Prefinished Cabinet Edge Profiles
Add roundovers, chamfers, or beaded details to prefinished cabinet doors and shelves without scuffing the finish. The 1/2-in sleeved bearing rides the finished edge while the cutter forms the profile, preventing mar and burn on clear-coated or painted surfaces.
Template-Guided Inlay on Veneered Panels
Route shallow recesses for inlays on veneered plywood or MDF with a template. The non-marring sleeve protects delicate veneer edges as the piloted bit follows the template, ideal for compass roses, logos, or geometric inlays on tabletops.
Laminate Countertop Seam Cleanup
Flush-trim or ease edges on post-formed or flat-laminate countertops after install. The enlarged bearing protects the laminate face while you clean stray adhesive, align edges, and add a micro-chamfer for chip resistance.

Guitar Binding Channel Touch-Up
Safely true and refine binding channels on finished guitar bodies or tops. The 1/2-in OD sleeve keeps the bearing off sensitive lacquer while the bit trims high spots for a tight, clean binding fit.
