Double Margin Straight Flute Drills

When you need a drill custom-built for precision drilling tolerances and stability, consider adding the Double Margin Straight Flute Drill to your arsenal of cutting tools. Double Margin Straight Flute Drills include, as the name implies, a second margin behind the main margin. The second margin on this cutting tool burnishes the hole as the main margin creates it, creating a smooth finish and a far more accurately measured hole. In addition to the accuracy of the cut, this type of drilling often eliminates the need to reaming altogether.
