McMaster 2549A78 12-Piece Tap and Die Kit High-Speed Steel Tap and Carbon Steel Hex Die Kit

Use a single kit for many sizes of internal and external threads. The taps and dies are for use on most metal and plastic. High-Speed Steel—High-speed steel taps and dies last longer than carbon steel when used on similar material. Taper Chamfer—Taper-chamfer taps have 7-10 chamfered threads at the tip for cutting into the workpiece. They require less torque than other chamfer types, making them a good choice for starting threads and tapping through holes. However, a longer taper means that they cannot thread as close to the bottom of closed-end holes. Hex—Hex-shaped dies are for thread repair and can be used with conventional wrenches.
