MACHINING Tips : How to Drill and Tap Advanced Plastics and Polymers - Mitsubishi Chemical Advanced Materials
Mitsubishi Chemical Advanced Materials offers machining tips on how to drill and tap advanced plastics and polymers. The insulating characteristics of plastics require consideration during drilling operations, especially when hole depths are greater than twice the diameter. High-speed steel twist drills are sufficient for small holes. A slow spiral drill or general-purpose drill bit is recommended for large diameter holes.
