Exactaform's diamond-coated tools are engineered for aerospace machining of advanced composites, CFRP and other highly abrasive materials, where standard carbide wears too quickly to hold quality across a full production run.
In aerospace, that wear rarely shows up as a single failure. It compounds: extra tool changes, hole quality that drifts, finish issues, rising inspection pressure and a process that becomes harder to predict. A CVD diamond-coated cutting edge stays sharp far longer in these materials, keeping holes cleaner, tool changes down and the process stable from the first part to the last.
The range covers diamond-coated end mills, finishing cutters and ball nose tools, plus our newly developed 2 Flute Double Margin Diamond Coated Drill, all built to outperform standard carbide in demanding aerospace applications.
Aero-CARB gives aerospace manufacturers diamond-coated tooling options for abrasive materials across drilling, roughing, finishing, ball-nose milling and slot drilling.
The right option depends on the material, operation, tolerance, finish requirement and how the tool needs to behave in the process.
New to the Aero-CARB Range, the 2 Flute Double Margin Diamond Coated Drill is built for abrasive drilling applications where standard carbide is not lasting long enough and process stability matters.
With new size options and diamond-coated wear resistance, it supports cleaner, more consistent holes in suitable aluminium silicon alloys, CFRP and graphite applications. The double margin design provides added guidance through the hole, helping manufacturers improve drilling confidence in demanding materials.
The Aero-CARB 2 Flute Double Margin Diamond Coated Drill is built for abrasive materials where standard carbide drills are not lasting long enough and the process needs cleaner, more consistent holes.
The double margin design supports guidance through the hole. The CVD diamond coating helps protect the cutting edge against abrasive wear. Together, they give aerospace teams a stronger drilling route for suitable CFRP, graphite and aluminium silicon alloy applications.
The current Aero-CARB cutting data supports selected aluminium silicon alloys, multidirectional CFRP and graphite. It includes starting cutting speeds, feed guidance by drill diameter and practical notes around coolant, air blast and feed reduction on hole exit.
For aluminium alloys, soluble oil coolant is recommended. For CFRP and graphite, air blast is recommended to remove chips and dust and help prevent heat build-up in the flutes. On hole exit in CFRP and graphite, the technical guidance recommends reducing feed by 30% to help eliminate breakout issues.
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 |
Aero-CARB can support aerospace applications involving:
Exactaform can support aerospace teams beyond the first tool enquiry, helping review the material, application, stock route, starting data and whether diamond-coated, carbide or PCD is the right answer.
For some teams, the immediate need is cleaner drilling in CFRP or aluminium silicon alloys. For others, it is reducing tool changes on an abrasive process. For procurement and quality teams, the priority may be confidence in supply, documentation and support before a tool is used more widely.
Exactaform has built its reputation on specialist tooling for demanding applications.
We support aerospace teams who need more than a catalogue answer. That means looking at the material, operation, tool path, tolerance, production requirement and commercial reality before recommending a route.
Aero-CARB gives customers a diamond-coated option for advanced composite and abrasive material machining. Our wider capability across PCD, carbide, diamond-coated tooling and specials means we can help you decide where the range fits and where another tooling solutions may be stronger.
That is what we mean by being your projects partner: looking at the job properly, telling it straight and helping you get the right tool for the work.
Made different, delivered better.
