IADC 537 Tungsten Carbide Tricone Roller Drill bits 9 7/8 inch for Hard Rock Formation Water Well Drilling
Roschen offers a complete line of tricone drill bits. Tricone bits are available in new and used (re-tip and re-run) steel tooth and tungsten carbide insert, in sizes from 2 1/2 to 36, for use in all formations, with any bearing/seal type, and with a wide range of additional custom features.
New Tricone Drill Bits
Roschen offers new steel tooth and tungsten carbide insert (tci) tricone bits in sizes from 2 1/2" – 36", with open or sealed bearings, regular or jet circulation, and a wide range of additional custom features for ideal performance in any formation. Tricone bits can be customized to optimize penetration rates and bit life in particular formations and under specific operating weights and rotation speeds.
Tricone rotary bits are sometimes a good alternative to a DTH hammer. Available in TCI (carbide buttons) and mill tooth configurations.
We carry a large inventory of rerun bits and can also supply new bits. TCI bits are available for Medium Soft, Medium Hard, and Hard formations. Please call us to check stock.
Remember, when drilling with Tricone Bits you need to maintain proper down pressure to prevent premature bearing failure

Re-Tip Steel Tooth Tricone Drill Bits
Re-tip steel tooth tricone bits are gently used bits that usually come from the oil fields. They are refurbished for use in non-oilfield rotary applications, such as water wells, HDD, and construction type drilling. These bits offer significant cost savings over new bits. Roschen offers a wide range of premium, oil field quality re-tip steel tooth bits in sizes ranging from 2 1/2" to 36". Re-tip bits are available for use in soft, medium, and hard formations.

Re-run carbide insert bits are used bits that have been re-worked, cleaned, and often times painted. Re-runs offer significant cost savings over new carbide insert bits. Roschen offers a variety of re-run carbide bits in sizes ranging from 2 1/2" to 36". All re-runs are premium quality and available for use in soft, medium, and hard formations.
