The number 1 handle has a notch on both sides so it can accept up to a 1/2” tap, I wonder if that’s what I should do to the #3 handle?
I think I’ll run that into town and have a machinist nip that out with a millI would. Looks like you will not have to take off much.
Use an endmill - if you have them, as a drill will just wander off. Or use a burr in a die grinder.
I’m not really sure on what sort of speed to fire this up at?
Use cutting fluid?
How “grabby” is this gonna be? Should the piece be in a vise or is free handing it ok?

The guy at Sowa looked at me funny when I asked about using an end mill in a drill press...
Thanks! Now I need a project to use them onOh, nice tools by the way!
What is the Sowa branch?
Are those countersinks Guhring brand by chance? They typically have a shorter head like that. I was ready to try some but the places that carry them seem to be pickup orientated so I ended up trying some Ebay specials which I wasnt holding high hopes for but they are OK.
You can freehand them I suppose on super light deburring) or spin them in a cordless drill. For best results they like a rigid setup that minimizes drawing the cutter into the work, slow rpm & cutting fluid. If you get a weird looking serrated finish that starts to develop & feed on itself, then its probably some or all the aforementioned factors. I was just using them in 303 stainless the other day, chamferring 0.050" DOC & they did an excellent job.

That’s a good idea!Or you could just "touch" two of the opposing "ground sections" at the square drives to a sander/grinder so they clear...saves a trip to town. The ground section is immaterial to use of the tap.
