Router Bit for Roundover Profiles
The CMT 838.992.11 is a carbide-tipped roundover cut profile router bit designed for woodworkers and cabinetmakers who need to create smooth, decorative edges on workpieces. It suits professional workshops and serious hobbyists shaping hardwood, softwood or composite materials with a handheld or table-mounted router.
Cutter Diameter Decides Fit
The single specification that determines whether this is the correct bit is the 2-1/2 in cutter diameter, which sets the maximum radius of the roundover profile you can produce. A smaller or larger diameter will not match the same profile geometry, so verify your drawing or template calls for this exact size before purchasing.
Standard Half-Inch Shank Installation
The bit fits any router collet accepting a 1/2 in shank, so installation is a matter of inserting the shank fully and tightening the collet securely. The most common issue is insufficient shank engagement or a worn collet, which causes vibration and a poor-quality cut; always confirm the collet grips cleanly and the bit runs true before starting the pass.

Questions about this item
What does the 2-1/2 inch cutter diameter mean when I run this bit in my router?
The 2-1/2 inch cutter diameter produces a wide roundover profile in a single pass, so the finished edge radius matches that full width without needing multiple cuts.
How does the 1/2 inch shank affect compatibility and run-out on my router?
The 1/2 inch shank fits standard 1/2 inch collets and provides greater rigidity than smaller shanks, reducing vibration and improving cut quality on large-diameter bits.
What physical clearance do I need for the 1 5/16 inch cutting length and 3 13/64 inch overall length?
Ensure your router base opening and workpiece thickness allow at least 1 5/16 inch of bit projection, and that the 3 13/64 inch overall length clears the collet and any dust-collection shroud.
