Klingspor KL 361 JF 3913 hiomanauharulla P40 100 mm x 50 m

For coarse sanding and rapid stock removal on metal, wood, plastics, paint, varnish, and filler, the Klingspor KL 361 JF 3913 abrasive roll stands apart through its very flexible JF cotton backing and high-performance aluminium oxide grain. Unlike stiffer abrasives that crack or tear on contoured surfaces, this roll conforms cleanly to edges and profiles, making it a reliable choice for hand sanding, orbital sanders, and belt sanders cut to size.

Highlights

• P40 grit aluminium oxide with a closed coating for aggressive material removal and a consistent scratch pattern.
• Very flexible JF cotton backing resists creasing and adapts to irregular shapes without sacrificing durability.
• Synthetic resin bonding keeps the abrasive firmly attached even under high heat and pressure.
• 50 m roll length and 100 mm width allow economical cutting to custom lengths for any sanding tool.
• 76 mm core diameter fits standard roll dispensers and workshop holders.

In daily use

This roll is built for coarse preparation work: stripping old finishes, deburring metal edges, levelling filler, or shaping wood before finer grits. The closed coating delivers a uniform finish with fewer stray scratches, while the flexible backing lets you wrap the abrasive around pipes, profiles, and corners without cracking. Because it is supplied on a roll, you can cut exactly the length needed for a hand block, orbital sander, or belt sander, reducing waste and keeping your sanding station organised.
