Poliflex® Tools
General Information
Safety recommendations
For safety reasons, it is imperative to remain
within the stated RPM limit at all times.
= Wear eye protection!
= Read the instructions!
Poliflex® fine-grinding tools are designed for
the following maximum peripheral speeds:
PUR
= 15 m/s
PUR-STRUC = 15 m/s
