Steel tooth tricone drill bit with high efficiency has strong wear resistant teeth and fast ROP, bit can work more stably, which is more suitable for drilling in soft or middle soft formations.

11 5/8" steel tooth drill bit / water well drilling bit

Steel tooth tricone bits or named as milled tooth rock bits, can be called as MT rock bits which are manufactured with superior quality steel and advanced technologies, designed for use with compressed air or fluid circulation systems. Steel tooth bit surface apply welding new wear-resisting material in keeping Mining Bit high mechanical drilling rate at the same time, improve the bit cutting tooth life. It is widely used in soft to medium formation for water well drilling.

Steel tooth tricone drill bits have very high drilling rates in soft formations. Lockheed 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.

11 5/8" steel tooth drill bit / water well drilling bit (OIL FIELD, MINING & WATERWELL) 

Steel tooth tricone drill bits can be retipped & built up with hard tungsten. Steel tooth tricone bits have very high drilling rates in soft and medium-soft formations. Lockheed can hard face steel teeth so that they sharpen themselves while drilling. Sealedbearing mill tooth tricone bits come with or without gauge protection.

Both open bearing and sealed bearing Mill Tooth Tricone Roller cone bit can come with or without gauge protection & skirttail protection.
