Brass dowel pins are - despite the chamfer on the edge - only partially resistant to shear forces. Wherever the pin be driven with snow plows, forklifts or similar vehicles, we recommend the flush installation with the help of our special-step drill.
Drilling and sinks in a single operation; especially for all pins of the 11H-series constructed.
Tool fixture: SDS-plus.

    Longer service life by three carbide cutting
    optimal cutting geometry is particularly
    quiet operation when lowering

Through this cutting arrangement allows reductions in uneven or sloping floors bring variable depth reduction.
