Pehea e koho ai i nā ʻāpana drill kūpono?

2. Nā ʻano wili ʻana:
Hele mai nā ʻāpana Drill i nā ʻano like ʻole, i hoʻolālā ʻia kēlā me kēia no nā noi kikoʻī. Eia kekahi mau mea maʻamau āu e ʻike ai:

- Nā ʻAi ʻAi ʻImi ʻAha: He kūpono no ka ʻoki ʻana i nā lua nui-diameter, hoʻohana maʻamau ʻia nā ʻāpana ʻike lua i ka paipu a i ʻole nā ​​mea uila.

3. Ka nui a me ke ʻano Shank:
Hiki mai nā ʻāpana drill ma nā ʻano nui, ana ʻia i nā hakina a i ʻole millimeters. ʻO ka nui āu e koho ai e pili ana i ke anawaena puka e pono ai no kāu papahana. Eia hou, pono ʻoe e noʻonoʻo i ke ʻano shank o nā pahu drill, ka mea e hoʻoholo ai i ka kūlike me kāu drill. ʻAe ka hapa nui o nā drill i nā ʻāpana shank poepoe, akā makemake kekahi i nā shanks hexagonal a i ʻole SDS. E hōʻoia i ka pili ʻana o nā pahu drill i koho ʻia me kāu drill e pale aku i nā pilikia pili.

4. Ka maikaʻi a me ka lōʻihi:
He mea nui ka hoʻokomo ʻana i nā bit drill kiʻekiʻe e hōʻoia i ka lōʻihi a me ka hana.
