Abrasive manufacturers use a variety of code numbers to identify the abrasive type, grit size, bond structure and treatments of their individual products. It is not practical to identify the various stones and so delapena use a coding system that is common for all stone sizes
Three types of conventional abrasive grit commonly used in honing.
A jagged, splinter like type of free cutting abrasive grit. Used on soft materials such as brass, bronze, aluminium and cast iron, and very hard materials such as carbon, ceramic, and hardened steels.
A regular, chunky shaped grit used for deburring all materials and stock removal in most soft steels up to HRC 50.
A special purified form of aluminium oxide having a cool cutting action. Used on wear resistant materials such as hard chrome and heat-treated steels above HRC 50.
Stones suffixed "s" are sulphur treated. An extreme pressure lubricant that helps to reduce heat, reduces clogging and loading of the stone surface and reduces pick up in softer materials.
A range of polishing stones that will produce a high degree of surface finish on most materials.
A cork stick impregnated with fine abrasive grit used for polishing especially stainless steels.
A cork sticks are predominantly used in plateau honing of cylinder bores.
