RECOMMENDEDTOOLS
QuickChange System and Tooling feature extremely fast and convenient tool changes, and
a long tool
life, providing for great longterm cost savings. The QuickChange pads are
produced in four different
bonds for super hard, hard, medium and soft concrete, in a variety of
grit sizes. They are offered with
1 or 2 buttons or rectangular segments, which allows you to customize the aggressiveness of the
cut.
Calibra grinding discs: our popular ceramic bond discs are designed for the removal of difficult
scratches
and they save you valuable time by eliminating the need for multiple passes with metal
tools. They can be
used wet or dry, and are best for hard concrete applications.
They are 3-inch, with included Velcro back attachment.
NATO® polishing discs feature a special resin formula designed for both wet and dry applications and a unique
design with
wide channels allowing for work on a cleaner surface and ensuring a quality polish. Available in 3 and 4
in sizes. They are with
included Velcro attachment.
VHARR® Premium Polishing Pads are designed for mechanically polishing and restoring concrete; also ideal for
terrazzo and
hard stone floors. VHARR® pads are offered in a wide variety of diameters and grit sizes to
accommodate many applications.
Dry use is strongly recommended.
Shine Pro® are high quality diamondimpregnated pads for floor maintenance. Available in a variety of sizes, and are
