As mentioned above each drill press is unique. Some are designed for metal while others are more appropriate for wood. Specs such as power and speed will determine this. You may also consider using a keyed chuck for metal work, as this creates more stability to enable you to do more heavy duty work. The key allows you to tighten more than you’ll be able to with brute force, keeping the drill bit securely in place and minimizing vibrations. The latter will ensure more accurate work too.
