PDC(Polycrystalline diamond compact )
Cutters DesriptionName: PDC
CuttersMeterial:PDC(Polycrystalline Diamond
Compoiste)Diameter:13mm, 16mm, 19mmDrilling Tool: PDC Drill
Bits, PDC ReamersIndustries:Oil drilling, Mining, stone
cuttingType: Flat face, Convex face, helmet face, ridge face, half
cut type.PDC- Polycrystalline diamond compact is composed of
polycrystalline diamond layer and tungsten carbide substrate, the
polycrystalline diamond layer possesses extremely high hardness and
abrasion resistance whereas the tungsten carbide substrate would
greatly improve the malleability and weld ability of the whole
composite, the polycrystalline diamond compost is used oil well
drilling petroleum, geology exploring, coalfield mining and
mechanical industry.Polycrystalline diamond compost (PDC) cutter
inserts for drilling suitable for soft to hard geological terrane
according to customers' demand we can offer polycrystalline diamond
compact with claw structures and chamfer types whether or not
grinding and polishing.Polycrystalline diamond compact (PDC) cutter
inserts for tools is suitable alloy non-metal and metal with high
rigidity. According to the customers' demand, we can offer
different shapes PDC cutters, such as flat face, convex face,
helmet face, ridge face, half cut type is avalible. The height of
diamond layer is different for different application.PDC cutters
for geological mining field drilling bits series are designed for
markets in the pursuing of cost. This series PDC are mainly used
for producing anchor-shank drill bits, which are equipped with
sharp edge, fast footage, high effectiveness, stability, economical
and practical
advantages.Available:ItemDimensiontypeDiameterHeightDiamondthicknessDiamondchamferCarbidechamfer08088.2±0.03mm8.2±0.03mm2.0±0.02mm0.3mmX45°0.5mmX45°100810±0.03mm8.2±0.03mm2.0±0.02mm0.3mmX45°0.5mmX45°130413.4±0.05mm4.5±0.03mm2.0±0.02mm0.3mmX45°0.5mmX45°130813.4±0.05mm13.4±0.03mm2.0±0.02mm0.3mmX45°0.5mmX45°131313.4±0.05mm13.4±0.03mm2.0±0.02mm0.3mmX45°0.5mmX45°160815.9±0.05mm15.9±0.05mm2.0±0.02mm0.3mmX45°0.5mmX45°161315.9±0.05mm15.9±0.05mm2.0±0.02mm0.3mmX45°0.5mmX45°190815.9±0.05mm15.9±0.05mm2.0±0.02mm0.3mmX45°0.5mmX45°191319.1±0.05mm15.9±0.05mm2.0±0.02mm0.3mmX45°0.5mmX45°191619.1±0.05mm15.9±0.05mm2.0±0.02mm0.3mmX45°0.5mmX45° Feature:1.
Super high hardness;2. Strong impact resistance and abrasion
resistance;3. High working efficiency, smooth surface4. Fast
drilling speed and long working life Application:1. For stone
quarrying, especially marble 2. For oil, coal, well drilling 3. For
street drilling 4. For Geological exploration How to choose large
cutters and small cutters:Large cutters(16-19mm) are more
aggressive than small cutters(8-13mm). However, they may increase
torque fluctuations. For production, small cutters are easy to make
excellent quality, but large cutters may not, there are many
factors to influence the quality. Smaller cutters (8mm, 10mm, 13mm)
are very sharp, have been shown to drill at higher ROP than large
cutters in certain applications. One exampled application is
limestone. Also, bit design employing smaller cutters have a higher
cutter density to enable them to withstand higher impact loading.
Additionally, small cutters produce smaller cuttings while large
cutters produce larger cuttings. Large cuttings may cause problems
with hole cleaning if the drilling fluid cannot carry the cuttings
up the annulus. Generally speaking, we have consistant quality no
matter for small cutters or large cutters, especially for large
cutters, our 16mm can be competed with E6 quality, and 19mm cutters
can be compared with USS quality. /* March 10, 2023 17:59:20
