The Starcke cloth material 542JFF and 531JFF used for the round bulb sanders, is slightly thinner than the VSM KK711E material used in our cylindrical sleeves but has the same properties, making it ideal for the round sander. The main material we use on the round and drum sleeves is a cloth backing which is extra sturdy but at the same time extremely flexible. Gluing of the aluminum oxide grain is done in several layers for optimum bonding of the grain to the cloth backing. The overlapping design of each sleeve for the round and small round sander is hand made, not machine made. It’s the only way we can make them and results in a high-quality product where the grain doesn´t come off, even when doing real tough sanding jobs, including steel sanding. One small test that shows the quality of abrasives is to fold and squeeze the abrasive between your fingers and role the abrasive back and forth. With inferior quality abrasives, you will see how the grains delaminate from the backing material. This is not the case with sanding sleeves. The sharpness of the abrasive lasts a long time, however, we highly recommend using a cleaning stick to considerably extend the working life of each sleeve.

The cloth backed sanding sleeves are highly flexible and made of the very best quality, sanding not only wood but also metals, plastic, bone and horn. To ensure maximum performance, it is therefore essential that only original long-life sanding sleeves be used. On the round sander, the improved and original overlapping design of the sanding sleeves is to ensure longevity and optimum effectiveness in awkward places. As the sanders are both round and soft the tendency for them to be clogged by dust and resin is very small compared, for example, with rotating paper discs. The sharpness of the abrasive lasts a long time, however, we highly recommend using a cleaning stick to considerably extend the working life of each sleeve. Cleaning sticks are included in each sanding set and are also available separately.

• Particularly well suited for round, curved, bulging or cup-formed shapes
• Excellent for sanding concave surfaces like the inside and bottom of carved or turned bowls and perfect for sanding cups and spoons
• Reaches hard to reach contoured areas, which before could only be done by hand sanding
• Sands wood, metals, plastic, bone and horn
• The sanders actually become flat when pressed against a flat surface and contour or round when pressed against a round surface i.e. the sanders conform to the underlying surface. Consequently, the sanders should be filled with very little air
