Stone Norton Crystolon Medium 52x52x25mm small

Grinding stone Norton Crystolon 52x52x25mm Medium is an abrasive platform impregnated with a very dense oil with overall dimensions of 52x52x25mm. Norton Crystolon Medium has a good metal removal rate. Appearance of the metal surface of the supply after processing with a Norton Crystolon Medium Fine bar - visually noticeable light scratches. An intermediate stage before finer processing. The grain size is about 80 microns.
Along with one of the most famous stones from the Norton company from the United States of America India Oil Stone - Norton Crystolon is no less popular among fans of sharpening.
Unlike India Oil Stones, Norton Crystolon uses silicon carbide grains, with coarse, medium and fine grains slightly coarser than similar India Oil Stones.
The Norton Crystolon series of stones includes fine (Fine), medium (Medium) and coarse (Coarse) grits.
• The average size of the abrasive grain in the Coarse stone is about 130 microns (P120 according to FEPA classification).
• The average size of the abrasive grain in the Medium stone is about 80 microns (P180 according to FEPA classification).
• The average size of the abrasive grain in the Fine stone is about 45 microns (P320 according to FEPA classification).
The stone comes from the factory impregnated (impregnated) with oil. Norton's 8" Crystolon is made in Mexico. The geometry of the bar from the factory is good, the stone does not require additional alignment, as well as “cheering up” the working surface of the abrasive before the first use. Initially, the stone comes without radial chamfers on the edges (it is recommended to round the edges of the bar before the first use).
The stone bond of Norton Crystolon bar is hard, the stone holds geometry very well, but at the same time has a very high metal removal rate. Works equally well with stainless, high alloy and carbon steels. It is slightly salted, metal shavings and stone working off from its working surface, as a rule, are easily removed with warm water or oil.
Although the stone is oily, it can be used with other coolants that have a lower density than oil to increase the rate of metal removal. For example, when working with water, the metal removal rate increases.
