Diamond Grinding Discs for Lavina and Edco Magnatrap Grinders - Set

In this review the author tests a set of three diamond grinding discs designed for Lavina, Onfloor and EDCO Magnatrap grinders and finds them suited to contractors and serious DIYers who need reliable mid-stage concrete grinding. The single biggest reason to buy is consistent cutting performance on medium hard to hard concrete thanks to the soft bond formulation paired with densely packed diamond button segments. Fitment is straightforward for the named machines and customers will appreciate that the discs focus on performance rather than decorative finish.

Key Features

• Double Segments: Diamond encrusted button segments deliver steady material removal and maintain cutting edges over extended passes.
• Soft Bond: The bond hardness is formulated to expose diamonds appropriately when working medium hard to hard concrete for efficient grinding.
• Grit Size 120/150: The dual grit provides a mid-level abrasive suited for smoothing and preparing concrete before finer polishing stages.
• Set of 3: Including three discs gives immediate replacement options on a job or allows for staged wear without frequent reordering.
• Compatibility: Designed to fit Lavina, Onfloor and EDCO Magnatrap style grinders so swapping is quick and simple for those machines.

Who It's For

The discs are best for professional concrete contractors and experienced DIYers who run Lavina, Onfloor or EDCO Magnatrap grinders and need dependable mid-grit tooling for surface preparation and moderate stock removal. They suit jobs where the operator expects predictable wear and consistent diamond exposure on medium hard to hard substrates.

Those seeking very fine polishing discs or tools for soft, delicate concrete surfaces should look elsewhere, as the 120/150 grit and soft bond are optimized for more aggressive surface preparation rather than final mirror finishes.

Pros & Cons

Pros

• Work well in field conditions and provide steady cutting action across concrete surfaces.
• Diamond quality is praised by users, indicating durable segments and reliable performance.
• Compatibility with common grinder platforms reduces downtime for machine-specific users.

Cons

• Grit range is mid-level so these are not intended for final polishing or ultra-fine finish steps.
