Step drag bit yaiku bor sing biasane dirancang kanggo digunakake ing formasi alus kayata wedhi, lempung, utawa sawetara watu alus.Nanging, ora bakal bisa digunakake kanthi apik ing kerikil kasar utawa formasi watu atos.Panggunaan kalebu sumur banyu pengeboran, pertambangan, panas bumi.lingkungan lan pengeboran eksplorasi.Yen bisa, padha kudu digunakake kanggo pengeboran bolongan pilot amarga padha gawé cuttings sing paling gampang kanggo log.
3 wings step drag bits minangka salah sawijining konstruksi baja campuran baja kanthi tip nglereni karbida tungsten lan sisih ngukur kanggo njamin umur sing luwih dawa.Wis 3 wings lan 3 bolongan flushing.Dibandhingake karo 4 wings, 3 wings langkah seret bit cenderung kanggo pengeboran luwih cepet lan agresif, dene, sing luwih cendhek tahan lan kurang awet.3 wings langkah gaya seret bit bakal gawé cuttings luwih gedhe saka gaya chevron bit seret.Kacepetan tabel rotary bit seret langkah kudu antarane 60 lan 80 rpm kanthi bobot entheng (WOB).
3 wings step drag bit minangka alat sing ekonomis nalika ngebur formasi geologi sing luwih alus lan jero sing luwih cethek, utamane dirancang kanggo formasi tomedium alus, kayata Clay, Loam, Silt, Lemah paling alus nganti medium sing nduweni kelembapan, lan liya-liyane. dianjurake kanggo pengeboran ing Pertambangan, Eksplorasi, Lingkungan, sumur banyu, Geo Exchange, lsp.
