Drills for Composite Materials
The main issue with drilling holes in composite materials is de-lamination of the materials local to the hole when poor breakthrough of the laminate occurs.
The best drills for composite materials are either solid carbide or diamond grit depending on the materials in the laminate. Although more expensive, solid carbide can be sharpened and diamond can be re-coated, the effectiveness of these drill bits is best when matched to high speed drills. High speed drills allow the drill bit to do the work and reduce the amount of pressure exerted on the material reducing the risk of poor breakthrough and de-lamination.
The extracted drill tools are very effective at dust capture at source to make for a clean working environment.
