Lub ntsiab lus tsim ntawm lub laum lub ntsis yog nws tus kheej-center, tiv thaiv kev txav thiab co, thiab txhim kho kev txiav thiab drilling ceev;lub twisted hniav tsim nrog sib sib zog nqus grooves tso cai rau nws mus tshem tawm cov chips thiab hais sai dua lwm yam xyaum, vim hais tias nws muaj ib tug self-center point.Thaum lub sij hawm txiav, cov txheej txheem txiav yog du thiab meej, ua rau kev tshem tawm cov nti zoo heev, uas ua rau cov txheej txheem txiav huv si thiab ruaj khov dua.

Lub laum me ntsis tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm qhov sib txawv.Raws li qhov tshwm sim ntawm nws ob txheej txheej kub titanium thiab dub nitride nto, nws muaj ntau dua qib ntawm lubrication retention, tso cai rau smoother drilling, thiab raws li qhov tshwm sim ntawm ob txheej txheej, cov roj nplua nyeem tau zoo dua ua ke, uas ua rau nws yooj yim dua. txhawm rau xyaum ua kom zoo dua.Raws li qhov tsis zoo ntawm cov cuab yeej siv tsis zoo, cov khoom siv laum coated yog ntau dua tiv taus corrosion thiab ya raws.

Nrog rau 1/2 "txo shank koj tuaj yeem siv nws nrog yuav luag txhua qhov kev xyaum xovxwm thiab cov cuab yeej siv hluav taws xob feem ntau ntawm kev ua lag luam, thiab nrog rau peb lub tiaj tus shank kawg koj yuav muaj peev xwm ua kom nws nruj dua thiab ruaj ntseg hauv lub puab tsaig triple chuck thiab tsis txhob muaj teeb meem thaum lub sij hawm machining los ntawm kev tshem tawm cov teeb meem thiab qhov muaj peev xwm ntawm slippage thaum lub sij hawm machining shanks yuav siv tau nrog ntau yam cuab yeej cuab tam thaum txiav nyob rau hauv lub counterclockwise kev taw qhia (txoj cai), lawv tshem tawm chips upwards los ntawm kev txiav, yog li tiv thaiv clogging.
