PCD grinding wheels are a specific kind of
diamond-tipped grinding wheel intended for use with carbide-tipped equipment.
Polycrystalline diamond, or PCD for short, is a type of diamond made by joining
together several smaller diamonds to form a single, bigger diamond. These are
basically used for grinding and polishing hard metals like tool steel and
stainless steel. These wheels are used in a workshop to cut
and grind different types of metal and other workpieces. PCD grinding wheels are
also used to cut and shape complicated workpieces. The diameter of the circle
that goes through the centre of all the studs, wheel bolts, or wheel rim holes
is known as the pitch circle diameter.
