Combination Drill & Tap
A Combination Drill & Tap creates holes and cuts threads in a single time and money saving operation. The helical flute design of both the drill and tap permits the holes to be drilled and threads cut at relatively high speeds. 118 degrees helical point is self-centering, eliminating center punching or center drilling and reducing required feed rates. To achieve optimal performance and extended tool life, suitable lubricating/cutting oils or appropriate coolant fluids are recommended for most drilling/tapping operations.
