FEIN 63717301010 Fiber Sanding Disc 125 mm Grit P36 Zirconia Alumina 25-Pack

Fiber sanding discs with aggressive zirconia alumina abrasive for high stock removal on steel and stainless steel. The 125 mm diameter and P36 grit make these discs ideal for rapid grinding, deburring, and weld seam processing. The vulcanized fiber backing provides durability and flexibility, while the resin-over-resin bonding ensures long life under high pressure. Each pack contains 25 discs with a 22.23 mm bore for standard angle grinders. Maximum operating speed 80 m/s (12,200 RPM).

Advantages

Zirconia alumina abrasive delivers exceptional cutting performance and extended service life. Closed coat construction provides full surface coverage for consistent finish. Vulcanized fiber backing resists tearing and withstands high mechanical loads. Resin-over-resin bonding enhances heat resistance and disc stability. Suitable for demanding applications such as weld removal, edge chamfering, and surface preparation.

Suitable for

• Aggressive grinding of steel and stainless steel
• Deburring and edge breaking
