Single Rhombus Diamond Tool — Tapered Edge, Big Cut

Built for aggressive surface prep and cleaner tracking. Tapered edge profile helps on Lavina, EDCO, Onfloor, and many off-brand plate setups that use the same style pattern (verify your plate style before ordering).

  • ✓More Coverage Per Pass

    Oversized rhombus layout covers more floor so you move faster and stop wasting steps.

  • ✓Diamond-Heavy Cut

    High diamond concentration for quick leveling and solid material removal when the floor fights back.

  • ✓Glue + Coating Killer

    Made to chew through adhesives, paint, coatings, and nasty build-up without babying the machine.

  • ✓Tapered Edge Advantage

    Better clearance and smoother transitions, less “hang up” at edges and uneven spots.

  • ✓Broad Compatibility

    Common fitment for Lavina, EDCO, Onfloor, and multiple aftermarket/off-brand grinders using the same plate pattern.

  • ✓Cost Per Sq Ft Friendly

    Designed to keep your cost down while still cutting hard. (Real-world results vary by slab + coatings.)
