will it work on a hitachi 4 1/2” grinder?

I don’t know about the Hitachi 4 1/2 , but it works on a Bosch 5 “ and a Makita 7” most likely it will work on the Hitachi. I had to purchase a universal nut with centering washer at Home Depot or Lowe’s

Is this disc compatible with a galaxia angle grinder?

Yes, it will work. It comes with a bushing to fit a five-eights arbor. Make sure the disc isn't touching the gaurd before turning on your tool. If it does touch, remove the gaurd. These tools can be dangerous, use a full face mask, clamp your wood firmly to a stable surface, and hold the grinder firmly with two hands. It's a great tool once you get used to it. I prefer these to the expensive arbortech planers.

Will this sharpen a carbide tip

NO, this tool is for wood sculpting, for carbide tips, see, on amazon,3 Inch Flat Shape Diamond Grinding Wheel 150 Grit 1/2" Bore for Grinder Cutter Grinding Metal Hard Alloy Glass Tiles Ceramics (78x12.7x10x10mm) $20.00 plus shipping

Are these compatible w/ a Dewalt die grinder?

The Shaping Wheels will fit most Dewalt '4-1/2" Angle Grinders', however the Kutzall 1/4" Shaft Burrs will fit most Dewalt Die Grinders.
