Good quality
I've purchased Rockler bits in the past, and they seem to be of good quality. I used this to inlay a router plate into a router table I was building.

Rockler Pattern Router Bit
I used the router bit to rabbit sewing machine cabinet hinges flush in a melamine surface. The router bit was very sharp and cut the melamine without chipping and was easy to use. I did have to make a template for the router to follow.

Do I need a template or guide to mortise for a hinge?
Thomas C on Jul 24, 2015
BEST ANSWER: I have used a template (jig) and free hand. I prefer free hand. I draw the outline of the hinge on the wood. I use a chisel to score the outline. Then I use a small router to cut the mortise, erring on the side of being shy of my chisel lines. Then I clean up what's left (and corners) with a sharp small chisel.
Practice makes perfect. You will want to practice this 10 or 15 times before you use it.
Looking for a 1/4"dia x 3/8" H x 1/4" shank top bearing pattern bit, for fine detail mortising,is there such a thing ?
Bob B on Mar 30, 2016
BEST ANSWER: I bought a 3/8 cut length router bit like this several years ago the bearing wear out this year ordered a new one cut length was only a quarter missed the 3/8 got lengths
Is the bearing the exact size as the blade? I'd like the bit to cut the exact size as the template.
C W on Dec 3, 2016
BEST ANSWER: Yes. This bit trims flush with whatever you are registering to
