1. Coolant is not needed, however, make sure dust is efficiently collected. 2. Peck drilling is not needed if drilling depth is less than 3D. 3. The machinability of CFRP depends on physical makeup and percentage of contents, both speed & feed may need adjustments depending on material. 4. Feed rate can be and should be adjusted depending on surface layer makeup. 5. Feed rates can be increased when an approved coolant is utilized. 6. Please contact OSG for specific application questions.
