2. PDC ADVANTAGES
PDC Drill Bits are equipped with Hardened Alloy Steel base
material;High performance PDC-Cutters;Carbide and Diamond gauge
protection;Carbide/Diamond Shock Studs;Threaded or Plain Carbide
Nozzles for Flushing.
Above features are subject to changes and modifications according to customers' requirements.
Diamond bits work across an extended range of weight on bit,
penetrating quickly even at low bit weights in softer rock. When
formations firm up, the bits can take added weight with a smooth
torque response and maintain higher than competitive rates of
penetration. The technology is a departure from traditional plural
set bits that require higher weights to drill even in soft rock,
and are generally durable, but slow, even in harder rock.
Traditional plural set bits also can produce an erratic torque
response when taking additional weight.
We have rich experience in this field of Roller Tricone Bits, PDC
Drill Bits, Oil Drilling Toosl, Rock Drilling tools, DTH hammers
and bits for 60 years.
Owing to high quality, professional serivce and competitive price,
