Bar BORIDE CS-HD 1000grit 150x25x6mm

CS-HD series Boride stone in 1000 grit, standard size - 152x12x6mm (6”x1/2”x1/4”). The average grain size in sieving is about 4 µm. The stone is intended for the stages of proof. Used to remove scratches from preliminary sharpening steps, such as after a Boride CS-HD 800 grit bar. The recommended grit for the 1000 grit step following the Boride CS-HD stone is 1200 grit (ANSI) Boride CS-HD.
The Boride CS-HD series is one of the few whetstone series produced by Boride that is based on silicon carbide grit. The Boride CS-HD series has medium-hard bonds and, thanks to the silicon carbide abrasive grain, works equally well with both carbon and chromium, high alloy and powder steels. The Boride CS-HD series has extended hardness recommendations for machined steels from hard knife steels to fairly soft stainless materials.
The Boride CS-HD series works with both oil and water coolants, however, since the Boride CS-HD series of whetstones is not impregnated, i.e. the inter-abrasive space is not filled with a special composition that prevents the processing products from getting stuck between the particles of the abrasive (salting). 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 Boride Bori-Lube specialty cutting fluid in this case, as a rule, it is better than oil. The leveling of the bar is carried out on glass, on silicon carbide powder. During operation and cleaning from salting, the use of household detergents is allowed. The Boride CS-HD series works equally well on both hard tool and carbon steels and soft chromium steels. The Boride CS-HD range of whetstones includes whetstones with abrasive capacity only in the roughing range of 120, 150, 220, 320, 400, 600, 800, 1000, 1200 grit in various form factors - 152x1”x1/4” and 152x25x12mm ( 6”x1”x1/2”).
