目前(qian)潛孔鉆(zhan)頭大都采用球(qiu)(qiu)型(xing)鑿(zao)巖合(he)金齒頭部和花鍵形尾柄(bing)。鉆(zhan)頭合(he)金可根據形狀分為半(ban)球(qiu)(qiu)齒、錐形齒、拋物(wu)線齒等(deng)多種(zhong)類型(xing)。半(ban)球(qiu)(qiu)齒承載能力強,耐磨(mo)(mo)性好,適合(he)鉆(zhan)鑿(zao)堅硬、中(zhong)硬及磨(mo)(mo)蝕性巖石
潛孔鉆(zhan)頭(tou)型號:qk880-6j-oh、qk880-6jg-oh、qk980-6j-oh、qk1090-6j-oq、qk13105-8jgb-oq、qk13114-4j-oq、qk13113-4j-oq、qk13114-8jg-oh、qk13115-8jg-oh、qk18165-8jg-oh、qk24175-6j-og等潛孔鉆(zhan)頭(tou)釬(han)頭(tou)直徑:65~130mm。
