6 Ways to Extend the Life of Your Diamond Core Drill Bits!

Apr 21, 2025

If you want to achieve efficient and profitable drilling operations, it is essential to extend the life of your drill bits as much as possible. The following six effective methods can help you achieve this goal.

Assume that the average life of a drill bit is about 125 meters. In this case, if you drill 1,000 meters, you can expect to need to replace the drill bit 8 times. If you extend the life of the drill bit by 15%, you can expect to replace one drill bit less. The deeper the hole, the more time you save. At a hole depth of 800 to 1,000 meters, it takes 4 hours to replace a drill bit. The following 6 tips can help you extend the life of your drill bit by an additional 15%.

1. Choose the right drill bit according to the hardness of the rock you are drilling.

For example, we have a variety of concrete core drill bits and stone core drill bits. ChinShine concrete diamond core drill bits have excellent cutting performance and long working life, suitable for wet use.

The hardness of rock formations is measured on the Mohs hardness scale, a chart of the relative hardness of various minerals. It is expressed in tens from 1-10. 1 is the softest and 10 is the hardest. The drill bit base is designed to perform best within a specific rock grade range, so you need to choose a drill bit that is suitable for the formation hardness you encounter. There are tools that can help you identify the hardness of the formation, such as etching kits or scratch tests.

2. Use drilling fluid additives.

Reducing torque can extend the life of equipment and tools. Choose environmentally friendly and safe drilling fluid additives that can be used alone or in combination with other additives to lubricate, reduce drill pipe wear and rust, and cool the drill bit.

3. Choose the right waterway configuration.

The waterway configuration should be considered based on the conditions encountered.

4. Determine the water flow rate.

Make sure the water flow to the drill bit is appropriate and sufficient. Make sure your drill pipe is not leaking oil. The right flow and pressure at the drill bit face will ensure that the cuttings are flushed clean and the drill bit is cooled.

5. Choose a high core drill bit.

High core drill bits can get longer penetration before changing the drill bit, which is especially important in deep hole construction.

6.Use drill bit core materials that match the formation type.
