Regular inspection

Regular inspection is the first step in caring for and maintaining rock drill bits. The inspection content includes the wear of the drill bit, the integrity and looseness of the carbide buttons, etc. If any irregularities are detected, it is essential to promptly take measures for repair or replacement to prevent the issue from worsening. Additionally, it is advisable to inspect and maintain the rock drill bit after a specific period of use or upon completing a certain number of drilling operations.

Clean and lubricate

Cleaning and lubrication are critical aspects of maintaining rock drill bits. While drilling, the rock drill bit will encounter a substantial amount of dust and debris. These substances will adhere to the surface and inside of the drill bit, affecting its proper operation. Therefore, it is essential to meticulously clean the rock drill bit after each use, removing surface and internal debris. When cleaning, it is advisable to steer clear of highly corrosive cleaning agents to prevent any damage to the drill bit.

Rock drill bits require good lubrication to reduce friction and wear during operation. While in operation, it is crucial to regularly inspect the lubrication condition, ensuring that there is an adequate amount of clean lubricating oil or lubricant. If insufficient lubrication is detected, it is necessary to promptly replenish or replace the lubricant to maintain the drill bit’s proper operation.

Reasonable use

Proper use of rock drill bits is crucial to its care and maintenance. During drilling operations, it is essential to steer clear of overloading or subjecting the drill bit to excessive impact to prevent damage. Simultaneously, it is advisable to adhere to the manufacturer’s recommended usage parameters, including rotation speed and pressure, to minimize wear and prolong the service life of the drill bit. Furthermore, it is important to avoid using inappropriate rock drilling machinery to prevent unnecessary damage to the drill bit.

Storage and maintenance

Proper storage and maintenance of rock drill bits are equally crucial. When storing, it is significant to prevent exposure to moisture, high temperatures, or corrosive environments to avoid potential damage to the drill bit. At the same time, the drill bit should be stored in a dry and ventilated place to prevent moisture and rust. While in storage, it is essential to conduct regular inspections of the rock drill bits, addressing any corrosion or damage promptly when detected. Before reuse, the rock drill bits should undergo a comprehensive inspection and maintenance process to ensure their proper operation and optimal working performance.

Grinding and replacement

When the rock drill bit is seriously worn or damaged, it should be grinding or replaced in time. When grinding, it’s crucial to utilize professional grinding machines to ensure the quality and reliability of the process. If grinding is not possible or the cost is too high, we should replace the drill bit with a new one in time. When selecting a new drill bit, opt for a product with reliable quality and excellent performance to guarantee the smooth progression of the drilling operation.


Taking proper care of rock drill bits is crucial for extending their service life and enhancing work efficiency. By mastering these care and maintenance skills, we can effectively extend the service life of rock drill bits and improve work efficiency. During use, you should also pay attention to operational safety and follow safe operating procedures to ensure the safety of personnel and equipment. In addition, we recommend that you stay in touch with a reliable rock drill bit supplier so that you can always get the latest maintenance and upkeep recommendations as well as quality product and service support.
