PDC cutter profile for geometry and tolerance-controlled supply.
PRECISION-CONTROLLED DRILLING CUTTER
Fraise PDC de précision
Series: Precision Series
Precision PDC Cutter is a PDC cutting element for drilling, mining and engineering tools, supplied as a PCD diamond table bonded to a cemented-carbide substrate. Field Diamond controls size, chamfer and surface-finish requirements against the selected drawing so buyers can align pocket fit, cutter position, inspection records and repeat supply in one quotation.

APPLICATIONS & EQUIPMENT
Applications For Drilling, Mining And Engineering Tools
Match cutter geometry, diamond-table exposure and carbide-base interface to the bit position and formation.
01
Oil & Gas PDC Bits
Primary or gauge positions in tight oil and gas, shale, interbedded and deepwater formations; select flat or chamfered geometry with the bit designer.
02
Mining, Water & Geothermal Tools
Drilling tools where cutter geometry, diamond-table exposure and the carbide-base interface are matched to hard rock, abrasive rock and the designed cutting path.
03
OEM, Retrofit & Replacement Supply
Submit the pocket drawing, nominal size, chamfer, material stack, quantity and inspection requirements for a comparable custom or replacement quotation.
TECHNICAL DRAWING
Release Dimensions Against A Controlled Revision.
Use the reference drawing view to start a discussion; final geometry, datums and tolerance are released against the buyer drawing revision.
Reference view for a 13 mm-class PDC cutter package; request the controlled drawing for the selected geometry.
Working mediumRock drilling with water, air or drilling-fluid circulation selected by the bit and formation.
Working temperatureUse the approved thermal window; quality screening includes 755°C, 780°C and 805°C test stages.
Pressure / loadSet WOB, RPM, impact exposure and hydraulics from the bit program; run a low-load break-in.
Installation limitsClean and align the base; braze at 670–730°C for 10–15 seconds, cool slowly and avoid water or oil quenching.
CUSTOMIZATION
Align The Cutter To The Pocket, Formation And Inspection Plan.
Share the drawing revision and target quantity so geometry, process route and acceptance records can be quoted together.

Packing label, sample quantity and inspection plan
USE & SAFETY
Install, Break In And Inspect With A Controlled Procedure.
Use trained personnel and the approved bit drawing and drilling program for the selected cutter geometry.
01
Before Brazing
Verify drawing revision, dimensions, chamfer and batch label. Clean the carbide base and bit brazing face with acetone or alcohol for 2–4 hours, or use an ultrasonic cleaner.
02
Brazing And Cooling
Use Bag-24 silver-based braze at 670–730°C for 10–15 seconds. Align the cutter in the pocket and cool slowly in an insulated box; do not water-quench or oil-quench.
03
Break-In And First Contact
Stop about 0.2–0.3 m above hole bottom, circulate flushing fluid or air, then make first contact at 30–60 rpm. Run 1–2 tonnes at low WOB or the corresponding start load over 0.2–1 m before full load.
04
Inspection And Storage
Inspect after brazing and break-in for cracks, delamination, abnormal edge damage and pocket movement. Keep unused cutters dry, protected from impact and traceable to drawing revision and batch.
Important safety noticeUse eye and heat protection, ventilation and thermal isolation during brazing. Isolate rotation, pressure and hydraulic energy before inspection or replacement. Do not treat test temperatures or reference dimensions as a universal operating rating; use the approved bit program and drawing.
