Yakamoz 6PCS Drill Tap Combination Bit Set HSS Deburr Countersink Bit 1/4 Hex Shank Tool Kit | Imperial

Q: What are the thread sizes this tool can do?

First off, this is NOT SAE. The bits are BSW (British Standard Whitworth). They are 1/8-40, 3/16-24, 5/32-32, 1/4-20, 5/16-18, 3/8-16.

Q: Are these equivalent to NC national course?

I know that the 1/4" thread one has NC stamped on it so I assume the others are too.

Q: Total length? drilling/taping portion length?

From tip - drill part is 1/8", from there, thread cutting part is 1/2", from there, counter-sink part is 1/2", as accurately as I can measure without a caliper. These dimensions are shared by all diameter bits.
