High quality tricone rock bits for water well drilling

Product Detail

Tricone bit is made by steel body and teeth. The steel teeth tricone bit is also called milled teeth tricone rock bit. Milled teeth tricone bit is used for soft to medium hard rocks. 

Product name: Milled teeth tricone bit Material: Steel Process: Milling and maching Rock formation: Soft to medium hard rocks Application: Water well drilling and oil exploration Usage: Hole drilling IADC code: 116, 126,136, 216, 316, 346 Bearing type: Journal sealed bearing bit Size: 5 7/8" to 17 1/2"

Button bit is made by tungsten carbide teeth and steel. The tungsten carbide buttons is inserted to the drill bit head as the cutting teeth. It is used for hard rocks.
