We are one of the largest suppliers of drill bits in the industry with a team that has over 80 years combined experience in the oil, water, mining and HDD industries.The Waitman family name is synonymous with the drill bit industry. We started repairing milltooth bits in the 1950s and continued to evolve as drill bits changed with technology. The Waitmans have provided quality service and bits to their customers for years. Our extensive experience and knowledge, widespread network and vast inventory of bits available allow us to provide you with the best products and service in the industry.

Mill Tooth

Milled-tooth bits have steel tooth cutters, which are fabricated as parts of the bit cone. The bits cut or gouge formations out when they are being rotated. The teeth vary in size and shape, depending on the formation. We provide sizes ranging from 3" up to 36", sealed and open bearing.


Tungsten Carbide Insert (TCI) bits, also known as Button Bits, combine high ROP with durability and reliability, providing superior performance for drilling operations. With patented insert and cutter geometries, along with proprietary carbide materials, these roller cone bits offer many cutting structures that allow maximum mechanical energy to be applied to the formation We provide sizes ranging from 2 15/16" up to 30".

Hole Openers

A device used to enlarge the size of an existing borehole, having teeth arranged on its outside circumference to cut the formation as it rotates. We provide factory build MT and TCI 8" up to 36"
