This Two Sides Sharpening Stone is made of extra-hard aluminum oxide, double sided with coarse grit and fine grit.Corundum and white fused alumina.
Orange corundum Whetstone, also known as orange stone, abrasive cutting edges sharp, good finish, high durability.
Hardness similar as corundum ,good toughness, usually better than corundum grinding performance for tool steel, alloy steel, hardened steel molding grinding.
Especially for a variety of cutting tools, measuring tools, instrument parts for finish grinding of workpieces with high requirement.
Gray carbon Whetstone, with high hardness and a certain toughness, hardness second only to boron Whetstone, abrasive sharp, good thermal conductivity.
Using for optical glass, tungsten carbide, titanium, agate, cylinder liner, bearing steel polishing, sharpening high-speed steel cutting tools.
But also for energy originals, ceramics and polishing hard and brittle materials such as boron carbide Whetstone.
It is a high hardness abrasive, grinding capacity, grinding tool for Semis sharpen their own hardness.
Especially wear-resistant, easy out scratches Whetstone, for optical instruments, instrumentation, precision polishing element has a unique role.
