Frequently Asked Questions

How long is the service life of the drill bit?

Our high-performance DTH drill bits are designed to enhance drilling efficiency and durability. Service life varies based on rock hardness and operating conditions, but typically exceeds standard bits by 20-40%.

What are the differences between DTH and ordinary drill bits?

DTH (Down-The-Hole) bits operate with a hammer at the bottom of the hole, delivering direct impact force for deeper and faster drilling. Ordinary bits rely on surface rotation and are less efficient in hard rock.

What materials are used in detonating cords?

High-quality detonating cords are made from high-conductivity copper or copper composite materials, ensuring reliable signal transmission and resistance to environmental stress.

Can gas bags reduce blasting vibrations?

Yes, KUANGBAO self-inflating gas bags help mitigate blasting vibrations by providing consistent borehole sealing, improving energy distribution and reducing ground shock.
