Frequently Asked Questions (FAQs)
1. Why would you use a Forstner bit?
Unlike the standard twist bit, Forstner bits are optimized for woodworking applications and cut exceptionally precise, clean-edged holes in wood. Because they're designed to produce a minimum amount of tear-out when exiting the material, Forstner bits are the best bit for drilling through holes.
2. 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.
3. 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.
