KL385 JF Abrasive Cloth 25mm

KL 385 JF abrasives are ideal for sanding by hand on metal and wooden surfaces. A distinct advantage of these abrasives is the ability to fold or cut them to the desired size. This flexibility makes it possible to fit them on an hand block. Remarkably flexible, these abrasive materials are especially ideal for profile sanding on wood, metal, non-ferrous metal surfaces, stainless steel and plastics.

Klingspor has given their KL 385 JF abrasives a cloth backing made of JF cotton. This is characterised by its high flexibility and adaptability. These attributes make this abrasive material ideally suited for work on edges and profiles. Even though furnished with a robust backing, the KL 385 JF abrasive can be torn off by hand easily and cleanly without the help of scissors.

Klingspor uses aluminium oxide as the abrasive grain for KL 385 JF. The stand-out features of this synthetic material are it's block shape and exceptional hardness. Since aluminium oxide is also very temperature resistant, the grain does not suffer from prolonged and intensive grinding. When used for hand sanding, the hard material does not require a high contact pressure to deliver excellent results, allowing for more effortless sanding. The grain is applied to the KL 385 JF with a close coating, resulting in a surface that is covered almost completely. This type of coating is beneficial to work on surfaces made of metal, as it provides for a high stock removal rate while delivering impressive service life at the same time.

The grain applied to the Klingspor abrasive sheets is bonded in place with synthetic resin, which provides for an extra strong hold. The great strength of the bond plays a key role in achieving good work results. The synthetic resin applied as a top size coat over top of the grain provides longevity because it bonds the grain completely to the backing. During sanding, this top size coat wears off from the surfaces of the abrasive grains, allowing them to take full effect.

Abrasive grit is defined by the number of sharp particles per square inch of sandpaper, with smaller grit numbers being coarser and larger grit numbers being finer.
