GRINDING
The diamond paper accessory
allows for the Dremel Velocity™ to
be used for grinding away cement,
plaster or thin set. Preparing the surface for tile
replacement is a common application for this
accessory.
The diamond paper needs to be mounted to
the backing pad prior to use.
Select a low to high speed depending on the
material removal rate desired.
The carbide rasp accessory also
allows the Dremel Velocity™ to
grind away cement, thinset mortar,
plaster, and also wood. This accessory is
commonly used to prepare for tile replacement
or rasping wood to smooth a surface or
remove material.

The speed should be set at high speed for
aggressive material removal or at low speed
for a more detailed removal of material.
Do not apply excessive pressure on the tool-let
it do the work.
Corners may be finished using the tip or edge
of the selected accessory, which should
occasionally be rotated during use to distribute
the wear on the accessory and backing pad
surface.
Grind with a continuous motion and light
pressure. DO NOT apply excessive pressure -
let the tool do the work. Excessive pressure
will result in poor handling, vibration, and
premature wear on the diamond paper sheet.
