Description
Solid PCD drills are considered for abrasive CFRP and compatible material stacks where fibre breakout, delamination and bore-exit condition must be controlled. The drill geometry and cutting data need to match the exact stack sequence rather than CFRP alone.
Where is this drill commonly reviewed?
- CFRP components with defined entry and exit requirements
- CFRP and aluminium stacks
- CFRP and titanium stacks after the heat, chip and edge-load conditions are reviewed
- Composite assemblies using a machine, drill unit, robot or other controlled setup
What changes the drill design?
- Material sequence, grade and thickness of every layer
- Hole diameter, tolerance, countersink or stepped features
- Acceptable fibre breakout, delamination, burr and bore-exit condition
- Machine or drill-unit rigidity, runout, workholding and backing support
- Dry or coolant-assisted process, chip or dust removal, and current cutting data
Stack-material boundary: a geometry that works for CFRP and aluminium may not be suitable for CFRP and titanium. The metal layer changes chip formation, heat input and cutting-edge load, so the complete stack must be reviewed.
Factory preparation and inspection
Depending on the design, the factory route can include slotting or flute generation, edge preparation and sharpening, precision grinding, magnified inspection, and a review for repair or reconditioning. The route is selected from the drill geometry and stack application.
Questions buyers usually ask
Can the same PCD drill be used for every CFRP stack?
No. Stack sequence, metal layer, thickness, exit condition and drilling setup can require a different point and edge geometry.
What defect information should be shared?
Photographs of entry and exit damage, delamination, burrs, fibre breakout, hole-wall condition and tool wear help define the problem before a new design is reviewed.
What application data is needed for an RFQ?
Please send the drawing, full stack sequence and thickness, hole requirements, machine or drill-unit details, workholding, coolant or dry condition, current tool and cutting data.
Request an application review
Send the stack drawing and current defect information through the Full RFQ form. For related composite-cutting tools, see PCD Tools.
