A standard twist drill is fine for drilling holes of small diameters, so Forstner bits are not usually found below ¼-inch. Sometimes, the smallest bit in a set will be ½-inch. The largest is usually 2 to 2 ⅛-inch. Although larger Forstner bits are available, they’re usually sold individually as they’re bigger than most people need. Metric Forstner bit sets are also available. These can be very useful when fitting cabinet hinges, for example, as the hardware is often metric. Imperial bits can be close to the same size, but not close enough for a good fit. The majority of Forstner drill bits are made of High Speed Steel (HSS). HSS drill bits are typically titanium-made drill bits and have a titanium oxide coating. They’re durable, resistant to corrosion, and can drill through wood and steel.
