Where can I find these? Countersink, chamfer or Deburr tips.

Looking to see if anyone has a source or way to figure out where I can get more of these threaded chamfer or countersink bits for this tool. Bought at a swap meet and has no brand markings at all. I love the tool but the bits are dull and I need to replace them. Thanks in advance.

McMaster-Carr has them without the guide. 1/4-28 thread.

Google 'threaded piloted countersinks'...

You'll find bookoodles of them.
