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.

Feed rates can and should be adjusted depending on stack makeup, with higher feed rates in the composite portion and lower feeds in the metal portion. 2. Peck drilling may be necessary for enhanced quality and proper chip evacuation. 3. There are many factors that can effect successful stack drilling; please contact OSG about your specific application for best recommendation. 310 Drilling Technical WWW.OSGTOOL.COM
