The Yellow Square set contains seven flexible diamond polishing wheels, 100 mm in diameter, plus a backing pad with an M14 arbor. The discs attach by Velcro hook-and-loop and run from #50 to #3000 grit, so one kit takes granite, marble, concrete, porcelain stoneware, natural stone or tile from rough grinding to a mirror finish, working dry or wet.

What you get
- A complete grit ladder — seven pads from #50 to #3000 cover stock removal through final gloss.
- Tool-free pad swaps — Velcro hook-and-loop backs peel off and press on in seconds.
- Edges and curves, not just flats — the flexible 100 mm wheel bends to follow bevels and bullnoses.
- Diamond for hard stone — rated for granite, marble, concrete and porcelain stoneware.
- Dry or wet use — wet polishing is recommended for granite and porcelain stoneware.
- Backer included — M14 arbor, 14 mm, so the kit is ready to mount.
Who it is for
Tile setters and stone fabricators who finish cut edges on site, anyone restoring granite sills, marble steps or concrete surfaces, and DIY users with an angle grinder that has an M14 spindle.
Who should look elsewhere
If your tool does not take an M14 fitting, the included backer will not mount. These are polishing wheels, not cutting discs, so they will not slice through tile or stone.
Applications and compatibility
Grinding and polishing stone, concrete and tile from rough removal to a mirror finish; working granite, marble and porcelain stoneware; dry and wet sanding. Compatibility: angle grinder, backer arbor M14.
In the box
7 diamond discs (#50, #100, #200, #400, #800, #1500, #3000) and 1 backing pad (holder) with hook-and-loop face for M14.
Questions and answers
Do I need water?
No, the set supports dry polishing, but wet polishing is recommended for hard materials such as granite and porcelain stoneware.
Which pad goes first?
Start with #50 or #100 for chips and uneven spots, then step up through #200, #400 and #800, and finish with #1500 and #3000.
Will the backer fit my grinder?
The backer has an M14 arbor with a 14 mm diameter. Check that your grinder spindle matches before mounting.
Can I polish the edge of a tile?
Yes. The flexible wheel follows edges and bevels, which makes it practical for cleaning up a freshly cut tile edge.
