Frequently Asked Questions
What is top hammer drilling?
In top hammer drilling, percussive force is generated at the top of the drill string and transmitted through drill rods to the bit, making it ideal for shallow to medium depth drilling operations.
Top hammer drilling vs down-the-hole drilling?
The primary difference is hammer placement - top hammer has the hammer at the top of the drill string, while DTH places the hammer down-the-hole at the bit.
How does top hammer drilling work?
Hydraulic drilling rigs generate percussive force transmitted through shank adaptors and drill pipes to the bit, while air compressors handle dust removal and slagging.
