concave drag bits
Product description:
PDC concave drill bit is a kind of full-scale drilling bit, which is mainly used in coal mine, mining, geological exploration, water conservancy and hydropower, highway, railway, bridge and construction.
Types:
YHA/YHB /YHC series Classified By PDC cutters
Ordinary type—YHC Series with ordinary Ployscrystalline Diamond Compact cutters
Reinforced type—YHB Series with Series Grade B quaity reinforced cutters
Super strength type—YHA Series with Grade A quality Super good PDC cutters
Classified by Body material type
Matrix body
Steel Body (45号钢或者切削部分YG11刀片合金)
PDC stands for Polycrystalline Diamond Compact which refers to the cutters on these drill bits. PDC bits have exceptional rates of penetration when drilling and can out perform other bits in the right conditions.
The diamond cutters are 10 times stronger than steel but they are Brittle and can get damaged in discontinuous formations.
PDC bits love to drill through shale’s, salty clay stone, concrete and sands. Avoid gravel and sand stone.
PDC Bits a are an excellent choice for expensive or very deep wells and particularly excel when drilling in soft to medium hard formations.
PDC bits can be constructed from steel bodies or matrix bodies.
You will get a deeper hole out of a Matrix Body but they cannot be repaired or retipped they may crack if the driller dynamically impacts the bit.
A steel body PDC bit is much tougher than a matrix body and will not crack. It will not drill quite as deep but it can be repaired and retipped.
Applications:
PDC concave drill bit is a kind of full-scale drilling bit, which is mainly used in coal mine, mining, geological exploration, water conservancy and hydropower, highway, railway, bridge and construction.
This drill bit is the first option to be applied in drilling complex formation with perfect stability, good drainage and fast penetration rate.
• Thread connection type:
API REG or customized female or male threads.
When drilling with ProDrill PDC bits it is important to know and our instructions for the recommended weight on the drill bit and to control the rotational speed.
drilling tools can supply PDC bits in sizes from 3.5” (88.9mm) to 121/4” (311.2 mm). Our PDC bits have 3 to 6 wings, Jet Nozzles and gauge protection.
also Builds PDC bits for RC drilling (reverse circulation drilling) applications.Sandard Sizes for Immediate Availability: 3″ to 12 1/4″ (76mm to 311mm)

PDC concave drill bits
The cutters made of Polycrystalline Diamond Compact with perfect durability and high drilling speed;
The breaking post made of YG11 alloy as it’s substrate, with high torsional strength and can break rock together with the cutters;
The gauge is made of YG8C alloy with perfect wear resistance. It can protect the bit from shrinking during the drilling process;
The size of the nozzles is 8mm~14mm. It can discharge debris at the same time cooling the cutter by using drill fluid;
