Worked great had to buy a 3/8" bit collet but now have all 3 and this set works great. I would give it 5 stars other than the need for a special 3/8" collet or collet adapter.
These bits are of very little use. I wouldn't go so far as to say they're rubbish, but they're not much better. They're very good at drilling holes straight down (which is why this rating is 2 stars and not 1 star), but if you use them to route a jig, even at the smallest depth, they dull SUPER quickly with each pass . I had burned out the plywood after two passes that were about 20 inches long and only removed 1/8 inch with a 1/2 inch bit. I would return them but I don't have a return windowβ¦
