Nozzles for Flushing.
Above features are subject to changes and modifications according
to customers' requirements.
The Diamond PDC drill bit designed to run at high penetration rates
even in applications that call for higher blade and cutter counts.
Its unique cutting structure layout adds another dimension to bit
stability and smooth running by combining the penetration rate
potential of traditional "single set" cutter layouts with the life
extending features of a "plural set" cutter layout. The result is a
bit that runs up to 20 percent faster than conventional PDC bits
with minimum bit wear.
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.
