Wood chisels yog dab tsi?

	Feem ntau cov chisels ntoo yog tsim los ntawm ntau qhov chaw thiab tuaj yeem ua los ntawm ntau yam khoom siv nyob ntawm lawv lub hnub nyoog lossis lub hom phiaj. Hauv qab no yog cov lus qhia los pab koj txiav txim siab yam khoom twg yog qhov zoo tshaj rau koj.
Cov hniav
	Cov cuab yeej hlau Feem ntau cov ntoo chisel yog tsim los ntawm cov hlau hu ua cov cuab yeej steel (qee zaum hu ua "carbon steel"). Qhov sib ntxiv ntawm carbon rau hlau ua rau nws nyuaj dua li cov hlau tsis tu ncua, thiab muaj ntau theem ntawm hardness nyob ntawm seb lub hom phiaj ntawm lub cuab yeej yuav siv rau. Cov cuab yeej hlau feem ntau siv rau cov khoom muaj cov ntsiab lus carbon ntawm 0.60-0.75%.
	Vanadium hlau Cov hniav ntawm lwm cov ntoo chisels tuaj yeem ua los ntawm vanadium hlau. Los ntawm kev sib xyaw me me ntawm vanadium nrog cov hlau, qhov hardness tuaj yeem nce ntxiv, yog li nws feem ntau siv rau hauv kev tsim cov cuab yeej tsim nyog rau kev txiav cov dej num. Ntau cov cuab yeej phais, kais, tuag thiab chisels yog tsim los ntawm vanadium hlau nrog cov ntsiab lus vanadium ntawm 1-5%.
	Vanadium yog dab tsi? Vanadium yog ib qho tshuaj lom neeg hlau. Nws yog ib qho nyuaj, silvery grey hlau uas feem ntau alloyed nrog hlau los tsim cov cuab yeej muaj zog steels xws li kev kub ceev steel.
Kuav
	Hardwood handles Kev lig kev cai, tes tau ua los ntawm cov ntoo tawv xws li tshauv, beech, thiab boxwood. Hardwood handles yog siv vim lawv nyiam tuav, tuaj yeem tiv taus rauj ntau zaus, thiab tseem nqus tau qee qhov cuam tshuam los ntawm rauj tshuab los pab tiv thaiv cov hniav.
	yas tuav Ntau lub chisel tes yog tsim los ntawm cov yas hu ua polyvinyl chloride (los yog PVC luv luv). PVC yog qhov thib peb feem ntau cov yas tsim nyob rau hauv lub ntiaj teb no thiab yog siv rau chisel leeg vim hais tias nws yog ib qho kev cuam tshuam resistant thiab rated rau ntau rauj tshuab.
	Cov tes tuav Lub softgrip handles yog tsim los ntawm kev sib xyaw ntawm cov yas tawv thiab roj hmab. Lawv muab cov neeg siv nrog ib qho yooj yim, ruaj ntseg tuav thiab txo kev vibration thiab tes qaug zog.
ferrule
	Lub ferrule yog lub nplhaib hlau, feem ntau yog ua los ntawm cov hlau lossis tooj dag, uas txhawb nqa tus kov. Cov rings hlau no feem ntau pom ntawm shanked chisels vim tias lawv lub hom phiaj tseem ceeb yog los txo qhov tshwm sim ntawm kev sib cais. Yog xav paub ntxiv txog shanks, saib nplooj ntawv npe: Dab tsi yog shanks thiab sockets rau wood chisels?
kawg cap
	Qhov kawg ntawm cov ntoo chisel tuaj yeem ua los ntawm cov yas tawv xws li polyvinyl chloride (PVC) lossis hlau xws li hlau. Lub hau kawg yuav tsum muaj zog txaus los tiv thaiv rov qab rauj tshuab yam tsis muaj kev tawg.
