What is the difference between T27 and T29 flap discs?
T27 (flat) is ideal for grinding flat surfaces and finishing large areas. T29 (angled) works best for welds, edges, and curves. Choose T29 for heavy metal removal and weld grinding, and T27 for woodworking or paint prep.
What’s the difference between a Strip Disc and a Flap Disc?
Strip Discs remove paint, rust, and adhesives without harming the base material. Flap Discs handle grinding and finishing. For best results, use Strip first to clean the surface, then Flap to smooth and prepare for finishing.
What materials can these discs be used on?
Made with premium zirconia abrasive, these discs work great on steel, stainless steel, aluminum, wood, and plastics. They are especially effective for metal surface prep and weld grinding.
