I have a 1 1/4" (31.75mm) diameter steel rod with a series of cuts along the length. Each cut is approximately 2mm deep (at its deepest point), and about 1.65mm wide; which I believe makes a 45 degree angle when viewed from the side. There's a slot every 2.5mm (centre to centre) along the bar.

I have an application where I'd like to reproduce this on a longer rod, and I'm wondering about the best way of doing it. I have a CNC machine - but it's really intended for wood/plastics/aluminium; though I have successfully cut 2mm sheet brass (albeit in several passes).
I was thinking I could mount the rod along the length of my CNC table, and use a 45 degree bit to make each cut across the rod - likely in several passes. Does that sound realistic - especially without coolant?
