Weha 5 in Flap Diamond Cup Wheel — Grit 400 for Stone Surface Prep
The Weha 5 in Flap Diamond Cup Wheel grit 400 combines diamond cup-wheel cutting power with a flap-disc pattern, producing a more consistent finish than a rigid cup wheel alone. Grit 400 places it in the medium-fine prep range — ideal for surfacing and pre-polish work on granite, marble, and engineered stone.

- Grit 400 — medium-fine surface prep

- Wear ANSI Z87 eye protection and a dust-rated respirator.
- Inspect the tool/accessory before each use; remove from service if cracks, deformation, or excessive wear are visible.
