When I buy a set of tools I want everything I need in that set to do the job. Most tap and die sets that I investigated only come with the necessary wrenches and perhaps an adapter or two. The only quality set I found that includes the drill bits necessary for tapping holes is the IRWIN Tools Deluxe 116 Pc. Tap and Die Set.
That is a huge bonus considering a full set of quality drill bits could cost $200 plus.
Not only does this set include all the necessary drill bits, it comes with a full array of support tools such as tap handles, stocks, adapters, thread gauges, and more.
The IRWIN Tools Deluxe 116 Pc. Tap and Die Set includes both: SAE and Metric Series: (6) Machine Screw sizes, (10) Fractional sizes, 16 Metric sizes, plus a 1/8″-27 NPT and 1/8″-28 BSP tap and die.
The IRWIN Tools Deluxe 116 Pc. Tap and Die Set is the most complete SAE and Metric set available.
All of the threading tools in this set are made from tempered high carbon steel and is ideal for the tradesman or home workshop.
