Changing tooling in aerospace needs a clear reason and a controlled path in.
The Aero-CARB 2 Flute Double Margin Diamond Coated Drill is a CVD diamond-coated carbide drill designed for abrasive drilling applications in materials such as CFRP, graphite and aluminium-silicon alloys. It gives aerospace teams a standard diamond-coated option to review and trial against their current process.
It has been developed for applications where the process needs cleaner, more consistent holes and practical tool-life support.
The wider Aero-CARB range also includes 4 Flute Diamond Coated Drills, 2 Flute Double Margin Diamond Coated Drills, 10° Helix Diamond Coated Endmills, Roughing Endmills, Finishing Endmills and ballnose tools.
Key features include:
2 flute double margin design to support drill guidance and hole roundness
90° point angle to support accurate hole positioning
CVD diamond coating for wear resistance in abrasive materials
H6 shank tolerance for controlled tool holding
Metric range from Ø3.00 mm to Ø12.00 mm
Starting cutting data available for selected materials and drill diameters
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 | Feed mm/rev | Drill Diameter 3 mm | Feed mm/rev | Drill Diameter 6 mm | Feed mm/rev | Drill Diameter 9 mm | Feed mm/rev | Drill Diameter 12 mm |
Aluminium 9% Si | 100–250 m/min | 0.04 | 0.06 | 0.1 | 0.12 |
Aluminium 13% Si | 80–150 m/min | 0.02 | 0.03 | 0.05 | 0.07 |
Aluminium 25% Si | 80–150 m/min | 0.01 | 0.02 | 0.03 | 0.05 |
CFRP multidirectional | 50–150 m/min | 0.02 | 0.03 | 0.05 | 0.08 |
Graphite | 60–600 m/min | 0.02 | 0.04 | 0.08 | 0.12 |
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.
We can help your team move from tooling review to a sensible next step.
The starting point is simple: share the material, hole size, machine setup and what your current tool is not giving you.
Aero-CARB diamond-coated drills are most relevant where abrasive materials, hole quality and tool wear need to be reviewed together.
Typical applications may include:
For work involving slotting, profiling or contouring, another Aero-CARB tool may be more suitable. For high-volume repeat production, PCD may still be the stronger long-term route.
