The drilling of a pipe through PE outlet saddles can be made with a Classic drilling device for the 4 existing dimensions: PE32, 50, 90 and 110; and with the HDT drilling device for PE32 and PE50 outlets.
Both the Classic and the HDT drilling device are compatible with the OPTIMQ PE/PVC hole cutters.
To drill cast iron pipes the HDT drilling device works with Starrett or similar hole cutters and the Classic drilling device with the OPTIMQ DI hole cutters.
