First, I'm assuming you want to put a keyway into a 3/8" hole for a shaft. Yes, this is very possible. Second, I would suggest getting a keyway broach set as opposed to individual broaches. Yes, it is more expensive, but over the years, it has certainly paid itself off for both teams I work with. If you want to go with the individual part numbers, then those are correct. Just make sure you select the 3/8" diameter for the latter part number.
