What materials can HSS twist drill bits be used on?
HSS twist drill bits are commonly used to drill into a wide range of materials, including metals, wood, plastics, and some composite materials. These bits are particularly well-suited for drilling into softer metals such as aluminum and mild steel, but they can also handle drilling into harder materials, like stainless steel, with the proper technique. When working with wood or plastic, HSS drill bits provide clean, accurate holes. However, for very hard materials like cast iron or certain alloys, it may be necessary to choose a different drill bit design or material.
