

RECOMMENDEDTOOLS

QuickChange System and Tooling feature extremely fast and convenient tool changes, and a

long tool

life, providing for great long‐term 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.



V‐HARR® Premium Polishing Pads are designed for mechanically polishing and restoring concrete; also ideal for

terrazzo and

hard stone floors. V‐HARR® 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 diamond‐impregnated pads for floor maintenance. Available in a variety of sizes, and are

great for

daily use. When used wet, they require only water (no wax or chemicals needed) and are a very environmentally

friendly solution

for maintaining floors.
