17.5 in. GTX TCI Tricone Drill Bit, IADC 535
Description:
The group of Roschen GT™, GTX™, GX™ and STX™ tricone drill bits from Robert Roschen has accumulated significant field experience over the last decade, becoming the drill bits of choice for many operators and contractors in a variety of applications. These bits are built upon field-proven technologies, using high-quality materials and a superior manufacturing processes to provide reliable and consistent drilling performance.
Applications:
. Conventional drilling applications
. Rotary and motor applications
Features/Benefits:
. GTX Bearing - The GTX line features an O-ring sealed ball and roller bearing. These bits are recommended for high rpm drilling and directional applications where hole sections and hours on bit are reduced.
. Maximum Penetration - Aggressive drilling action because of very large cone offset and deep intermesh tooth design with good ventilation.
. Center Jet - A fourth jet is positioned in the center of the bit and utilized to prevent bit balling and the associated reduction in penetration rate.
