Boride AM-K 220 grit is one of the roughing stones in the AM-K series that follows the 150 grit stone and serves to remove scratches from the previous stone. The average grain size in the sieving in this bar is about 60 microns. Therefore, this stone is recommended to be used at the end of the roughing stage to complete the initial formation of the knife approach, regrinding, repair (for example, removing notches) and other operations that require the removal of a large amount of metal. The recommended grit for the 220 grit step following the Boride AM-K stone is 320 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”).
