Semi-open coating for flawless results
The semi-open coating ensures that the swarf is cleanly removed from the surface. It also delivers exceptional grinding performance at only moderate stock removal. This technology is a particularly good choice for all applications on hard wood, varnish, paint and fillers. The abrasive roll PL 31 B can produce coarser or exceptionally smooth surfaces depending on the selected grit. While a coarse grit is primarily recommended for smoothing out surfaces or chamfering edges, a fine grit – 220 or higher – is the grit of choice for surface finishing. It is advisable to break up the grinding process into multiple steps to ensure optimum efficiency and perfect results. You start off by working with a coarse grit first. You then proceed with a succession of finer grit sizes until you produce the desired result.
Hard, tough and effective – that is aluminium oxide in a nutshell
Aluminium oxide is a widely used abrasive, also used by Klingspor for the abrasive roll PL 31 B. Its tremendous hardness makes this mineral the preferred choice for many products, e.g. abrasive paper and cutting-off wheels. Glue is used to bond the material to the B-paper of the abrasive roll PL 31 B.
