Picture a bit fuzzy and the pop-up and ad a PITA. With that said it looks like a coolant feed through cutter for a CNC machine.

Maybe a special reamer, a profile cutter.

Looks to me as if it is a drill and countersink in one tool. Not been around CNC units but I did not think thay used screw in tooling.

This looks alot like the profiling tooling that a company I worked for many moons ago used. Only on a different scale. The company made aluminum manifolds for Navistars air conditioning systems. They would predrill the billit and then use a profiling cutter such as this to get the correct sized hole and inside dia. profile for valving and ports. Ours were made with a coolant port through the cutter. They were an expendable tool, as we would dispose of them frequently since they would wear and be out of spec. for the ISO standards.

These cutters are for drilling, reaming and countersinking in one operation. they are usually used in the aircraft industry with a depth stop cage to control the Countersink depth.
Cutter and Cage can be seen here:-

Hope this helps

Other than having the threaded end for changing cutter heads on the shank, it looks like a counterbore tool made for a specific part. Use them all the time on screw machines and CNC lathes. The ones I've used were all straight shank (3/4inch or 1 inch dia.) instead of having the small threaded end.

Some are purchased ready made (special order), and some are simply made 'in-house' in the tool room by modifying an end mill, drill, or reamer, depending on how big of steps are needed between the diameters.

Rough drill / bore the holes with each size drill leaving .010-.030 on depth(s) and diameter(s), and then run that special tool in to blend everything together to hold all the depths & diameters without having any runout between them.

With all the hole sizes drilled individually, any or all of the drills can wander off center. These tools true everything up and finish the part, plus put in radii, fillets, and chamfers.
