FAQ
Q1: What materials are your drilling bits made of?
A: Our down‑the‑hole bits and top‑hammer drill bits adopt high‑strength alloy steel and premium tungsten carbide inserts. Strict heat treatment improves wear resistance for hard rock, granite, and well‑drilling construction.
Q2: Can your bits fit my existing drilling rig and hammer?
A: We cover mainstream industry thread specifications for top hammer bits and shank adapters. Our DTH bits match common DTH hammers. Just share your rig model or hammer size, and we will check compatibility for free.
Q3: Will you offer discounts for large‑quantity purchases?
A: Our factory‑direct quotation keeps a competitive base price. Quantity discount and combined‑order preferential terms are available.
Q4: How are drill bits packed for long‑distance sea shipment?
A: Every drill bit gets anti‑rust oil and plastic‑film wrapping. Goods are arranged inside IPPC‑fumigated wooden cases, fastened by steel straps to avoid collision during transit.
Q5: Which trade terms do you support?
A: EXW, FOB, CIF, and DAP deliveries are supported.
Q6: What factors decide the service life of DTH drill bits?
A: Rock hardness, drilling depth, air pressure, lubrication condition, and straightness of the borehole will affect the wear speed of tungsten‑carbide buttons. We can send you an operation manual to extend bit lifespan.
Q7: What kind of rock‑drilling scenarios suit top‑hammer bits?
A: Top‑hammer bits are ideal for shallow hole, quarry, rock‑bolting, and road‑construction drilling. DTH bits perform better for deep water‑well drilling and extremely hard rock.
Q8: Do you provide a a quality warranty?
A: Every batch undergoes strict inspection before delivery. We provide free replacement for defects caused by manufacturing.
