He aha ka hammer drill?

Ma ke kamaʻilio ʻana e pili ana i nā ʻāpana hammer drill bit, e hoʻomaopopo mua kākou i ke ʻano o ka hāmare uila?

Hoʻokumu ʻia ka hāmare uila ma luna o kahi drill uila a hoʻohui i kahi piston me kahi koʻokoʻo hoʻohui crankshaft i hoʻokele ʻia e kahi kaʻa uila. Hoʻopiʻi ia i ka ea i hope a i waho i loko o ka cylinder, e hoʻololi i ka manawa o ke kaomi ea i loko o ka cylinder. Ke hoʻololi nei ke kaomi ʻana o ka ea, hoʻihoʻi ka hāmare i loko o ka cylinder, ua like ia me ka hoʻohana ʻana i ka hāmare e paʻi mau ai i kahi bit drill rotating. Hiki ke hoʻohana ʻia nā ʻāpana hammer drill ma nā ʻāpana haʻahaʻa no ka mea e hoʻopuka ana lākou i ka neʻe wikiwiki (ka hopena pinepine) ma ka paipu drill i ka wā e huli ai. ʻAʻole makemake nui i ka hana lima, a hiki iā ia ke wili i nā lua i loko o ka sima a me ka pōhaku, akā ʻaʻole metala, lāʻau, plastik a me nā mea ʻē aʻe.

ʻO ka hemahema ʻo ia ka nui o ka haʻalulu a e hoʻopōʻino i nā hale a puni. No nā kaola kila i loko o ka hale paʻa, ʻaʻole hiki ke hele mālie nā pahu drill maʻamau, a ʻo ka haʻalulu e lawe mai i ka lepo he nui, a ʻo ka haʻalulu e hoʻopuka i ka leo nui. ʻO ka lawe ʻole ʻana i nā lako pale pono hiki ke pilikia i ke olakino.

He aha ka hammer drill bit? Hiki ke hoʻokaʻawale ʻia lākou e nā ʻano lima ʻelua: SDS Plus a me Sds Max.

SDS-Plus - ʻElua lua a me ʻelua mau ʻauʻau poʻo

ʻO ka ʻōnaehana SDS i hoʻomohala ʻia e BOSCH i ka makahiki 1975 ke kumu o ka nui o nā hammer drill bit i kēia lā. ʻAʻole ʻike hou ʻia ke ʻano o ka drill bit SDS kumu. Ua hoʻomohala pū ʻia ka ʻōnaehana SDS-Plus kaulana i kēia manawa e Bosch a me Hilti. ʻO ka unuhi maʻamau ʻo "Spannen durch System" (pūnaewele hoʻololi wikiwiki), ua lawe ʻia kona inoa mai ka huaʻōlelo Kelemania "S tecken - D rehen - Palekana".

ʻO ka nani o ka SDS Plus ʻo ia ʻoe e hoʻolei wale i ka drill bit i loko o ka pūnāwai pahu puna. ʻAʻole pono ka hoʻopaʻa ʻana. ʻAʻole paʻa paʻa ka drill bit i ka chuck, akā paheʻe i hope a i waho e like me ka piston. Ke kaʻapuni ʻana, ʻaʻole e paheʻe ka bit drill i waho o ka pahu me ka mahalo i nā dimples ʻelua ma ka shank mea hana poepoe. ʻOi aku ka maikaʻi o nā puʻupuʻu shank drill SDS no nā hammer drill ma mua o nā ʻano ʻokoʻa ʻē aʻe o nā ʻāpana shank drill ma muli o ko lākou mau ʻāpana ʻelua, e ʻae ai i ka hammer kiʻekiʻe kiʻekiʻe a me ka maikaʻi o ka hammering. ʻO ka mea nui, hiki ke hoʻopili ʻia nā ʻāpana hammer drill i hoʻohana ʻia no ka ʻeli ʻana i ka hāmare i ka pōhaku a me ka ʻuala i kahi ʻōnaehana shank a me ka pahu piha i hana ʻia no kēia kumu. ʻO ka ʻōnaehana hoʻokuʻu wikiwiki SDS ke ʻano hoʻopili maʻamau no nā ʻāpana hammer drill o kēia lā. ʻAʻole wale ia e hāʻawi i kahi ala wikiwiki, maʻalahi a palekana hoʻi e hoʻopaʻa i ka bit drill, e hōʻoiaʻiʻo nō hoʻi ia i ka hoʻoili mana maikaʻi loa i ka drill bit ponoʻī.

SDS-Max - ʻElima mau lua pōʻai puni

Loaʻa iā SDS-Plus nā palena. ʻO ka mea maʻamau, ʻo ke anawaena o ka SDS Plus he 10mm, no laila ʻaʻole pilikia ka ʻeli ʻana i nā lua liʻiliʻi a me waena. I ka ʻeli ʻana i nā lua nui a hohonu paha, ʻaʻole lawa ka torque hiki ke hoʻopaʻa i ka bit drill a haki ka lima i ka wā e hana ai. Ua hoʻomohala ʻo BOSCH i ka SDS-MAX e pili ana i ka SDS-Plus, nona ʻekolu mau ʻāpana a me ʻelua lua. ʻElima mau ʻauwaʻa ko ka lima o ka SDS Max. ʻEkolu puka hāmama a ʻelua puka pani (e pale i ka lele ʻana o ka drill bit). ʻIke maʻamau ʻo ia ʻekolu mau ʻauwaʻa a me ʻelua lua poʻe lima lima, ʻike ʻia hoʻi ʻo ʻelima mau lua pōʻai lima. He 18 mm ke anawaena o ka lima SDS Max a ʻoi aku ka maikaʻi o ka hana kaumaha ma mua o ka lima SDS-Plus. No laila, ʻoi aku ka ikaika o ka lima SDS Max ma mua o ka SDS-Plus a ua kūpono ia no ka hoʻohana ʻana i nā ʻāpana drill hopena ʻoi aku ke anawaena no nā hana lua nui a hohonu. Nui nā poʻe i manaʻoʻiʻo e hoʻololi ka ʻōnaehana SDS Max i ka ʻōnaehana SDS kahiko. ʻO ka ʻoiaʻiʻo, ʻo ka hoʻomaikaʻi nui ʻana i ka ʻōnaehana ʻo ka piston ka lōʻihi o ka hahau ʻana, no laila ke pā ʻo ia i ka drill bit, ʻoi aku ka ikaika o ka hopena a ʻoi aku ka maikaʻi o ka ʻoki ʻana o ka drill bit. ʻOiai ka hoʻonui ʻana i ka ʻōnaehana SDS, e hoʻohana mau ʻia ka ʻōnaehana SDS-Plus. ʻO ke anawaena shank 18mm o SDS-MAX ka hopena i nā kumukūʻai kiʻekiʻe ke hana ʻia nā nui drill liʻiliʻi. ʻAʻole hiki ke ʻōlelo ʻia he pani no SDS-Plus, akā he mea hoʻohui. Hoʻohana ʻokoʻa nā hāmare uila a me nā drill ma waho. Aia nā ʻano lima ʻokoʻa a me nā mea hana mana no nā paona hāmare like ʻole a me ka nui drill bit.

Ma muli o ka mākeke, ʻo SDS-plus ka mea maʻamau a hoʻokomo maʻamau i nā pahu drill mai 4 mm a 30 mm (5/32 in. a 1-1/4 in.). Ka lōʻihi o 110mm, ka lōʻihi loa 1500mm. Hoʻohana pinepine ʻia ʻo SDS-MAX no nā lua nui a me nā koho. Ma waena o 1/2 iniha (13 mm) a me 1-3/4 ʻīniha (44 mm) nā bit drill impact. ʻO ka lōʻihi holoʻokoʻa he 12 a 21 iniha (300 a 530 mm).
