This Forstner drill bit is a must-have for any industrial workshop.As a result of using this product, i found that it made boring holes into hard materials like wood, metal, and plastics easier than ever before. The bit's design provides precise and clean holes that perfectly fit hinges, so you don't have to worry about any misalignments in your projects. While it's a bit pricier than some other drill bits on the market you get what you pay for in terms of quality..
