The FHC Wire Gauge general purpose drill bits are designed for fast drilling into Metal, Plastic, and Wood Materials. In General, it is a good idea to run at the slowest recommended speed when drilling into metal surfaces. Hard metals like steel as well as larger size drill bits require even slower speeds. With small bits (1/16" to 3/16"), you can drill through most metals at 3,000 rpm.
