I would give 0 stars if this option was available. I used a drill to drill a 1/4" diameter hole in mild steel. The drill was sharp and drilled a hole. However, the tap immediately began to fill with removed metal and the cutting edges of the tap quickly snapped or wore off. I don't know if the drill will go further than a hole but I doubt it. The tool is made in China and is worse than a waste of time and money. I recommend everyone not to buy anything from Performance Tool!
