The .53-diameter hole is for clearance. It doesn't need a flat bottom - you can go ahead and drill it, though please make sure the bottom edge of the .501/.502 section is free of burrs.

Yes, please add the .02 chamfer to both ends of the hole, as well as the hex end.

Thanks,
Andy//

Howdy Andy,

On this part, I would like to drill the .53 dia. It looks like it is for clearance, but does it need to have a flat bottom? Also, the hole from either side doesn’t show any chamfering. I was going to add the usual .02 chamfer to both ends of the hole and the hex end. Sound good?//]
