Ann an tagraidhean eile, leithid drileadh bunait, faodar ùird DTH a chleachdadh le pìos singilte ann am meudan tuill suas gu .750 mm (30 ″).Le grunn aonadan ùird CD (drilean cruinneachaidh) tuill drile suas gu 70 ″ no 1778 mm.
Mar riaghailt òrdail, is e an trast-thomhas toll as lugha as urrainn dha òrd DTH drileadh a mheud ainmichte.Bidh òrd 4 òirleach a’ drileadh toll 4 òirleach (102 mm).Is e am bàillidh cuibhreachaidh trast-thomhas a-muigh an ùird, oir, mar a bhios trast-thomhas an tuill a’ lughdachadh, tha sruth-adhair air a chuingealachadh.Is e meud toll as àirde airson drileadh cinneasachaidh meud an ùird ainmichte a bharrachd air 1 òirleach, agus mar sin airson òrd 4 òirleach is e meud an toll as àirde 5 òirleach (127-130 mm).
Tha taghadh an òrd cheart gu ìre mhòr air a dhearbhadh le meud tuill agus seòrsa cruthachadh creige.Gu h-iomchaidh, bu chòir meud an ùird a bhith a rèir meud an tuill a tha a dhìth cho faisg 's as urrainn, a' fàgail dìreach àite gu leòr airson gearraidhean gus an toll fhalmhachadh.
