Aero-CARB diamond coated drills are built for abrasive applications where hole quality, tool guidance and wear resistance all matter.
Designed for materials such as CFRP, graphite and aluminium silicon alloys, the range gives manufacturers practical drilling options for clean holes, stable positioning and more dependable performance across the job.
Whether you need double margin guidance, a 4 flute drill route, or a ballnose slot drill for shaped features, Exactaform can help match the tool to the material, hole and process.
Abrasive materials ask more from a drill.
The tool needs to enter cleanly, stay guided through the hole, manage wear and support the finish or tolerance the job needs to hold. In materials such as CFRP, graphite and aluminium silicon alloys, that combination matters.
Aero-CARB diamond coated drills bring together tool geometry, diamond coating and practical application support, giving teams a standard range to review for trial, repeat use or wider tooling evaluation.
Different drill styles exist because different applications need different behaviour.
The right option depends on the material, operation, tolerance, finish requirement and how the tool needs to behave in the process.
For drilling applications where guidance, hole roundness and controlled positioning are priorities.
The double margin design helps support the drill through the hole, making this a strong route for abrasive materials where cleaner, more consistent holes matter.
Available in metric and imperial options.
Best fit: CFRP, graphite and aluminium silicon alloy drilling where guidance and repeatability are key.
For applications where a 4 flute diamond coated drill is the better fit for the material, hole requirement or machining conditions.
This option gives teams another Aero-CARB drill geometry to review where the application calls for it. The right choice depends on the material, hole size, machine setup and required outcome.
Best fit: applications where the material and setup point towards a 4 flute drill route.
For applications closer to slotting, profiling or contouring than standard holemaking.
These sit within the wider Aero-CARB advanced composite machining range and should be reviewed where shaped features, slotting or abrasive composite profile work are part of the job.
Best fit: abrasive composite slotting, profiling and shaped-feature applications.
Aero-CARB diamond coated drills are designed to help with the issues that matter most in abrasive drilling:
The value is not just the coating. It is the combination of geometry, coating, material fit and technical support.
Supported materials and starting data
Starting cutting data is available for selected Aero-CARB drilling applications across aluminium silicon alloys, multidirectional CFRP and graphite. This should be treated as a starting reference, with final parameters checked against the specific drill, material, machine setup and required outcome.
Material | Cutting Speed |
Aluminium 9% Si | 100–250 m/min |
Aluminium 13% Si | 80–150 m/min |
Aluminium 25% Si | 80–150 m/min |
CFRP multidirectional | 50–150 m/min |
Graphite | 60–600 m/min |
For aluminium alloys, soluble oil coolant is recommended. For CFRP and graphite, air blast helps remove chips and dust while reducing heat build-up in the flutes. On hole exit in CFRP and graphite, reducing feed by 30% is recommended to help manage breakout.
