The ultimate solution for workpieces with slight contours

The best choice for sanding workpieces that possess slight contours. Exceptionally flexible and tear-resistant, this premium abrasive belt proves to be ideal for processing

  • wood
  • wood-based material
  • non-ferrous metal
  • plastic

Effective and elastic - the flexible cotton backing with closely coated aluminium oxide

Its flexible cotton backing allows it to contour snugly to the workpiece at hand. These properties allow every skilled craftsman to achieve sanding results of flawless quality with this belt. The J-weight cotton for the backing of this product is flexible, yet exceedingly stable and tear-resistant at the same time. The aluminium oxide grain is applied to this backing with a close coating. This ensures that the backing is almost entirely covered by abrasive grain. Aluminium oxide is distinguished by its combination of ruggedness and toughness. What is more, the close coating of the abrasive grain ensures a uniform scratch pattern as it spreads the applied force across a large number of grain points. This coating is responsible for the uniform and finely structured surface the product leaves behind on wood and wood-based material.

    These have been the best belts we've found for our needs. We are milling aluminum and use them on our belt sander to clean edges. They last much longer than other options we've tried prior! Fast shipment and great pricing. ..

    I have been buying bandsaw blades at Skookum for sometime. Always happy with the product. I ordered 4 special order in 2022 but didn't use them until 2024. They were the wrong length.

    The blade fits my experienced B/D hobby saw. It cuts well and I'm able to run the saw as it was intended with both tyres installed. I would like to note that both Ryan and Rob exceeded expectations in their service with me. My compliments to both. All on line vendors should take lessons. Thanks..
