Roundover router bit for edge profiling
The CMT 838.285.11 is a roundover router bit designed to produce smooth, rounded edges on workpieces. It suits woodworkers shaping picture frames, table edges or counter tops. The cutter creates a clean radius profile in a single pass.
1/4 in shank fits standard collets
The bit uses a 1/4 in shank that matches common router collets. The overall diameter is 1 1/8 in with a 1/2 in cutting length and a 1/2 in bearing diameter. These dimensions determine the profile size and bearing guidance.
Bearing-guided for straightforward setup
The integrated bearing rides against the workpiece or a template, so no fence is required. Ensure the shank is fully seated and the collet tightened before starting. Check bearing rotation and cutter sharpness periodically to avoid burn marks.

Questions about this item
How does the 1/2 in cut length affect the depth of the roundover profile?
The 1/2 in cutting length allows the bit to produce a roundover profile up to that depth in a single pass, suitable for standard edge rounding on boards of matching thickness.
What does the 1/4 in shank mean for router compatibility?
The 1/4 in shank fits any router collet sized for 1/4 in shanks, which is the common size on many compact and mid-size routers.
Will the 1 1/8 in overall diameter clear my router base opening?
The 1 1/8 in overall diameter requires a base-plate opening at least that wide; check your router's base aperture before use.
