How to use button bits correctly

In rock drilling operations, the quality of button bits directly impacts drilling efficiency and service life. To maximize performance and durability, button bits must be used and maintained correctly. While the rock drill serves as the power source, the button bit is the primary contact point with the rock, making its proper use crucial.

Best Practices for Using Button Bits

1. Monitor the Wear Surface Regularly

• Inspect the button bit surface frequently. If signs of chipping, cracking, or excessive wear appear, perform timely grinding and repair to extend its lifespan.

• Worn button bits significantly reduce drilling speed, making regular maintenance essential for sustained performance.

2. Avoid Excessive Force & Ensure Proper Cooling

• Do not apply brute force during operation, as excessive thrust can cause premature failure of the button bit.

• Reduce propulsion force to minimize stress and impact damage.

• Use a continuous water flow to wash away debris and impurities, preventing overheating and potential thermal cracking of the bit.
