Product Q&A

Q:Which brands of hammers are compatible with your DHD shank bits?

Our DHD series bits strictly follow industry standard dimensions and are widely compatible with mainstream high, medium, and low air pressure DTH hammers.

Q:What is the expected service life of the drill bits?

Service life varies depending on rock hardness, operating parameters, and maintenance. Under normal conditions, our bits typically outperform the market average.

Q:Do you offer customization services for non-standard sizes?

Yes, our professional technical team can provide customized face designs and shank processing based on your specific drilling diameter and rock conditions.

Q:How to determine when a DHD bit needs regrinding or replacement?

If you notice a significant drop in penetration rate, poor flushing, or abnormal wear like eccentric wear or broken buttons, timely inspection is required. Minor wear can be reground, while severe damage requires replacement.

Q:What is your Minimum Order Quantity (MOQ)?

Standard models usually have a low MOQ, and some hot-selling specifications support small trial orders. Please contact our sales team for real-time quotes.
