FAQ:

1. What is DTH hammer?

Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.

2. What type of drill is best for stone?

Drilling through stone, brick, granite, and even marble is possible, but it takes a tough drill bit made of hard metal to do it. Kingdrilling drill bits are specifically designed to tackle stone and can bore through these hard surfaces with ease.

3. Can you drill through cobblestone?

Because cobble is so hard and challenging to cut, directional drilling is challenging. Cobble fragments roll away and do not stay in place during drilling because they are constantly moving and make it impossible for rock fragments to pierce them.
