Fa'atatauga
Tricone bits, lea e mafai foi e nisi ona ta'ua o piila cone bits po o tri-cone bits, e tolu cones.E mafai ona vili ta'ito'atasi keni ta'itasi pe a fa'avili e le manoa vili le tino o le pu.O cones o loʻo i ai ala taʻavale e faʻapipiʻiina i le taimi o le faʻapotopotoga.E mafai ona fa'aoga u'amea ta'avale e vili ai so'o se fa'avae pe a filifilia le tipi sa'o, fa'alava, ma fa'aumu.

1. O le malosi ma le ofuina o mea faʻapipiʻi e faʻaleleia atili e ala i le faʻaogaina o mea faʻapipiʻi carbide ma le malosi maualuga ma le maualuga o le ofuina o le ofuina.
2. Lau'ele'ele o le maualuga sa'o tu'uina vevela togafitia e ala i le fa'aogaina o togafitiga vevela fa'asolosolo e fa'aleleia ai le gafatia o le uta ma le ola tautua o le fa'amomoli.
3. O le ola tautua o le fa'alava e fa'alautele atili e ala i le fa'aaogaina o mea e sili atu ona faigata ma sili atu ona fa'alava mo le fa'aosoina.
4. O lenei fa'asologa o suau'u vaieli papa fa'aoga fa'amaufa'ailoga fa'apipi'i fa'apipi'i fausaga.Faatasi ai ma taʻavale ua faʻatulagaina i totonu o tootoo o loʻo faʻamau i totonu o le tino o le cone, ua faʻatuputeleina le tele o le tusi talaaga faʻamau.
6. E faigata ona fa'asaga i luga o mea e fa'aoso ai ma fa'aogaina i tekinolosi fa'aitiitiga fa'afefe.
7. E fa'aaoga e fa'amau fa'amau fa'ata'avalevale le fa'amaufa'ailoga.Fa'asagaga malō fa'aulu fo'i luga.O lo'o fa'apipi'i le fa'a'ofu'u fa'atasi i mea fa'aitiitiga fa'aitiitiga ona fa'apipi'i lea i le siliva.O le gafatia o le uta ma le faoa faamalosi o le faʻatauga e matua faʻaleleia.
