kingpdc supplies flat, cutting-edge shaped and triangular PDC cutters with sample, dimension and inspection options for bit makers sourcing a consistent manufacturing partner. Cutter face, diameter, height and chamfer determine fit for the bit position and formation. Each cutter combines diamond and carbide within a complete drill bit.
kingpdc supplies the flat, cutting-edge shaped and triangular families shown below. Flat cutters provide a conventional shear face; the inclined-edge form changes outer-edge contact, while the triangular form uses three inclined faces for changing rock contact. Each family has its own product page and size table.
Wuhan Field Diamond Co., Ltd. supports samples, customer-specific chamfers and grade discussions. For a repeat order, send the cutter family, nominal diameter and height, diamond-table thickness, target bit position and expected quantity. The agreed dimensions and inspection route then define the production specification.
A flat cutter is the baseline when the bit layout calls for a broad planar shearing face. The cutting-edge design adds an inclined plane at the outer contour and is offered for directional drilling and shale gas bit positions. The triangular face has three inclined surfaces and is offered for interbedded and hard-formation duties.
Geometry alone does not determine the result. Cutter diameter governs pocket fit, height affects planned exposure, and chamfer influences initial edge strength. Flat models span 8.00–19.05 mm (0.315–0.750 in) diameter; the two shaped series span 13.44–19.05 mm (0.529–0.750 in). A shaped face also has a specified orientation and bit position.
A polycrystalline diamond table forms the wear-facing cutting surface. A tungsten carbide substrate supports the table and provides the body used for mounting in the bit pocket. The interface between them and the edge chamfer are part of the cutter specification.
A PDC cutter is one cutting element, not a complete drill bit. The bit maker still determines blade layout, pocket position, exposure and hydraulics. A cutter drawing should state the outer dimensions and working-face orientation so that a shaped element is installed in the intended direction.
This selected range covers flat and two shaped PDC cutter families for drill-bit manufacture. Their working faces, nominal diameters, chamfers and intended bit positions distinguish the three options.
Oil and gas, water-well and coal-mine bits; dimensions and cutting face are listed for bit-drawing comparison.
Directional drilling and shale gas bits; dimensions and cutting face are listed for bit-drawing comparison.
Interbedded or hard formation bits; dimensions and cutting face are listed for bit-drawing comparison.
Sample trials, pilot batches and scheduled production runs serve different order volumes. Each quotation states the cutter specification, quantity, unit price and dispatch window.
Sample trial: one matched sample set; quote per design; dispatch 7–14 working days after specification approval.
Pilot order: 50–499 cutters per specification; priced per piece; 2–4 weeks after sample approval.
Repeat supply: 500+ cutters per specification; volume quote per piece and scheduled replenishment.
Made to order; standard production window 2–4 weeks after approved drawing and order confirmation.
Export shipping by air or sea with agreed Incoterms and destination paperwork.
Commercial invoice, packing list and agreed dimensional inspection report.
These answers cover cutter fit, material construction, samples and inspection for a first order.
Formation, cutter position and bit pocket define the selection. A flat face suits conventional shearing layouts; the inclined-edge and three-face options offer different contact patterns. A geometry review uses target diameter, height, exposure and orientation.
The selected families include diameters from 8.00 to 19.05 mm (0.315 to 0.750 in). Flat and cutting-edge series list 2.0, 2.5 or 3.0 mm (0.079, 0.098 or 0.118 in) diamond tables; triangular models list a 2.8 mm (0.110 in) table.
Yes. A sample request can specify the cutter family, nominal dimensions, grade, quantity and planned drilling duty. Trial results can then guide the production specification.
Dimension inspection and internal-integrity checks are available for agreed specifications. The order records the model, tolerances, sample quantity and report content.
No. The cutter is the diamond-faced element mounted in the bit body. Blade placement, pocket geometry, hydraulics and the finished bit are separate parts of the drilling-tool design.
