Solid Hard Metal Bits

• Diameters from 5 mm.

• Regrindable.

• Very fragile in the presence of vibrations.

• High drilling precision.

Bits with Inserts

• Diameters from 13 mm.

• High productivity.

• Longer duration than solid bits.

• Less precise drilling compared to solid bits.

Drilling FGNM steel profiles is not particularly difficult but it is important to use tools that are suitable for drilling extremely hard steels.
