Creating a polygon grid from raster cell resolution...?

Is it possible to create a polygon grid based on the size of the cells within a raster layer?

All the cells are the same value and, when you use raster to polygon tool, you end up with a polygon of the raster extent, not the individual cells?

Am I goin agout this the wrong way...???

Basicaly, I want to grate a polygon grid with the following:
Cols and Rows: 21920,28160
Extent: Top=1223000, Left=-239000, Right=857000 and Botton=-185000
