How 3M Precision-Shaped Grain works:

3M precision-shaped grain
is designed to continuously
fracture to form sharp points
and edges that easily “slice”
through metal. It cuts faster,
lasts longer and stays cooler.

Conventional ceramic abrasive
grain tends to “plow” through
the metal, causing heat to
build up in the workpiece and
the abrasive – resulting in a
slower cut, shorter belt life
and undesirable effects,
such as burnishing.
