Boride AM-K 320 grit bar, AM-K series has a standard size of 152x25x6mm (6”x1”x1/4”). The average grain size in sieving is about 30 microns. The stone of the Coarse category is intended for the final stages of peeling when forming chamfers on a new cutting tool, repairs (removal of notches and chips) and starting grinding operations. Can be used either as an initial stone in the process of grinding previously sharpened and blunted cutting tools, or to remove scratches from coarser stages of roughing, for example, after a 220 grit stone. The recommended grit for the 320 grit step following the Boride AM-K stone is 400 grit (ANSI) Boride AM-K.

The Boride AM-K series is made of aluminum oxide (single crystal white electrocorundum) on a medium hard ceramic bond. AM-K series stones work well with all types of steels and are designed for all stages of peeling, the formation of supplies, repairs of a blade of medium complexity, as well as the initial and main stages of sharpening. The stone is exceptionally good at removing scratches and damage to metal from rough abrasive stones.

A series of grinding stones Boride AM-K is not impregnated, i.e. the inter-abrasive space is not filled with a special composition that prevents the products of processing from getting stuck between the particles of the abrasive (loading). The manufacturer allows working with coarse rough stones (including grit 220 and below) both with lubricating fluids and without the use of any coolant, i.e. dry. The lubricating fluid during operation penetrates into the stone. To improve stock removal performance and comfort, it is recommended to use low density cutting fluid, water, or specialized cutting fluid from Boride Bori-Lube, in this case, as a rule, it is preferable to oil. The leveling of the bar is carried out on glass, on silicon carbide powder. During operation and when cleaning from salting, the use of household detergents is allowed. The Boride AM-K series of whetstones includes a list of whetstones with various abrasive capacities up to 600 grit. The complete set of the AM-K series includes grits: 100, 150, 180, 220, 320, 400, 600 grit in various form factors - 152x25x6mm (6”x1”x1/4”), 152x12x6mm (6”x1/2”x1/ 4”) and 152x25x12mm (6”x1”x1/2”).
