BQ NQ HQ PQ Reaming Shell

Product Description
The drill bit is connected to the diamond reaming shell, enabling simultaneous drilling and side grinding. However, it is crucial to maintain a drilling distance equal to or greater than the drill bit diameter (reaming) to prevent premature wear on the drill bit's outer diameter. Moreover, this practice also helps in avoiding hole wall vibrations and deformations. To reiterate, the diamond reaming shell facilitates drilling and side grinding simultaneously while ensuring the preservation of the drill bit's effectiveness.

The core tube sits snugly between the drill bit and the diamond reaming shell, with its diameter slightly smaller than that of the reaming shell.

Main Functions and Features
To ensure that the hole diameter remains in line with the design requirements, it is necessary to modify the wall of the hole. This will significantly reduce the amount of work required to clean the hole under the new bit. By making this adjustment, you can save time and effort during the drilling process while still ensuring that the hole meets the required specifications. Taking these steps will help to increase efficiency and improve overall productivity. So, it is important to focus on maintaining the proper diameter of the hole to avoid any potential issues down the line.
The passage of drilling fluids is effectively facilitated by the helical type reaming shell. Its design ensures a smooth and efficient flow for the fluids during drilling operations.
Ensuring that the drilling tools remain stable while operating at high speeds in the hole is crucial. It is important to maintain their functionality and reliability while drilling to avoid any complications or accidents. Therefore, proper steps must be taken to ensure that the tools are in good working condition before and during drilling operations. It is essential to employ effective maintenance procedures to prevent any damage or malfunctions that could compromise the stability of the drilling tools. Only when the tools are in optimal condition can they operate safely and effectively in the hole at high speeds.
* Extend the drill bit's life.
The service life of the matrix is long, and it is resistant to wear and tear. In fact, it is so durable that its wear-proof feature guarantees its longevity. When it comes to the matrix, you can rely on its longevity and resistance to wear, ensuring that it will serve you for a long time.
