Q: I need to revise my earlier question: why does this set come with a 10-32 unf tap? shouldn't they all be unc taps?

The 10-32 tap is the most common #10 tap. 10-24 is usually found in Chinese hardware assortments and on certain farm equipment and threaded holes in soft aluminum products. Both are included in most tap sets.

Q: Are these split point drill bits?

Yes, with 135-degree split point.

Q: What size are the bits and taps

6 - 40 Tap, #33 Drill; 8 - 36 Tap, #29 Drill; 10 - 24 Tap, #25 Drill; 10 - 32 Tap, #21 Drill; 1/4'' - 28 Tap, #3 Drill; 5/16'' - 20 Tap, #F Drill; 3/8'' - 24 Tap, #Q Drill; 7/16 - 20 Tap, 25 - 64'' Drill
