Carves thru poplar like butter!
Was using a cheap bit to carve shallow grooves into poplar on the router table. Might as well have been pushing on a Mack truck! This Rockler bit made the whole job a breeze. Was pleasantly surprised. I’ve not used other quality bits for such a task to compare, but for my needs this fits the bill in spades.

Something Different
Never worked with Core Box Bits before but will look forward to trying different application with them in the future.
First time I tried something like this and the Box Bit did a nice job.

Never having bought a router bit, I knew exactly what I needed a bit to do on my project. Rockler made it SO easy to select the right one by providing an easy to understand chart. I simply selected the bit based on the specs provided. FABULOUS! Rockler makes it SO easy for the do-it-yourselfer! Thank-you!!

Your item 90924, what is the total length of this router bit?
Phillip L on Aug 11, 2017
BEST ANSWER: The one I have is actually listed on the shaft as 90913 It is total length 1 5/8 long 1/4 shaft Cutting end 3/8 wide 3/8 total deep I know sometimes items show up slightly different on the web but when I type in your number and mine it seems to come up with the same 1/4 shaft 1/4 box bit Hope this helps
