About the Lavina Quick Change Metal Bond Discs
These are the discs that let a floor crew change grit without a spanner: the three-pin quick change mount releases the disc in seconds, so a four-step sequence takes minutes rather than an afternoon. Four curved metal-bond segments do the grinding, and the 3 inch size matches the standard Lavina and compatible heads.
Typical applications
- Concrete floor grinding — First and intermediate steps before resin polishing on polished concrete jobs.
- Terrazzo and exposed aggregate — Grinding back to the aggregate without dishing the surface.
- Coating removal — Stripping epoxy and thin screeds with a walk-behind machine.
How to choose the right specification
- Grit sequence — 16# / 24# / 30# for cutting, 50#–100# for refining, 150#–400# before the resin pads take over.
- Mount type — Three-pin quick change for Lavina-type heads, bolt-on for machines with fixed plates — confirm before ordering.
- Segment count — Four segments run smoother and flatter than three on wide heads; ask which your machine's plate was designed for.
