent pauses for cooling, as prolonged dry cutting increases wear.

Key specifications

• Diameter: 230 mm
• Cutting method: dry cutting
• Rim type: segmented diamond rim
• Compatible tools: angle grinders and portable cutters with matching arbor and speed ratings
• Typical applications: masonry, concrete, brick and similar hard construction materials

How to use

Fit the blade to a suitable angle grinder or portable cutter following the tool manufacturer’s instructions and ensure the arbor and flange match the disc. Securely tighten the mounting hardware and check that the blade runs true before use. When cutting, use controlled steady feed pressure and let the blade do the work; avoid forcing the disc. For dry cutting, make intermittent passes to limit heat build-up and allow brief cooling pauses. Always use appropriate personal protective equipment and dust suppression measures when possible.

What to consider before purchase

• Confirm compatibility with your tool’s arbor diameter and maximum RPM
• Consider the type of material you will cut and whether a segmented dry blade is appropriate
• Assess jobsite conditions for dust control and whether wet cutting would be preferable

Usage recommendations

Use the RUBI SEV 230 PRO with operator-rated angle grinders or portable cutters at the recommended speeds, make short controlled cuts to reduce overheating, and inspect the blade regularly for wear or damage. Combine with respiratory protection, eye protection, and dust containment to maintain safe working conditions.
