Re-Run Carbide Insert Tricone Drill Bits
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.
Contact a us for additional details about our complete line of
re-run carbide insert tricone drill bit product offerings.
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. Hole Products 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.
