Bi-Metal Hole Saw Drill Bit HSS Hole Cutter no ka Laau a me ke Metala
Hōʻike Huahana
Hoʻolālā ʻia me nā ʻāpana oval elongated, ua hoʻolālā ʻia kēia bit e wehe maʻalahi i nā kohu lāʻau mai nā papahana hana lāʻau a laila hoʻomaha maikaʻi iā lākou.Hiki ke hoʻohana ʻia kahi mea hoʻoluʻu e like me ka wai e pale ai i ka wela i ka wā o ka hana ʻana.
Ke hoʻohana nei i nā mea bimetallic kiʻekiʻe, ʻo kēia huahana he rust-proof, 2mm mānoanoa, ʻoi aku ka lōʻihi, a he 50% ka lōʻihi o ke ola lawelawe;hōʻike ia i ke kūpaʻa corrosion maikaʻi a me ka pale wela pū kekahi.Hāʻawi ka hana bi-metal i ka ʻoi aku o ka ʻoʻoleʻa, kūpono ia no nā mea hoʻohana e ʻimi nei i kahi ala wikiwiki a maʻemaʻe e ʻoki ai i ka metala.Paʻa loa nā ʻāpana Zinc, kūpaʻa i ka corrosion, a paʻakikī loa e ʻoki.
Me ka maka niho, ʻoi aku ka wikiwiki a me ka maʻalahi o ka ʻoki ʻana.He mau niho ʻoi kona e hāʻawi ana i nā ʻoki maʻemaʻe a maʻemaʻe.He pololei loa ia, a ʻokoʻa ma waena o 43mm a 50mm ma muli o ka nui o ka lua i ʻoki ʻia.
Aia ka ʻōlelo aʻo ʻaʻole ʻōlelo ʻia kēia ʻike lua no ka hoʻohana ʻana i ke kaʻa, ke kīleʻa seramika, a me ka metala mānoanoa.ʻAʻole i hoʻolako ʻia me ka mandrel a me ka drill pilot.
