Cais
Darnau Tricone, y gall rhai hefyd eu galw'n ddarnau côn rholio neu ddarnau tri-côn, Y darn côn rholer yw'r offeryn a ddefnyddir fwyaf mewn drilio petrolewm a drilio daearegol.Mae gan bit Tricone y swyddogaeth o effeithio, malu a chneifio creigiau wrth ffurfio, felly gall addasu i ffurfiant meddal, canolig a chaled.Gellir rhannu'r darn côn yn bit côn melino (dannedd dur) a bit côn TCI yn ôl y math o ddannedd.
Nodweddion
1. triniaeth wres tymheredd uchel meithrin.
2. Mae dannedd carbid â chryfder a chaledwch uchel yn gweithio'n fwy effeithlon.
3. wyneb weldio caled gwefus palmwydd dannedd gydag aloi caled, Atal traul a gwisgo'r darn dril yn effeithiol.
4. Pennaeth amddiffyn OD i leihau traul pen yn effeithiol yn ffurfio sgraffiniol ac ymestyn gwaith bit.
Mae jet 5.Directional yn ehangu ardal llif ochrol a glanhau twll gwaelod defnyddiol a chynyddu ROP.
6. system iro amddiffyn o gofio a selio system o did ymestyn bywyd gwaith did.
7. Cysylltiad API REG.
