ʻO DIN338 HSS pahu pahu pahu pololeis he mea hana maʻalahi a koʻikoʻi no ka ʻeli ʻana i nā ʻano mea like ʻole, me ka alumini. Hoʻolālā ʻia kēia mau drill bits e hoʻokō i nā koi koʻikoʻi o ka German Institute for Standardization (DIN) a ua ʻike ʻia no kā lākou hana kiʻekiʻe a me ka hana pololei. Ma kēia ʻatikala, e ʻimi mākou i nā hiʻohiʻona, nā noi, a me nā pōmaikaʻi o DIN338 HSS straight shank drill bits, me ka nānā pono ʻana i ko lākou kūpono no ka wili alumini.
ʻO DIN338 HSS pahu pahu pahu pololeis ua hana ʻia mai ke kila kiʻekiʻe (HSS), he ʻano kila mea hana i ʻike ʻia no kona ʻano paʻakikī, ʻaʻahu kūpaʻa, a hiki ke kū i nā wela kiʻekiʻe. ʻO ka hoʻolālā shank pololei o kēia mau drill bits e hiki ai ke hoʻopaʻa paʻa a paʻa i loko o nā ʻano hana drill rigs, e kūpono iā lākou no nā noi wili paʻa lima a paʻa. Hōʻike ia i kahi hoʻolālā shank pololei i kūpono i nā hana uila lima lima a i ʻole ka hana lima. ʻO ka ʻoki ʻoki o kēia drill bit ua wili ʻia, hiki ke ʻoki koke i nā mea hana a wehe i nā ʻāpana, e hoʻomaikaʻi ana i ka pono wili.
ʻO kekahi o nā hiʻohiʻona nui o kaʻO DIN338 HSS pahu pahu pahu pololei ʻo ia kona mau ʻūhā ʻāina pololei, i hoʻolālā ʻia e hoʻoneʻe pono i nā ʻāpana a me nā ʻōpala mai ka wahi wili ʻana, e loaʻa ai kahi puka maʻemaʻe a pololei. Kōkua pū nā ʻāwīwī i ka hoʻohaʻahaʻa ʻana i ka friction a me ka hoʻoulu ʻana i ka wela i ka wā o ke kaʻina hana wili, ʻo ia ka mea nui loa i ka hana ʻana me nā mea i maʻa a paʻa, e like me ke alumini.
Hāʻawi ka DIN338 HSS i nā pono he nui i ka wā e wili ai i ka alumini. ʻO ka alumini he metala palupalu a māmā e koi ana i kahi ala wili kūikawā e loaʻa ai nā hopena maʻemaʻe a pololei. ʻO ke kūkulu kila kiʻekiʻe o kēia mau drill i hui pū ʻia me ko lākou mau ʻoki ʻoki ʻoi e hiki ai iā lākou ke komo pono i ka alumini me ka hoʻoikaika liʻiliʻi, e hōʻemi ana i ka hopena o ka deformation a i ʻole ka pōʻino o ka mea hana.
Eia kekahi, ʻo ka geometry groove o DIN338 HSS straight shank drills i hoʻopaʻa ʻia no ka hoʻokuʻu ʻana i ka chip, e pale ana i ka hoʻopaʻa ʻana a me ka hōʻoia i ka hoʻomau ʻana a me ka hoʻoneʻe ʻana i nā mea i ka wā o ke kaʻina hana. He mea kōkua nui kēia i ka hana ʻana me ka aluminika, no ka mea, kōkua ia i ka mālama pono ʻana i ka pono o ka mea a pale i nā burrs a i ʻole nā ʻaoʻao ʻāʻī mai ka hana ʻana a puni ka lua i wili ʻia.
Ma waho aʻe o ko lākou kūpono no ka hoʻohana ʻana me ka alumini,ʻO DIN338 HSS nā hoʻoheheʻe maʻamau pololei hiki ke hoʻohana ʻia e wili i nā ʻano mea ʻē aʻe, e like me ke kila, ke kila kila, ke keleawe, a me nā plastics. Hoʻolilo kēia iā lākou i mea waiwai nui a maikaʻi hoʻi i nā hale hana, nā hale hana, a me nā kahua kūkulu, kahi e loaʻa ai nā koi wili like ʻole.
Ke wili ʻana i ka alumini me kahi drill shank pololei DIN338 HSS, he mea nui e noʻonoʻo i ka wikiwiki a me ka helu hānai e hoʻomaikaʻi i ke kaʻina hana wili. Hiki ke hoʻopili maʻalahi ka alumini i ka ʻoki ʻoki o ka drill, no laila me ka hoʻohana ʻana i nā wikiwiki kiʻekiʻe a me nā helu hānai haʻahaʻa hiki ke kōkua i ka pale ʻana i kēia a hana i kahi lua maʻemaʻe. Eia kekahi, ʻo ka hoʻohana ʻana i ka lubricant a i ʻole ka ʻoki ʻana i ka wai i hoʻolālā ʻia no ka alumini hiki ke hoʻomaikaʻi hou i ka hana a me ke ola o ka drill.
