Besly Popular Special Combination Tap/Drills require only one setup for drilling and tapping in a single operation. The drill point is designed to reduce drilling time on high production jobs. These tools are suitable for multi-spindle applications and can drill and tap thru-holes in material with a thickness up to 1-1/2 times the diameter of the tap. The self-centering helical point helps eliminate the need for spot or center drilling and holds tight tolerances.
