Frequently Asked Questions

What is the difference between DTH and Top Hammer drilling?

DTH (Down The Hole) drilling places the hammer at the bottom of the hole, delivering high impact energy directly to the bit. Top Hammer uses a surface-mounted hammer, suitable for shorter holes and softer formations.

Do you offer custom drilling solutions?

Yes, ROSCHEN GROUP provides OEM and ODM services. We can customize drill bits, hammers, rods, and complete systems based on your specifications and geological conditions.

What certifications do your products have?

Our manufacturing facility is ISO9001 certified. All products undergo strict quality control, including material testing, hardness checks, and performance validation.
