The continuous necessity of deeper waterwells has requested more powerful drilling machines with torque capacity up to 3000 Kg.m. For this reason, it is extremely necessary to employ drill pipes that can withstand very strong torsional stress.

Drill collars are heavy drill string members used as weight thus forcing the bit to penetrate the formation being drilled. The collars are made from selected bars of chromium molybdenum alloy steel AISI 4145 H bored by trepanning to ensure close tolerance of bore alignment. All drill collars are full length heat trated to obtain the best physical properties and to provide a combination of hardness strength and ductility.
