Review on Klein Tools 53936 Wood Boring Bit by Keith Gonzales

Works great but takes some time. Most of my work is related to old wood. I can't "unscrew" the bit as it just unscrews. No problem in the new wooden frame. After 4 days of use it is ready for the first sharpening. Average compared to Irwin Tri-Flute or Bosch DareDevil bits. I'll see how it goes.
