Klingspor KL 361 JF 3948 Rollo de lija, grano P80, 115 mm x 50 m, óxido de aluminio sobre tejido JF flexible

The Klingspor KL 361 JF 3948 abrasive roll stands out for its highly flexible JF-cloth backing, allowing it to conform to contours and irregular surfaces without cracking or tearing. This 50-metre roll, 115 mm wide, is coated with premium aluminum oxide grain in P80 grit, delivering consistent cutting action and a uniform finish across wood, metal, paint, varnish, and plastics. The resin-over-resin bonding ensures the abrasive remains firmly attached even under heat and pressure, extending the roll's service life in both hand and machine sanding applications.

Highlights

• Flexible JF cotton cloth backing for contour sanding and edge work
• Aluminum oxide abrasive with closed coating for high stock removal and even scratch pattern
• Resin-over-resin bond resists loading and heat, prolonging abrasive life
• 50 m roll length reduces changeover downtime in workshops
• Suitable for wood, metal, painted surfaces, varnish, and plastics

In daily use

Cut to length for hand sanding blocks, or fit to portable belt sanders and orbital sanders for larger surfaces. The P80 grit is ideal for intermediate sanding, removing old finishes, and preparing surfaces for finer grits. The flexible backing prevents edge cracking when sanding profiles, rounded edges, and curved workpieces. The closed coating provides full abrasive coverage, making it efficient on hardwoods and metals while still resisting clogging on softer materials.
