Black Piranha is formulated inhouse and manufactured by Hardrock uk standards.

Black Piranha Granite blades are a Premium diamond bond alloy hot pressed segmented diamond blade. with 40/45 diamonds grit, then cold gas dipped. This hardens the alloy but is left soft in the centre to allow for exposing diamond. The vast forced cold shrinks micro gas pockets in the metal. There is a huge 10mm heigh segment for extra ware they last a long time. Diamond content is around 30% and cut grate says many customers’ members.

Specialist ultimate diamond quality and selected hot pure metal formulas. We sell cheaper blades but there not as good as this one’s. I would use it on most materials that are hard. 
Can be used Wet or Dry.
