1. O paipa vili uaea e faia i paipa u'amea fa'apitonu'u fa'apitoa ma le malosi maualuga ma le malosi o a'afiaga;
2. E mafai ona tatou suppl uaea vili tootoo ma AQ, BQ, NQ, HQ, PQ, AW, BW, NW, HW, HWT, PW, PWT ma isi vaa longyear tulaga masani lapopoa ma 1.5m, 3 mita umi;
3. Se'i vagana ai paipa vili, matou te tu'uina atu fo'i fa'ama'i impregnated core bits, casing shoe, reaming shells etc.

U85 AUS16NB maina koale vili vili e faia e 42CrMo ma YG11C carbide tips.
e fa'aaogaina lautele i le la'uina o koale i lalo o le eleele. Fa'aaogā mea mata'utia ma fa'agaioiga gaosiga fa'apitoa e gaosia.
Lelei lelei ma faiga fa'atonu lelei e maua ai le ta'uleleia lelei oa tatou vaega.

Tydrillbits o lo'o tu'uina atu fasi vili auala fa'atasi ai ma pito tungsten carbide.
O le carbide faʻaaogaina YG8, YG11C poʻo le fefaʻatauaʻiga. Bit tino faʻaaogaina 42 CrMo sila. E sili atu nai lo le 7 tausaga le poto masani o le tuʻuina atu o ituaiga vili bits.

1308 Spherical PDC Cutters faʻaaogaina le pauta taimane ma le tungsten carbide substrates e fai ma ana meafaitino,
o se mea lavelave lea e faia i lalo o le vevela maualuga ma le sintering maualuga maualuga.
Faʻafesoʻotaʻi le maʻaʻa, faʻafefe-teteʻe ma le faʻavevelaina o le vevela ma le maualuga o le malosi ma le malosi o le tungsten carbide.
