Hex Shank Ntoo Spade Drill Bit nrog Tin Coated
Nta
1. Hex Shank Tsim: Cov laum khoom no muaj hexagonal shank uas tso cai rau kev teeb tsa sai thiab ruaj ntseg rau hauv lub laum chuck. Lub hex shank tsim muab lub zog tuav thiab tiv thaiv slippage thaum drilling, kom ruaj khov thiab precision.
2. Spade Shape: Hex shank ntoo spade laum khoom muaj ib tug spade-shaped txiav ntug. Qhov kev tsim no yuav pab tshem tawm cov khoom sai sai thiab tsim cov qhov hauv qab hauv qab ntawm cov ntoo yooj yim.
3.Tin Txheej: Cov laum khoom no muaj cov tin (titanium nitride) txheej ntawm lawv qhov chaw. Lub tin txheej muab ntau yam txiaj ntsig, suav nrog:
● Ntxiv Hardness: Cov tin txheej txhim khu lub hardness ntawm lub laum me ntsis, ua rau kev txhim kho durability thiab tsis kam hnav. Qhov no yuav pab kom lub neej ntev ntawm lub laum me ntsis, tshwj xeeb tshaj yog thaum drilling los ntawm cov ntaub ntawv nyuaj los yog abrasive.
● Txo kev sib txhuam: Cov tin txheej txo cov kev sib txhuam ntawm cov laum me ntsis thiab cov khoom siv tho, ua rau cov cua sov tsawg dua. Qhov no pab tiv thaiv me ntsis los ntawm overheating, uas yuav ua rau ntxov ntxov dulling thiab puas.
● Txhim kho Lubricity: Cov tin txheej txo cov kev sib txhuam thiab kev sib txhuam ntawm cov khoom siv laum rau ntawm lub laum me ntsis, tso cai rau kom smoother thiab huv si drilling. Nws kuj pab hauv nti khiav tawm, tiv thaiv kev txhaws thiab ua kom cov khoom tshem tawm tau zoo.
● Corrosion Resistance: Cov tin txheej muab cov txheej tiv thaiv uas tiv thaiv corrosion thiab oxidation, ua rau lub laum me ntsis haum rau siv nyob rau hauv ntau qhov chaw thiab ncua nws tag nrho lifespan.
