Diamond Grinding Discs for Lavina & EDCO Magnatrap Grinders - Extra

In this review of the Diamond Grinding Discs for Lavina and EDCO Magnatrap grinders the bottom line is clear: these discs are aimed at contractors and concrete pros who need aggressive cap cutting on very hard concrete and expect long life from diamondencrusted segments. The reviewer found the set of three discs to deliver fast material removal thanks to the double segments and a specially formulated extra soft bond that exposes diamonds quickly on hard surfaces, so they are especially useful when local supply shop options failed to cut effectively.

Key Features

• Double Segments: Diamond encrusted button segments increase cutting surface and maintain consistent contact for efficient grinding on tough concrete.
• Extra Soft Bond: The premium extra soft bond is designed to wear faster to expose fresh diamonds, making it suitable for grinding extremely hard concrete when cap cutting is required.
• 18/20 Grit Size: The coarse #18/20 grit provides aggressive material removal to speed up cap cutting and heavy stock removal tasks.
• Set of 3: Includes three discs so users can complete a job with spares on hand or rotate discs to maintain performance throughout a project.
• Machine Compatibility: Fits Lavina, Onfloor and EDCO Magnatrap style grinders, allowing these discs to be used on common professional grinding platforms.

Who It's For

The discs are best for professional concrete contractors, flooring installers and rental shops that regularly handle very hard concrete and need a coarse, aggressive disc for cap cutting and heavy grinding. Users who require fast stock removal and predictable wear will appreciate the combination of double segments and an extra soft bond.

These discs are not aimed at fine polishing jobs or decorative concrete work; hobbyists seeking smooth finishes or very fine grits should look for medium to fine grit tooling instead. Also, verify fitting compatibility with your specific grinder model before purchasing.
