How to Drill or Mill Phenolic Sheets Without Cracking?

Drilling or milling phenolic sheets without cracking requires careful attention to technique and proper tool selection. To achieve clean, crack-free cuts, use sharp, high-speed steel or carbide-tipped tools specifically designed for composite materials. Maintain a slow, steady feed rate and moderate spindle speed to prevent heat buildup. Employ backing boards to support the material and reduce the risk of exit splintering. Cooling the cutting area with compressed air or lubricant can help dissipate heat and extend tool life. For intricate shapes, consider using a CNC router with optimized cutting parameters. By following these best practices, you can successfully drill and mill phenolic sheets while preserving their structural integrity and achieving high-quality results in your projects.
