Sebenzisa ngesarha yokubuyiselana nge-1/2 ye-intshi ye-universal shank system.Umphezulu we-S 644 D ubonelela ngokugoba okucocekileyo kunye nokugawula iinkuni.Amazinyo ayo okusila abukhali anokufikelela ekusikeni okungenazinyembezi.Ukongezelela, umzimba owenziwe ngokupheleleyo we-saw blade uvumela ukufikelela lula kwiindawo ekunzima ukufikelela kuzo kwaye kwenza ukusika okugobileyo kwenzeke.Incakuba inencam etsolo kwaye yenzelwe ngokukhethekileyo iibhleyidi zeplunge.Yenziwe nge-HCS (i-High Carbon Steel) kwaye ifanelekile ukusika umthi othambileyo, ukhuni lokwakha kunye nazo zonke izinto ezingenakunqongophala kwizicelo zokwakha.Isarha ye-S 644DF enzima inokusika iinkuni kunye nentsimbi ngokukhawuleza.I-saw blade ine-wide tapered body (22 mm) kunye ne-extra-thick material (1.6 mm) ukugcina ukuzinza kokugqibela okufunekayo kwizicelo zokudiliza, ukuvumela ukusika okulawulwayo ngaphandle kokugoba.Idizayini yayo yezinyo eguquguqukayo kunye ne-groove yezinyo enkulu inokususa ngokufanelekileyo izinto kunye nokuxhasa inkqubela phambili yomsebenzi ngokukhawuleza.I-HSS eqinile ngokupheleleyo (i-high-speed steel) i-rack ye-blade yenziwe nge-BIM (i-bimetal) kwaye idibene ne-elastic HCS (i-high carbon steel) i-blade, efanelekileyo kakhulu ukusika iindawo zetsimbi ezilinganayo ezifakwe emthini..S 922 AF Flexible inokusika isinyithi ngokulula.Inowuthi yayo entle kakhulu kunye namazinyo angama-wavy avumela ukusika okugudileyo kwezinto ezibhityileyo.Ukongezelela, i-BIM (i-bimetal) i-blade yenziwe ngokucophelela ukufezekisa ubomi obude benkonzo xa usika insimbi yamandla eqhelekileyo.Ixhotywe nge-pitch enhle kakhulu (1 mm) yokusika iipayipi zetsimbi kunye neeprofayili ezinobunzima be-0.7 mm ukuya kwi-3 mm.Ubude obuqhelekileyo be-saw blade yokubuyisela i-150 mm, kwaye umthamo omkhulu wokusika ngu-100 mm.I-S 922 VF Flexible inokusika umthi kunye nentsimbi ngokulula.Ijiyometri yezinyo eguquguqukayo yenza ukusika okugudileyo kunye nokungcangcazela okuncitshisiweyo.Ukongezelela, izinto ezisemgangathweni eziqhelekileyo (0.9 mm) kunye nobude be-blade zibonelela ngezakhono ezigqwesileyo zokusika.I-BIM (i-bimetal) i-blade ilungiselelwe ukusika izikhonkwane ezithambileyo, izixhobo zetsimbi eziphantsi kwekhabhoni kunye neengxenye zetsimbi ezingenayo i-ferrous ezifakwe emthini.Ubude obuqhelekileyo bala ma-saw blades (150 mm), umthamo omkhulu wokusika ngu-100 mm.
