In the world of rock drilling, the "hidden cost" that kills your project budget isn't the fuel or the labor—it’s the premature disposal of DTH button bits. When buttons show signs of wear, many operators are quick to replace them with new ones. But did you know that you are likely throwing away 50% to 70% of your bit's potential life?

At Panda Equipment, we’ve analyzed countless worn-out tools from job sites. Today, we’re sharing three expert maintenance tips to help you extend bit life and significantly lower your operating costs.

1. Identify Wear Before It Becomes Critical

The most common mistake is waiting for the carbide buttons to become completely flat or heavily fractured before sharpening. Once the buttons lose their original profile, the drilling speed drops, and the bit is forced to work harder, generating excessive heat that damages the steel body.

• Expert Tip: Establish a regular inspection schedule. As soon as you notice minor wear, it’s time for maintenance. It is far cheaper to sharpen a bit than to replace it entirely.

2. Timely Re-sharpening is the Key to Efficiency

Think of your DTH bit like a professional cutting tool. If you wait until it is dull, you have to use twice the force to drill, which makes the tool prone to breaking.

• The Benefit: Proper, timely re-sharpening restores the original button profile, ensuring maximum rock-breaking efficiency. A sharp bit drills faster, puts less strain on your DTH hammer, and consumes significantly less fuel.

3. Invest in the Right Grinding Equipment

Manual sharpening or using improper tools can damage the carbide inserts, leading to micro-cracks that shorten the bit's lifespan even further. Using professional, purpose-built grinding equipment ensures consistency and precision, which is essential for high-performance drilling.
