Faida za bidhaa
Ikilinganishwa na shimo lenye kina kidogo, upoaji wa shimo la kina kirefu na uondoaji wa chakavu cha chuma ni ngumu.Inahitajika kudhibiti uvunjaji wa mabaki ya chuma, lakini pia kudhibiti kiwango cha kuruka na utulivu wa chombo, vinginevyo chombo ni rahisi kuvunja kisu au shimo sio sawa.
Kiini cha kawaida cha kuchimba shimo kirefu: Inafaa kwa usindikaji wa shimo la kina la chuma, chuma cha kutupwa na vifaa vingine
