Frequently Asked Questions (FAQs)
1. What is a Forstner bit Particularly 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?
Cutting precise, large-diameter holes with a portable power drill or drill press can be done with a variety of drill bit attachments, including a hole saw, spade bit, or Forstner bit.
3. What is difference between hole saw and Forstner bit?
For Forstner bits, the hole will be flat bottomed, but also will punch through depending on the depth of the material. A hole saw will only cut holes through the material that is used. The real difference starts when you want to drill deep holes. With Forstner bit, you can use an extension to cut deeper.
4. Are Forstner bits better than spade bits?
Simply put, spade bits are fast and dirty, while Forstner bits are slow and precise. In fact, if you're not careful when using a spade bit, the speed can cause tear out and splintering on the opposite side of the workpiece.
