Mounted Point Set
Vitrified Bond, Aluminum Oxide
Hardness grade M
mounted points are made of a
mix of dark red and white aluminum oxide grit in a
vitrified bond.
M is one of the most aggressive abrasive grades.
Ideal for
general use
on steel surfaces, providing
high abrasive and stock removal rates.
Hardness grade O
mounted points consist of pink
aluminum oxide in a vitrified bond. Good edge
holding and long service life characterize hardness
grade O, making it predominant in its field of
application.
Ideally suited for
heavy-duty
edge grinding on
steels. They are noted for their high edge-holding
and dimensional stability, long service life and low
wear.

Resin Bond, Aluminum Oxide
Hardness grade N
mounted points are made
of regular aluminum oxide in a high-quality resin
bond. Tools of hardness grade N are noted for their
elevated hardness and durability.
Hardness grade N tools are perfect for
heavy-duty
edge grinding on stainless steel. These products are
distinguished by their high edgeholding capability,
long service life and low wear.
Grade L
mounted points consist of a mix of white
and dark red aluminum oxide in a high-quality resin
bond.
Hardness grade L
is considered a fairly soft
bond achieving very good removal rates.
ideal for
general use
on stainless steel surfaces.
This hardness grade ensures high abrasive rates and
a high stock removal capability.
