Worked very well. Had to add T&G to some repair boards for oak flooring. Matching the existing T&G that was already there was easy.

What is the max router speed for a bit this diameter?
JOHN G on Jul 21, 2017
Can you buy separate (spare) cutting disk, shims and bearings?
Ted B on Dec 19, 2015
BEST ANSWER: While I never have purchased separate parts I have used existing shims & bearings from other bits. Now that being said you can also go to a specially wood store like "Woodcraft" and purchase additional cutting disks. The router section of the store has large selection of various bits and parts. Only question is will the cutting disk fit the Rockler shank?
Will the diameter of the bit fit the baseplate on the Rockler convertible router table (for compact router)?
Mike on Feb 23, 2020
BEST ANSWER: If I correctly understand your question you will need to order a large opening insert. I belive you can solve the issue with products found on page 24 of the February 2020 catalog. Thank you for your question. Michael M
