Hacksaws feem ntau yog siv los ntawm cov khoom siv los txiav cov hlau puag ncig, Lub kaum sab xis steel, cov hlau tiaj tus thiab cov khoom ua haujlwm me me. Hacksaw muaj xws li saw thav duab (feem ntau hu ua saw hneev) thiab saw hniav ob ntu, thaum siv, cov saw saw yog ntsia rau ntawm cov saw ncej, feem ntau cov hniav hau yog ntsia rau pem hauv ntej ntawm saw hniav, tab sis yog hais tias nws yog ib qho yooj yim mus use. adz, cov hniav hau yuav raug ntsia rau hauv lawv cov kev taw qhia, tuaj yeem txo qhov adz thiab ua kom lub neej ntev ntawm cov saw hniav. Lub hacksaw hniav yuav tsum tau muab tshem tawm los yog lub nro cov txiv ntseej loosened tom qab siv, thiaj li tiv thaiv lub deformation ntawm saw thav duab, yog li prolonging lub neej kev pab cuam ntawm lub saw ncej. Lub saw hniav muaj ob hom ntawm cov hniav unilateral thiab ob sab hniav, thiab tuaj yeem muab faib ua cov hniav ntxhib (14 hniav / 25mm), cov hniav nruab nrab (18 ~ 24 hniav / 25mm) thiab cov hniav zoo (32 hniav / 25mm), yog li ntawd. yuav haum rau sawing ntawm cov khoom sib txawv. Txhawm rau txhim kho kev ua haujlwm zoo thiab tsis txhob adz hniav, pom txiav cov khoom nyuaj xaiv ntawm cov hniav zoo nkauj, pom txiav cov khoom muag xaiv ntawm cov hniav ntxhib hniav, pom txiav cov khoom xaiv ntawm nruab nrab hniav saw hniav. Pom hniav thickness 0.5 ~ 0.65mm, dav 10 ~ 12mm, ntev ntawm 200mm, 250mm, 300mm peb specifications,
