Tricone Drill Bits

The cost of a good drill bit varies from about 1-5% of the total cost, however, the drill bit will affect up to 75% of your total cost.

  • Reducing the number of times you trip
  • Increased rate of penetration when drilling means more holes faster
  • Straighter holes and longer bit life
  • Saves you time and money

The Tricone Bit is the most versatile drill bit on the market. It is the go to drill bit in most styles of drilling. Whether you are drilling a water well or an oil well, Total Drilling Solutions has the Tri Cone Drill Bit for you.

The Advantages of Using a Tricone over Other Drill Bits

  • There is a Tricone suitable for any rock formation
  • Tricone bit is versatile and can handle changing formations
  • Tricones are reasonably priced, long lasting and have an efficient drilling rate


Depending on your application, Total Drilling Solutions can provide you with new, re-run or premium oil field quality Tricone bits. The difference between a premium oil field Tricone bit and non-premium oil well quality Tricone is that the roller cones have high end sealed bearings; extremely high quality tungsten carbide and diamond gauge protection throughout the drill bit as well as skirt tail hard facing and optimized hydraulics. These roller cone drill bits are designed to go to extreme depths in extreme conditions and in situations where they cannot fail.

When ordering a bit, the IADC bit classification system is a very useful tool and allows TDS to specify a bit that out performs your expectations.

The TCI Tricone Bit ranges in size from 3.875” (88.9mm) to 28” (711.2mm). The Mill Tooth Tricone Bit ranges in size from 5” (127mm to 32” (812.8mm)

4 character code, first 3 characters are numbers, the last is a letter

  • 1st number is the series. 1 to 3 represent a milled tooth tri cones, 4 – 8 represent TCI tri cones. The higher the series number the harder more abrasive the rock formation is.
  • 2nd number is the relative degree of hardness within a series. The number ranges from 1 – 4, the higher the number the harder the formation
  • 3rd number represents bearing design and gauge protection
    • Open bearing
    • Roller bearing air cooled
    • Open bearing gauge protected
    • Sealed roller bearing
    • Sealed roller bearing gauge protected
    • Sealed friction bearing--Sealed friction bearing gauge protected
  • 4th character is a letter and describes optional features. There are 16 alphabetic character’s, each representing the Tricones most significant feature.
