Angle grinder accessory Proline 89230 — diamond segmented blade, 230 mm diameter

Proline 89230 is a diamond segmented blade for angle grinders with a 230 mm diameter. Designed for cutting and roughing work on concrete, masonry and natural stone, the segmented rim helps evacuate debris and improves cooling during extended construction and renovation tasks. The blade is supplied as a single unit and fits grinders that accept 230 mm discs.

Advantages

The segmented diamond rim provides faster cutting in hard materials and better chip clearance compared with continuous-rim blades. Laser-welded construction increases segment durability and attachment strength. A 230 mm diameter offers a balance between cutting depth and maneuverability for common construction applications.

Suitable for

• Cutting concrete slabs and blocks
• Trimming and cutting masonry, brick and blockwork
• Working with natural stone and granite for construction tasks
• General renovation and demolition where segmented blades are preferred

When it may not be suitable

The blade is optimized for hard mineral materials; it is not ideal for precision wet cutting of ceramic tiles or porcelain where a continuous rim blade provides a cleaner finish. For frequent asphalt cutting or reinforced concrete with heavy rebar, consider blades specifically formulated for those materials.

Key specifications

• Diameter: 230 mm
• Arbor diameter: fits standard 230 mm angle grinders (25.4 mm opening)
• Blade type: diamond segmented rim
• Construction: laser welded segments
• Intended materials: concrete, masonry, stone, granite (optional use on clinker, tiles, gres tiles, reinforced concrete, asphalt)

How to use

Mount the blade on a compatible 230 mm angle grinder with the correct arbor size and ensure the guard is fitted. Use appropriate personal protective equipment including eye, ear and respiratory protection. For best results, operate at the grinder's recommended RPM and make steady passes without forcing the blade; allow the cutting segments to do the work. If cutting dry, work in short intervals to avoid overheating; when possible and suitable for the material, use controlled water cooling following the grinder manufacturer's guidance.

What to consider before purchase

• Confirm your angle grinder accepts 230 mm blades and the arbor opening matches 25.4 mm.
• Choose a segmented diamond blade when working mainly with concrete, masonry or stone.
• For tile or porcelain work requiring a smooth edge, consider a continuous-rim blade instead.

Usage recommendations

Use the blade for dry or semi-wet cutting in construction and renovation tasks, take breaks to prevent overheating, and match blade type to material for optimal life and cutting quality.
