Rubi Diamond Manual Polishing Pad - Grit #400

The RUBI diamond rubber studs are semi-flexible and their EVA rubber body allows an excellent adaptation to the user's hand. The grip area has a lateral groove that increases the ergonomics of the block and reduces fatigue of the hand during use. The diamond rubber studs are designed to work manually on areas where access with power tools is very complicated, such as interior angles, hollow areas or corners and for roughing and smoothing chipped or sharp edges. In order to achieve a good result, both the type of material and the state in which it is found must be taken into account. RUBI diamond rubber studs can be used dry but wet use is recommended, either by moistening the plug or providing a source of continuous cooling. The range of RUBI diamond rubber blocks comes in different granulometries to perform different polishing and finishing tasks. It is very important that in the polishing work a stepwise degradation is carried out using the different grains successively, starting with the largest grain to the smallest. In the works of roughing and / or smoothing of edges, the movement of the block must go, always, from the top (most visible) to the bottom. This reduces the risk of chipping or material damage.
