Flap disc - zirconium grain
HERMAN LR-42 Area
For stainless steel

Recommended angle during machining 15˚ - 25˚:
the conical shape of the T29 disc pad in combination with radially arranged lamellae of two different sizes significantly increases the contact area

Primary raw material - high-quality sanding belts with an applied layer of zirconium corundum abrasive grains (50% zirconium):
long service life and very good material removal when machining stainless steel and higher strength steels

Abrasive backing type:
Poly-cotton

Lamellae of the same shape, but in two different sizes and grain sizes, arranged in such a way that the narrower upper lamella with a larger grain size only partially overlaps the wider lower lamella with a smaller grain size:
the disc has two layers of lamellas at the most stressed places (around the perimeter), thus achieving a longer service life and after the wear of the upper lamellas with aggressive removal, the lower lamellas are still available for finer finalization of the surface of the processed material

Lamellas machine-cut from sanding belts and laid radially around the perimeter with an accuracy of 0.5mm:
precise final product for efficient work

Plate mat made of 7-layer fiberglass:
high structural safety and destruction resistance

Special glue based on epoxy resin:
for a secure connection of the slats to the base plate

Optimal number of lamellae for efficient machining:
chosen depending on the diameter and grain size of the tool

The grain size is standard in the range of P40 to 120 according to FEPA (100 to 500 µm):
enables the selection of a suitable tool from rough grinding to fine finishing work
