Disco de lixa de velcro PSG Star Flex T29 125-22 grão 40 INOX TLI1252240

Grinding and finishing stainless steel and other metals often means juggling multiple discs and dealing with clogged abrasives. The PSG Star Flex T29 125-22 Grit 40 INOX flap disc solves this by combining aggressive stock removal with a smooth finish in one tool. Its zirconia alumina flaps cut cool and resist loading, especially on INOX, while the conical Type 29 shape lets you work at a comfortable 15–25° angle for fast, controlled grinding.

Who is it for

This flap disc is built for metalworkers, welders, fabricators, and maintenance crews who regularly grind, deburr, or blend stainless steel, mild steel, or non-ferrous metals. It fits any standard 125 mm angle grinder with a 22.23 mm bore and is ideal for shops that need a reliable, all-purpose disc for weld preparation, edge chamfering, and surface conditioning.

Tips

For best results on stainless steel, keep the disc moving and avoid dwelling in one spot to prevent heat discoloration. Use light to moderate pressure and let the abrasive do the work. Always wear appropriate eye and respiratory protection, and check that your grinder's speed does not exceed 12,200 RPM. Store discs flat in a dry place to prevent warping.
