Qhov txawv ntawm SDS thiab HSS Drill Bits yog dab tsi?

Muaj ob lub tsev kawm ntawv xav txog SDS txhais li cas - nws yog slotted drive system, lossis nws los ntawm German 'stecken - drehen - sichern' - txhais ua 'insert - twist - secure'.

Txawm yog qhov twg yog qhov tseeb los xij - thiab nws tuaj yeem yog ob qho tib si, SDS txhais tau tias txoj kev uas lub laum ntsis txuas rau lub laum. Nws yog lo lus siv los piav qhia txog lub shank ntawm lub laum ntsis - lub shank txhais tau tias qhov ntawm lub laum ntsis uas tau khi rau hauv koj daim khoom siv. Muaj plaub hom SDS laum ntsis uas peb yuav piav qhia ntxiv tom qab.

HSS txhais tau tias yog hlau ceev ceev, uas yog cov khoom siv los ua cov ntsis laum. Cov ntsis laum HSS kuj muaj plaub lub duab sib txawv - ncaj, txo qis, tapered, thiab morse taper.

Qhov txawv ntawm HDD thiab SDS yog dab tsi?
Qhov sib txawv ntawm HSS thiab SDS laum ntsis yog hais txog yuav ua li cas lub laum ntsis raug chucked lossis fastened sab hauv lub laum.

Cov ntsis laum HSS siv tau nrog txhua lub chuck txheem. Lub laum HSS muaj ib lub shank puag ncig ntxig rau hauv lub laum thiab khaws cia rau hauv qhov chaw los ntawm peb lub puab tsaig uas nruj ib ncig ntawm lub shank.

Qhov zoo ntawm cov ntsis laum HSS yog tias lawv muaj ntau dua thiab siv tau rau ntau yam kev siv. Qhov tsis zoo tseem ceeb yog tias lub ntsis laum yooj yim xoob. Thaum siv, qhov kev co ua rau lub chuck xoob uas txhais tau tias tus neeg teb xov tooj yuav tsum nres thiab xyuas qhov khi, uas tuaj yeem cuam tshuam rau lub sijhawm ua tiav haujlwm.

Lub ntsis SDS tsis tas yuav tsum tau nruj. Nws tuaj yeem ntxig rau hauv qhov chaw uas tau teem tseg ntawm lub laum SDS yooj yim thiab du. Thaum siv, lub kaw lus qhov chaw tiv thaiv kev co kom tswj tau qhov ruaj khov ntawm qhov txuas.

DAB TSI YOG COV HOM SDS DRILL BITS UAS FEEM NTAU?
Cov hom SDS feem ntau yog:

SDS - tus SDS qub nrog cov shanks slotted.
SDS-Plus – hloov tau nrog cov ntsis laum SDS ib txwm muaj, muab kev sib txuas yooj yim dua. Nws muaj 10 hli shanks nrog plaub qhov uas tuav nws kom ruaj khov dua.
SDS-MAX – SDS Max muaj lub shank loj dua 18 hli nrog tsib qhov rau cov qhov loj dua. Nws tsis tuaj yeem hloov pauv nrog lub laum SDS thiab SDS PLUS.
Spline - Nws muaj lub shank loj dua 19 hli thiab cov splines uas tuav cov khoom nruj dua.
Rennie Tools muaj tag nrho cov khoom siv SDS uas muaj kev ua tau zoo tshaj plaws. Piv txwv li, nws cov khoom siv SDS Pus masonry hammer drill bits yog tsim los ntawm kev siv lub hau uas ua los ntawm sintered carbide uas tiv taus kev sib tsoo. Lawv zoo tagnrho rau kev tho cov pob zeb ua vaj tse, cov pob zeb thaiv, cov pob zeb ntuj, thiab cov cib khov lossis cov cib perforated. Kev siv yog ceev thiab yooj yim - lub shank haum rau hauv lub caij nplooj ntoos hlav yooj yim uas tsis tas yuav nruj, ua rau nws txav mus los zoo li lub piston thaum lub sijhawm tho. Qhov seem ntawm shank uas tsis yog lub voj voog tiv thaiv lub shank los ntawm kev tig thaum lub sijhawm ua haujlwm. Lub hammer ntawm lub laum ua haujlwm los ua kom tsuas yog lub shank nws tus kheej xwb, thiab tsis yog lub chuck loj, ua rau SDS shank dill bit ua haujlwm tau zoo dua li lwm hom shank.

Lub SDS Max Hammer Drill bit yog lub hammer drill bit uas tau tawv tag, muab ib qho ntawm cov kev ua tau zoo tshaj plaws muaj nyob rau hauv kev ua lag luam. Lub drill bit no tau ua tiav nrog lub taub hau tungsten carbide rau qhov kawg ntawm kev raug thiab lub zog. Vim tias lub SDS drill bit no tsuas yog haum rau cov tshuab drill uas muaj SDS max chuck, nws yog lub drill bit tshwj xeeb rau kev siv hnyav ntawm granite, concrete, thiab masonry.

COV DAIM NTAWV THOV ZOO TSHAJ PLAWS RAU HSS DRILL BITS
Cov ntsis laum HSS muaj ntau yam siv tau. Kev ua tau zoo dua thiab zoo dua yog ua tiav los ntawm kev ntxiv cov sib xyaw sib txawv kom muab kev ua tau zoo dua. Piv txwv li, Rennie Tools HSS Cobalt Jobber Drill Bits yog tsim los ntawm M35 alloyed HSS hlau nrog 5% Cobalt cov ntsiab lus, ua rau lawv nyuaj dua thiab tiv taus kev hnav ntau dua. Lawv muab qee qhov kev nqus dej thiab tuaj yeem siv rau hauv cov cuab yeej hluav taws xob tuav tes.

Lwm cov HSS Jobber Drills tiav nrog ib txheej oxide dub vim yog cov pa dej tempering. Qhov no pab kom cov cua sov thiab cov chip ntws tawm thiab muab cov khoom txias rau ntawm qhov chaw drilling. Cov khoom siv HSS drill bit no muab kev ua tau zoo tshaj plaws rau kev siv txhua hnub ntawm ntoo, hlau, thiab yas.
