Q

A special device that, when fitted into the rotary table, transmits torque to the kelly and simultaneously permits vertical movement of the kelly to make the hole is called a __________.

🔍 Key Concepts

• Function of the rotary table in drilling operations • How torque is transmitted to the kelly while allowing it to move vertically • Difference between bushings, slips, and master bushings in drilling equipment

💭 Think About

• Which component actually contacts the kelly to turn it, and at the same time allows it to move up and down? • Which listed parts are mainly for support or holding, rather than for transmitting torque while permitting vertical motion? • Think about which item is specifically sized or shaped to match the kelly itself.

✅ Before You Answer

• Verify which device is designed to fit in the rotary table and interface directly with the kelly • Confirm which item’s main purpose is to transmit torque rather than just support or hold the drill string • Eliminate any option that mainly serves as a holding/slipping device rather than a torque‑transmitting guide
