Product Q&A
Q:How can I tell if my DHD shank is worn out?
A:
Inspect the shank splines for rounding, cracking, or excessive wear. A worn shank can cause poor energy transfer and damage the hammer chuck.
Q:What causes premature button breakage?
A:
Premature breakage is often caused by drilling in fractured rock, excessive feed pressure, or using an incorrect face type for the formation.
Q:Do you provide a warranty for your DHD drill bits?
A:
We guarantee our bits are free from manufacturing defects. Performance-related issues are evaluated on a case-by-case basis by our technical team.
Q:Can I mix different face types in the same drilling operation?
A:
It is generally recommended to use the same face type consistently to maintain uniform hole diameter and optimal hammer performance.
Q:What information do you need to recommend the right bit?
A:
Please provide the hammer model, required hole size, rock type/hardness, and your primary goal (e.g., maximum speed vs. maximum life).
