Tapered HSS twist Drill Bit with black oxide Finish
Likaroloana
1. High Speed Speel (HSS) kaho
2.Moetso oa Tapered:
3.The black oxide holim'a phekolo
4.Lisebelisoa tsena tsa ho phunya li etselitsoe hore li lumellane le lisebelisoa tse fapaneng tsa ho cheka, ho fana ka boiketlo ba tšebeliso le mekhoa e mengata bakeng sa lisebelisoa tse fapaneng tsa mechine.
Ka kakaretso, HSS twist drill drill bit e nang le black oxide finish e fana ka nako e telele, ho nepahala, ho hanyetsa kutu, le ho feto-fetoha ha maemo, ho e etsa sesebelisoa sa bohlokoa bakeng sa litlhoko tse fapaneng tsa ho cheka.
BONTŠA SEHLAHISO
Melemo
1.Ho hanyetsa mocheso: Lisebelisoa tsa tšepe tse phahameng ka lebelo le phahameng li ka mamella mocheso o phahameng o hlahisoang nakong ea ho cheka, ho fokotsa kotsi ea ho chesa le ho boloka katleho ea ho itšeha.
2.Precision Drilling: Moqapi oa tapered o lumella ho lumellana hantle le ho nepahala, ho etsa hore e be se loketseng bakeng sa ho etsa likoti tse nepahetseng ka thepa e sa tšoaneng.
3.Moqapi oa lekolilo la spiral o khothalletsa ho tlosoa ha li-chip ka katleho, ho fokotsa kotsi ea ho koala le ho ntlafatsa ts'ebetso ea ho cheka.
4.The tapered HSS twist drill bit with black oxide coating e loketse ho phunya lisebelisoa tse sa tšoaneng tse akarelletsang tšepe, lehong, polasetiki le metsoako, ho fana ka mefuta-futa ea likopo tse fapaneng.
5.The black oxide surface treatment e thusa ho fokotsa likhohlano nakong ea ho phunya, e leng se etsang hore ho be le ts'ebetso e bonolo ea ho phunya le ho fokotsa mocheso o fokolang.
6.Motsoako oa kaho ea tšepe e phahameng ka potlako le phekolo ea holim'a oxide e ntšo e thusa ho finyella ts'ebetso ea nako e telele le ho fokotsa maqhubu a ho fetola lisebelisoa.
