Diamond Sharpening stone Poltava Expert Pro 550 grit

Detailed information

Product detailed description

EXPERT PRO - polymer (metal-resin) bonded stones with diamond powder. This range is ideal for finishing sharpening and gives a perfectly shiny cutting edge due to the softness of the bond, can also be used for full cycle sharpening (depending on the hardness of the steel). Works well in combination with PREMIUM BRONZE ranges. Produced from 60 GRIT to 15000 GRIT

Diamonds offer excellent performance when sharpening knives from any steel. The stone consists of a 3 mm thick diamond plate mounted on a high-quality aluminum blank. A diamond bearing plate contains evenly distributed diamond grains. The production of bonded diamonds is more complex than the production of coated diamonds. Bonded diamonds provide better feedback and give the grindstone a much longer life.

 

Stone properties:

  • grain size (40/28 µm) 550 grit
  • dimensions of the grinding part: 150(L) x 25(W) x 3(H) mm
  • dimensions with blank: 160(L) x 25(W) x 7(H) mm
  • thickness of the diamond layer: 3 mm
  • diamond powder concentration: 100%
  • Expert Pro Diamant are ideal for sharpening knives made of any steel or for final grinding, polishing

 

Advantages of sharpening knives with Expert Pro Diamond stones:

  • Comfort when working — the stone is hard enough, but comfortable to work with. It is often compared to Japanese water stones, but diamond is much more durable than them.
  • Undemanding — stones do not require additional care, which cannot be said about natural and synthetic stones for sharpening knives. These stones do not require the application of cutting fluids (coolants).
  • Versatility - different grains of stones but of the same size allows you to change the stones depending on the processing phase without changing the sharpening angle of the knife
  • High performance diamond for sharpening knives — an excellent result is achieved thanks to the concentration of 100% diamond grain

 

How to use:

  • it is possible to grind dry with stones, but for grain sizes smaller than 50/40, we recommend using soapy foam or baby oil johnson baby
  • we recommend micellar water for cleaning stones
  • bars are restored in the process of salting with pumice, abrasive tools, silicon carbide powder on a flat surface

 These stones are suitable for TsProf, Hapstone, Kazak.

The history of the enterprise dates back to 1966 when it was established as “Poltava Plant of Synthetic Diamonds and Diamond Tools” following the country’s directive to develop and master the technology of diamond synthesis and diamond tool production.

In 1966, diamond powder was synthesized for the first time at the plant. Within a short period, the plant became the largest producer of grinding and micro-powders of synthetic diamonds in the USSR.

Today, PJSC “Poltava Diamond Tools” is a modern enterprise specializing in the production of a wide range of diamond and CBN tools for the manufacturing and sharpening of tools made of hard alloys and high-speed steels; grinding and polishing of parts made of hard alloys, heat-resistant, alloyed, and stainless steels, glass, ceramics, silicon, refractory materials, precious stones, and other materials; cutting of products made of hard alloy, glass, marble, granite, quartz, ceramics, and construction materials; drilling of glass and highly reinforced concrete, and more.
