Review on 🔍 Kodiak Cutting Tools KCT129644 Diameter: Efficiency and Precision in One by Robert Aiono

I can't say enough good things about this item. I bought this just in case I could use it to drill out a broken screw extractor with a parting tool. After some careful, slow cutting, it went through about half the broken hardened steel of the screw extractor and was as sharp as it was when bought. Will definitely be used for similar tasks in the future.
