1/4" Roundover (838.254.11)
Same geometry as H02, down to the radius and bearing, but a properly indexed CMT number this time. A second copy of the same quarter-round profile rather than a new shape in the drawer.

Notes
Functionally identical to H02. Same radius, same 1” OD, same bearing size and position, same shank. The only real difference is that this part number resolves cleanly against CMT’s published catalog, where H02’s .19 suffix doesn’t. Worth keeping both cataloged separately since they’re two physical bits, not one — a second one in the drawer means a spare when the first one’s edge finally goes.
Bearing rides below the cut, same as H02: the arc rounds the top corner, the bearing follows the vertical face underneath it.
