Iyaziwa ngokuba nencam eyongezelelweyo yokusika, i-DIN 1869 HSS drill yenzelwe ukugrumba umngxuma onzulu. Olu qheliso lwenziwa kwizinto ezikumgangatho ophezulu we-HSS (M35, M2, 4341) ukuqinisekisa ukuqina kunye nokuzinza kwexesha elide lokusebenza. Inzuzo yobude be-bit ivumela ukuba igqwese ekuqhubeni umngxuma onzulu, ukuphatha imisebenzi enzima kunye neyokubhobhoza enzulu ngokulula.
I-drill yenzelwe i-135 ° yokusika ngokukhawuleza, engaphuculi nje ukuchaneka kokugaya, kodwa iyanciphisa "ukuhamba" okanye "ukutshintsha" kwe-drill bit ngexesha lokugaya, ukuqinisekisa inkqubo echanekileyo nechanekileyo. Umgangatho we-118 ° i-tip shape ifanelekile kuluhlu olubanzi lwezixhobo kwaye inikezela uluhlu olubanzi lwezicelo.
I-drill ifanelekile kwizinto ezithambileyo ezifana ne-aluminiyam, iinkuni, kunye neeplastiki, kodwa iyakwazi ukugrumba ngokufanelekileyo kwizinto ezinzima ezifana nentsimbi kunye nentsimbi. Ngamanqaku abo okugaya achanekileyo, i-grooves kunye nobukhulu be-drill, i-DIN 1869 drills inoluhlu olubanzi lwezicelo kwiindidi zemisebenzi yezoshishino kunye nezorhwebo.
I-drills ifumaneka kwiindidi ezahlukeneyo zokugqiba umphezulu, ezingagcini nje ukwandisa ukubonakala kwe-drill, kodwa kunye nokubola kwayo kunye nokuxhatshazwa kokugqoka. Ezi mpawu zidibanisa i-aesthetics kunye nokusebenza, ukuvumela ukuba ii-drill bits zigcine ukusebenza kwazo kuluhlu olubanzi lweendawo zokusebenza.
Ukuguquguquka kweebhithi ze-drill kubonakaliswa ngokufaneleka kwazo kuluhlu olubanzi lwezixhobo kunye nokusetyenziswa. Zifaneleke ngokukodwa kwizicelo ezifuna ukugrunjwa okuchanekileyo kubunzulu obungafikelelekiyo okanye kwiindawo ezivaliweyo. Uyilo lwabo olongezelelweyo ixesha elide aluphuculi kuphela ukukwazi ukubhobhoza kwizinto ezinzulu, kodwa kwenza kube lula ukusebenza kwii-angles ezikhethekileyo okanye izikhundla. Nokuba ufaka imibhobho kunye neengcingo okanye uqhuba ulwakhiwo oluntsonkothileyo kunye nemisebenzi yobunjineli, i-DIN 1869 drills inikezela ngokugqwesileyo. I-DIN 1869 drills yenziwe ngemigangatho engqongqo yolawulo lomgangatho, iqinisekisa ukuba i-drill nganye igcina ukusebenza kwayo kwiindawo ezahlukeneyo ezifuna ngamandla.
