Aero-CARB 2 Flute Double Margin Diamond Coated Drill

Cleaner Holes. Fewer Tool Changes.

The Aero-CARB 2 Flute Double Margin Diamond Coated Drill is designed for abrasive drilling applications.

Built with double margin geometry and a CVD diamond coating, it supports cleaner, more consistent holes in suitable materials such as CFRP, graphite and aluminium silicon alloys.

Available in metric sizes from Ø3.00 mm to Ø12.00 mm, this drill gives manufacturers a practical diamond-coated route when hole quality, guidance and tool life all matter.

Key Benefits

Application flexibility: Suitable for aluminium, CFRP and abrasive non-ferrous drilling applications.
Maximum guidance: Double margin geometry supports drill stability and more consistent hole quality.
Wear-resistant performance: Diamond coating helps reduce abrasive wear and supports longer, more predictable tool life.
