Auger feem ntau laum cov qhov khov kho qhov nrog cov sab smoother thiab tsawg dua. Lawv feem ntau yog siv rau cov ntoo hluav taws xob dav dav hauv kev tsim kho, ntoo hauv kev ua teb, thiab ntau lwm daim teb. Spade kav muaj cov sab rougher thiab yog li ntawd siv rau cov cheeb tsam uas yuav tau them rau. Piv txwv li, cov rooj zaum no feem ntau siv thaum txhim kho hluav taws xob conduit lossis kav dej los ntawm ib lub phab ntsa, raws li lub qhov yuav tau npog nrog kev ua tiav zoo.

Kev tsim qauv yog qhov sib txawv tseem ceeb ntawm ob qho no. Lub auger me ntsis yog ib txoj kev helical laum nrog ib cov xov kab ntxeev ntawm sab xub ntiag thiab ob txoj kev chisels ntawm txhua qhov taub. Cov chisels no yog lub luag haujlwm rau kev npaj ntoo. Spade cov khoom yog tiaj. Lawv xav tau kev tsim qauv zoo li, zoo li tus duav lossis duav, nrog ob daim di ncauj ntse rau txhua qhov kawg thiab cov lus qhia tsis ua tiav.

Auger xav tau qhov qis qis thaum drilling, ua rau lawv xis nyob dua. Qhov ntxeev ntawm cov xov rub tawm lub laum nqes thiab tsim ib qho kev tsav tsheb tsis siv neeg tsav tsheb uas ua haujlwm tam sim ntawd, txawm tias nws tsuas yog lub laum lub nra hnyav. Spade cov khoom ntim yuav muaj cov lus qhia ntse, tab sis lawv tsis muaj xov, yog li lawv tsis tsav lawv tus kheej. Yog li koj xav kom khawb nrawm nrog ntau dua sab hauv qab. Siv tsuas yog thauj tau ntawm cov laum me ntsis, drilling tuaj yeem siv sijhawm luv.

Vim yog cov qauv kev ntseeg siab, eter yog qhov tsim nyog rau kev ntsuas kev drilling. Qhov no qhia tau hais tias lawv yuav khawb ib lub qhov ntawm qhov dav sib npaug thaum txiav ncaj qha lossis ntawm lub kaum sab xis. Cov xov ntxeev kom khov kho tom rau hauv ntoo kom tsum tsis txhob txav, cia kom muaj kev txiav heev. Spade cov khoom noj muaj rau cov kev cai drilles cov duab thiab ntau thiab tsawg. Lub cuab tam tau yooj yim kho lub kaum sab xis ntawm thaum pib lossis drilling, uas tso cai rau koj los ua qhov me dua / loj dua hauv qhov dav dua ib rab ntsej muag.
