PSG Star Flex STAL T29 125x22mm Disco de lixa de velcro, corindo de zircónio, grão 40, para aço (TLS1252240)

Flap disc with conical T29 shape, 125 mm diameter and 22 mm bore, engineered for aggressive grinding and finishing on steel. Zirconia alumina abrasive on fiberglass backing delivers high stock removal and long life, while the P40 grit handles weld removal, deburring, and edge blending efficiently. Resin-over-resin bonding ensures durability under high-speed angle grinder operation up to 80 m/s (12,200 RPM).

Advantages

Zirconia alumina grain provides a fast, cool cut on steel and stainless steel. The conical T29 profile allows a 15–25° working angle, ideal for heavy material removal and blending on flat surfaces. Fiberglass backing plate adds stability and safety at high RPM. Complies with EN 13743 for abrasive product safety.

Suitable for

• Weld removal and seam blending on steel structures
• Deburring and edge rounding on fabricated parts
• Surface preparation before coating or painting
