Trims 3/4 inch plywood nicely (watch your bit speed)
Works well at low speeds. With 1/2" size, there is a lot of torque and I found that Bosch palm router wants to jump at higher speed setting. Bit cuts nicely at lowest speed, so I'm happy with it. Bottom bearing is closest to chuck, so I use this for jobs having a cutting template on top of piece.

Precise and exact!
This half inch router bit made some perfectly fitting box joints on drawer corners. Not too tight, not loose, just right!

I like all the router bits that I have ordered from Rockler.
Never been disappointed.
I’ll continue buy more, replacing my worn out ones, or new pattern bits.

Because of the top bearing and because of the small bit size

I use 1/4" soft Maple for the bases of some wooden baskets I am cutting out on my fret saw. The bases are 6" round. I am gong to ay a template and use the router bit to cut out the bases so they are round and smooth. Should be easier and smoother that hand sawing them out using my band saw.

is the bearing adjustable to get a longer reach?
tim s on May 19, 2015
BEST ANSWER: I looked at the bit and no you cannot adjust the bearing for a longer reach. The only way would be to put the bit in the collet out further, but you've got to watch that so that the bit will stay tight when you use it.
is the bearing adjustable?
A shopper on May 19, 2015
BEST ANSWER: It would not make sense to change the size since it is intended to match the cutting surface below it. If you are asking if it could be moved up my answer is, I do not believe so but haven't tried it.
can this be used to plunge cut, follow a template to cut out a hole?
John N on Aug 8, 2017
BEST ANSWER: I won't use it for plunge cutting. The flutes don't go to the center of the bit
Can this be used on fiberglass?
Daniel L on Apr 4, 2017
BEST ANSWER: No, I would not attempt to cut fiberglass with it. The bit would probably cut it since it is carbide, but not cleanly. and could rip it up.
