Sleeves and Caps

Our sanding sleeves are largely provided by Lukas, a German manufacturer with a very broad program in the field of sanding and grinding.

Sanding sleeves and speeds

We roughly distinguish sanding sleeves into two forms. We know the conical sanding sleeve and the cylindrical sanding sleeve. The sleeves are attached to a straight grinder or pencil grinder via a holder. Depending on the diameter of the sanding sleeve and the hardness of the mandrel you determine the speed. The smaller the sanding sleeve, the higher the speed can be. A sleeve of 10x20mm, for example, requires 57,000 rpm. A large diameter of 75 mm you can use a maximum speed of 6,500.
Further, a soft abrasive sleeve holder requires significantly fewer revolutions than a hard holder.

Sanding sleeves and holders

A hard holder is most commonly used. The soft holder is used when contours need to be followed. Of course we are happy to give you advice.

Sanding sleeves and CubitronII

A separate quality of abrasive sleeves is the CubitronII quality from 3M. On the initiative of Metaaltechniek, 3M has developed this product in their product range. The sanding sleeves in this quality are enthusiastically received by the user. The Cubitron™ II mineral provides a very high cutting power, is more aggressive and faster and causes less heat formation. In addition, you are assured of a uniform finish and Cubitron II abrasive minerals have an extremely long service life. This is because the minerals have a pointed shape and are oriented vertically toward the workpiece to penetrate deep into the metal. The minerals wear off evenly and retain their triangular shape. This ensures limited heat generation and a cost-effective tool life.
