Mill Tooth Tricone Bits

Mill tooth tricone drill bits have very high drilling rates in soft formations. Western Drilling Tools can hard face the milled teeth so that they sharpen themselves while drilling. Milled tooth tricone bits are designed for very soft to medium hardness formations.

Sealed Bearing mill tooth tri cone bit with or without gauge protection

These are the best preforming and longest lasting style of tri cone on the market. Gauge protection increases the life of the drill bit.

Open Bearing mill tooth Tri-Cone roller cone bit can come with or without gauge protection

These are less expensive then sealed bearing but they typically do not last as long.
