Cutting a grove in acrylic

Good morning
I am assisting a friend with an acrylic project. She has a 6D-6mm-4.2 engraving bit and I cant find the specifications of the bit anywhere to put into my CNC library. If anyone has these specs I would appreciate it.
Thank You
Eric

I googled that & got no exact matches. And enough of an assortment to be unsure of what bit you have. Got a link?

Typical engraving bits are just Vee-bits or engraving bits in CC. The only thing it looks at is the diameter & angle. The only reason to create a new tool is if the angle is different, or you want to remember the feeds & speeds for later use.

If this is the cutter she has I wouldn’t classify it as an engraving bit. Have you seen the cutter? It’s purpose is to cut a slot for LED
