Nws tuaj yeem hais meej meej tias aluminium sawb tsis tuaj yeem txiav stainless hlau. Raws li yog vim li cas, tus editor yuav qhia rau koj.
Aluminium yog mos thiab yooj yim rau lo rau riam, thaum stainless hlau yog ib qho nyuaj heev, txawm mus txog lub hardness ntawm qeb 4 steel.

Carbide thiab 6-10 degree rake lub kaum sab xis tsim yog zoo rau txhuas, tab sis qhov tsim no yog siv los txiav stainless hlau, tsis tsuas yog txiav tsis tau yog tias koj txav mus, nws yuav tawg koj cov hniav.
Rau kev txiav stainless hlau, cov neeg siv uas tsis tshua muaj yuav tsum tau feem ntau xaiv high-speed steel saw hniav. Tau kawg, cov neeg siv uas xav tau siab yuav kuj xaiv ceramic alloy saw hniav. Qhov kev ua tau zoo ntawm qhov tom kawg yog ntau dua li qhov qub, tab sis tib lub sijhawm, tus nqi kuj tseem yuav siab dua li qub. Yog li nws pom zoo kom koj xaiv raws li qhov xwm txheej tiag tiag.
