I-Bi-Metal Hole Saw Drill Bit HSS Hole Cutter Yokhuni Nensimbi
Umbukiso Womkhiqizo
Idizayinelwe ngama-oval grooves amade, le bit yakhelwe ukususa ukushefa kwezinkuni kumaphrojekthi wokwenza izinkuni kalula bese ipholisa phansi ngempumelelo. Isipholile esinjengamanzi singasetshenziswa ukuvimbela ukushisa ngokweqile ngesikhathi sokumba.
Usebenzisa ikhwalithi ephezulu yezinto ze-bimetallic, lo mkhiqizo awufaki ukugqwala, ugqinsi ongu-2mm, uhlala isikhathi eside, futhi unokuphila kwesevisi okude okungu-50%; ikhombisa ukumelana nokugqwala okuhle nokumelana nokushisa. Ukwakhiwa kwe-bi-metal kunikeza ukuqina okukhulayo, okwenza kube kuhle kubasebenzisi abafuna indlela esheshayo, ehlanzekile yokusika insimbi. Ama-alloys e-Zinc ahlala isikhathi eside ngendlela emangalisayo, awakwazi ukugqwala, futhi kunzima kakhulu ukuwasika.
Ngensingo enamazinyo, ukusika kuyashesha futhi kubushelelezi. Inesethi yamazinyo abukhali anika amanxeba ahlanzekile, abushelelezi. Iphinde inembe kakhulu, futhi iyahlukahluka phakathi kuka-43mm kuya ku-50mm kuye ngosayizi wembobo esikwayo.
Kunesexwayiso sokuthi le saha yembobo ayinconywa ukuthi isetshenziswe kukhonkolo, ithayela le-ceramic, noma insimbi ewugqinsi. Ayifakelwe i-mandrel kanye ne-pilot drill.
