Frequently Asked Questions
What is DTH Hammer?
Down-the-hole drilling (DTH) 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.
What type of drill is best for stone?
Drilling through stone, brick, granite, and marble requires tough drill bits made of hard metal. Kingdrilling drill bits are specifically designed to tackle stone and can bore through these hard surfaces with ease.
Can you drill through cobblestone?
Cobble is extremely hard and very difficult to cut, making directional drilling challenging. During drilling, cobble pieces move and therefore rock bits cannot penetrate them effectively due to constant movement.
