The Weha 3.5” Turbo Disc is a rigid diamond polishing wheel engineered for flat surface repolishing, flat edge finishing, bevel work, and seam preparation on stone countertops. The extremely rigid construction eliminates flex and waves, producing a factory-level surface finish. Available in a full 7-step progressive grit sequence (50 through 3000) for complete edge and surface polishing from coarse stock removal to mirror finish.

Ideal for seam prep before lamination, repolishing scratched surfaces, and finishing flat edges, bevels, and mitres on granite, marble, quartz, and engineered stone. The compact 3.5” diameter reaches tight corners and seams where larger pads cannot.

SKU	Grit	Primary Use
TD350100	100	Seam prep, edge and bevel finishing

► Grit 200 — Medium, Surface Refinement

Grit 200 refines the surface left by the 100-grit disc, removing coarser scratch patterns. Especially important on sensitive materials like marble and quartzite where scratch visibility is higher.

SKU	Grit	Primary Use
TD350200	200	Scratch removal, surface refinement

► Grit 400 — Medium-Fine, Pre-Polish

Grit 400 removes the 200-grit scratch pattern and transitions the surface from matte to semi-gloss. Critical before fine polishing — consistency here determines final gloss quality on granite and quartz.

SKU	Grit	Primary Use
TD350400	400	Pre-polish, semi-gloss surface

► Grit 800 — Fine, Gloss Development

Grit 800 develops true gloss, producing a reflective sheen on granite and marble. The surface transitions from semi-gloss to high gloss at this stage. Ideal for honed marble finishes.

SKU	Grit	Primary Use
TD350800	800	Gloss development, high-gloss polish

► Grit 1500 — Extra Fine, High Gloss

Grit 1500 produces a high-gloss near-mirror finish on granite and quartz. The final disc before buffing on most materials — leaves the surface reflective and ready for optional polishing compound.

SKU	Grit	Primary Use
TD351500	1500	High gloss, near-mirror finish

► Grit 3000 — Ultra Fine, Mirror Polish

Grit 3000 is the finest in the series, delivering a true mirror polish on granite, quartz, and marble. Use as the final step for maximum gloss and clarity. Particularly stunning on dark granite and black quartz.
