Grinding Discs

Precision Shaped Grain

Our Flamethrower Delta® Grinding Discs come in a diverse range of grits - from the aggressive 36 Grit for fast material removal to the finer 80 Grit for a smooth, finished surface. Each disc is crafted with precision-shaped grain technology, ensuring not only longevity but also consistent performance across all grinding applications. The triangular shaped ceramic abrasive grain

breaks down in a defined manner and thus continuously produces new sharp cutting edges.

Designed to Endure

The robust construction of Flamethrower Delta™ Grinding Discs guarantees an extended service life, even in the most challenging conditions. Unlike conventional grinding discs, Flamethrower Delta™ features a cooler grinding process and longer life due to an additional grinding layer. This means fewer disc changes, more productivity and less fatigue, saving you both time and cost.

Grinding Discs for Every Application

From automotive repair to industrial fabrication, The Flamethrower Delta™ is the most aggressive stock removal in the ceramic disc line. This product is ideal for tough alloys, stainless steel, aluminum, mild steel and non-ferrous metals. Flamethrower Delta™ is the obvious choice for extreme stock removal, reduced heat and discoloration of workpiece, and the preferred disc for a wide variety of applications.
