      Many customers are using the die drill configuration as a very effective reamer or core drill for producing close diameter smooth holes.
      Many years ago we discovered the sizing characteristics of the straight fluted die drill. However because the straight flute cannot "lift chips" out of the hole to the depth that can be drilled from solid it is limited to several diameters at most in vertical applications. That's why we developed the Koolcarb coolant feeding style drills. But in reaming or core drilling the die drill can be used to many more diameters deep than when drilling from solid.
