DTH DRILL BITS
DTH bits are used together with down‑the‑hole hammers, with impact energy delivered directly to the bit at the bottom of the hole for efficient and stable rock penetration. They are widely used in mining blast‑hole drilling, quarrying, water‑well drilling, foundation engineering and large‑diameter rock drilling applications.
