Пневматическое трехшарошечное роликовое долото, 9 резцов Caterpillar 6127698

The 9 Bit Air Tricone Roller Bit is designed to penetrate different hard formations encountered in mining, oil and gas exploration, and water well drilling. Consisting of three cone-shaped rollers equipped with durable tungsten carbide inserts, this bit employs a rolling motion to pulverize rocks. Each cone rotates independently, distributing the cutting force evenly across the surface for enhanced efficiency and durability. This innovative design enables the bit to adapt to changing geological conditions, providing optimal drilling performance even in challenging environments.Attributes:• Three-cone design.• 166 number of cutters.• Main cutter shape is conical.• Gauge cutter shape is ovoid.• Heel cutter shape is round.• Air back pressure ranges from 0.2 to 0.4 megapascal.• Rotary speed ranges from 60 to 90 revolutions per minute.• Weight on the bit ranges from 160 to 280 kilonewtons.• Consists of air-cooled bearing.Applications: The 9 Bit Air Tricone Roller Bit is used in drilling rigs for drilling operations to penetrate hard rock formations deep underground, providing optimal drilling performance even in challenging environments.
