Frequently Asked Questions (FAQs)
1. What is a Forstner bit good for?
A: Forstner bits are mostly used in the woodworking industry to drill holes that are larger than those that can be made with ordinary drill bits. While other drill bits, such as spade bits, can perform a similar function, Forstner bits are significantly more precise and produce a clean cut with a flat bottom.
2. Can I use a Forstner bit with a hand drill?
While each one has its advantages, the Forstner typically drills the cleanest holes. But Forstner bits can also be tricky to use in a portable (handheld) drill, as they're better suited for use in a drill press.
3. Are Forstner bits better than spade bits?
Make sure you don't increase the speed too much—a huge benefit of the Forstner bit is the precision, and you will need to work slowly to achieve that. Unlike the spade bit, the Forstner bit is ideal for creating a neat, precise cut. You can use them to create flat-bottomed holes and even overlapping holes!
4. Can you use Forstner bits in a router?
A router is too high speed to use with forstner bits! Use a drill press or hand held drill with great care.
