Stone used in building the Pyramids of Egypt were smoothed with a naturally "bonded" abrasive--sandstone! Around 2100 B.C. a creative Egyptian engineer mounted a circular wheel on a crude sort of lathe and ground bronze tools and ornaments, launching the art of cylindrical grinding. During the Middle Ages, armor and swords were ground and polished.

Vaccum brazed tools are exceptionaly aggressive as the tight bond allows a very exposed grit. Diamond Grits. FEPA - number indicates the approximate size of the particle in 0.001 mm i.e. D15, D126 etc. The higher the number is, the bigger the grain size is. U.S. Mesh - number indicates the number of holes on a 1"X1" mesh.
GRIT SIZE FOR BONDED ABRASIVES ANSI table1-(8-240 grit) are sized to ANSI B74.12 1976 (R1982) and ANSI table 2 (240-1200 grits) to ANSI B74 . 10-1976 are utilized for sizing for abrasive grains in grinding wheels. This chart is designed to compare millimeters, microns and inches to match them to corresponding ANSI grit sizes.
Applies to products using abrasive grains held in a matrix or bonded to a surface such as coated abrasives, MSL superabrasives, vitrified grinding wheels, dressing sticks, honing stones or grit dressers. Grit sizes are based on ANSI, FEPA, JIS or proprietary grading system standards.

The act of bonding an abrasive grain into a matrix such as glass, resin, rubber or other binder, to create grinding wheels, abrasive stones or sticks that are used to grind, cut, polish, finish or sharpen other objects. Products designed using bonded abrasives are intended to create a specific finish, function at a certain cutting speed, or offer general stock removal to meet a …
The P-version represents the grain size of sand paper and will therefore not be discussed here. FEPA-F is used to determine the grain size of sharpening stones and is therefore relevant. Because many sharpening stones come from Japan, the JIS is still a frequently used way of determining the 'grit' of whetstones.

Please check the application areas, key points of grinding process, and the work conditions of your brushes. 6.Q：Does DAMI use international standard of grit size？ A：DAMI uses the Chinese standard of grit size: chemical composition according to GB/T2480-1996, grit size follows GB/T2481.1-1998.
Factors such as grit shape, bonding material and grit durability can all influence effective fineness. We charted five grit standards using micron grit sizes from 4125μ, down to 0.3μ, and added Shapton stones, ceramic stones, water stones, diamond stones, oil stones and specialized sheet abrasives to create a table of relative fineness.
The grit size indicates the abrasive grade on the abrasive side of the paper. A higher grit number indicates a smaller abrasive grain and a finer abrasive product. A "P" in front of the grit size indicates that the product is graded in accordance with the European FEPA standard ().
