Koch grinding paste Green

Koch grinding paste, for fine grinding of chisels and knives. The grit is 2500. In combination with the felt discs, it works great! Fast, amazing results. This grinding paste has good cooling properties that also allow tools made of tool steel to be sharpened quickly without overheating them.

The burr that develops when grinding is removed with this paste, which is used on the felt wheels of Koch grinding machines, among others. With 1 kilo of paste, you can grind about 3000 times.

There is also a grinding paste grain 3500 (blue).

In use

The grinding paste is used in combination with felt discs mounted on a motor. As with the Koch grinder. It goes super fast and the result is amazing. I wouldn’t believe that you can “polish away” grit 80 marks with polishing paste 2500. But it does, and it happens with unprecedented speed and ease! The felt wheels are made of special felt, varying in hardness and enriched with aluminium oxide. Soft felt discs for quick material removal and hard felt discs for even polishing. (The yellow disc is for round profiles and the green one for straight ones, e.g. chisels).
