Same as preceding picture, a HSS [high speed steel], 3 flute, spiral tap. I'm guessing 10 or 12mm. Providing my browser displays same rows and spacing as yours...There is a tool known as a "Drap" which combines the operations, but IMHO they aren't very suitable to common machinery, to run drill proper speed and feed, and then the tap. Also limited to capacity in thread depth or material thickness. Same company makes a "Dreamer" combining Drill+Reamer, with same restrictions on best use.
Web search indicates a different opinion; hex drive [ie cordless] at least as small as 6-32! I've been wrong before.
I do not like driving conventional taps in three jaw chucks. Every chuck I own runs like the day I bought them, in stationary or rotating spindles. With some close to 40 years old, they've achieved a good return on investment.
Every place I've worked where that was a common practice, never had chucks without scored jaws. Result of slipping taps, often vicinity of the drive square, and much harder than drill shanks. Then again, many operators haven't been instructed how to operate drill chucks.

A couple of pictures of tap detail.
Al Toolmaker said, it's a machine tap, spiral type. Usually they should be used with machine, they do the thread in one passage, as opposed to three stage traditional taps. The tap used is a M10 x 1,25mm,it's not new so it needs a good large grip to make enough force, normal short ratchet tool is not enough.
They are pretty fast and accurate in my opinion, above all in this case with many holes to tap
I've done the same and made a 12" faceplate for my 14" lathe with the intent of running it in a 3 or 4 jaw chuck but I made the drive 'spigot' at the back from 4" diameter x 3/4" stock. The larger diameter means it can be welded or dowelled and bolted(as I did) and it won't slip in the chuck on heavy or interrupted cuts as it will with the small diameter shaft. Otherwise, pretty much the same.
You guys have me thinking I want a fixture plate that I can transfer from lathe chuck [or face plate] to indexer or rotab - carrying a mounted part. L98fiero's idea of a large spud makes it practical on a 10hp lathe. Cap screws and doweled in place makes it pretty universal, even clamped to a mill table!
Got to dig my remnant pile.
