Abrasive non-woven roll KLINGSPOR NRO400 115 mm grit 400 length 10 m

KLINGSPOR NRO400 abrasive non-woven roll, 115 mm wide and 10 m long, is designed for fine surface finishing tasks on metal, wood and painted substrates. The open-structured nylon non-woven material carries fine abrasive grains (grade 400) that provide a consistent, smooth finish without creating deep scratches. The flexible roll conforms to contours, edges and profiles, allowing controlled blending, light deburring and satin finishing across flat and shaped surfaces.

Advantages

The non-woven structure ensures even material removal and a uniform surface appearance while preventing aggressive cutting typical of conventional abrasives. Its flexibility allows access to curved and irregular shapes, and the fine grit produces minimal sanding marks suitable for pre-paint preparation and final finishing. The roll format provides continuous length for custom cutting to required widths or shapes, reducing waste and enabling efficient workflow.

Suitable for

• Feathering and blending paint edges on automotive and industrial panels
• Light deburring and surface blending on metal parts
• Satin finishing and smoothing of wood surfaces before final coating
• Cleaning and fine sanding of painted and varnished surfaces
• Profile and edge work on contoured components

Key specifications

• Material: open-structured nylon non-woven with abrasive grains
• Grit: 400 (fine)
• Width: 115 mm
• Length: 10 m (continuous roll)
• Finish result: fine, scratch-free satin surface
• Compatible tools: hand sanding, sanding blocks and light rotary tools

How to use

Cut the roll to the desired length and, if necessary, to the required width for the application. Use by hand or mount on a suitable sanding block; apply light, even pressure and move the abrasive along the workpiece following the grain or contour. For metal surfaces, begin with a test area to confirm the finish and adjust pressure or motion as needed. Replace the section when abrasive efficiency decreases or when clogging occurs.

Usage recommendations

For best results on painted surfaces, keep movements consistent and finish with light passes to avoid visible transitions. When working on metals, use clean, dry conditions and consider a finishing product or protective coating after sanding to prevent oxidation. Store the roll in a dry, dust-free environment to maintain abrasive performance.
