ʻO ka HSS twist Drill Bit me ka oxide ʻeleʻele Finish
Nā hiʻohiʻona
1.High Speed Steel (HSS) hana
2. Hoʻolālā Tapered:
3.The black oxide ma luna o ka lapaʻau
4. Ua hoʻolālāʻia kēia mau mea hoʻoheheʻe e like me nāʻano hana wili, e hāʻawi ana i ka maʻalahi o ka hoʻohana a me ka versatility no nā hoʻonohonoho mīkini likeʻole.
ʻO ka holoʻokoʻa, hāʻawi ka ʻāpana HSS twist drill bit me ka hoʻopau ʻeleʻele ʻeleʻele i ka lōʻihi, ka pololei, ka pale ʻana i ka corrosion, a me ka versatility, e lilo ia i mea waiwai no nā ʻano pono wili.

1.Heat resistance: Hiki i nā mea kila kiʻekiʻe ke kū i nā mahana kiʻekiʻe i hanaʻia i ka wā e wili ai, e ho'ēmi ana i ka hopena o ka wela a me ka mālamaʻana i ka pono o kaʻokiʻana.
2.Precision Drilling: ʻO ka hoʻolālā tapered e hiki ai ke hoʻonohonoho maikaʻi a me ka pololei, i mea kūpono no ka hanaʻana i nā puka kiko'ī i nā mea likeʻole.
3. ʻO ka spiral flute design e hoʻoikaika i ka hoʻokuʻu ʻana i nā puʻupuʻu maikaʻi, e hōʻemi ana i ka pilikia o ka clogging a me ka hoʻomaikaʻi ʻana i ka hana wili.
4. ʻO ka tapered HSS twist drill bit me ka ʻeleʻele oxide coating e kūpono no ka wili ʻana i nā ʻano mea like ʻole me ka metala, ka lāʻau, ka plastic a me nā composites, e hāʻawi ana i ka versatility i nā noi like ʻole.
5. ʻO ka lāʻau lapaʻau ʻeleʻele ʻeleʻele e kōkua i ka hoʻohaʻahaʻa ʻana i ka friction i ka wā o ka wili ʻana, e hopena i nā hana wili ʻana a me ka liʻiliʻi o ke kūkulu ʻana i ka wela.
6. ʻO ka hui pū ʻana o ka hana kila kiʻekiʻe a me ka hoʻomaʻamaʻa ʻana i ka ʻili o ka ʻeleʻele e kōkua i ka hoʻokō ʻana i ka hana lōʻihi a hoʻemi i ke alapine hoʻololi.
