[555477]
Achieve flawless, swirl-free finishes on difficult woods and composite materials. The ShopSmith 12" Conical Sanding Disc utilizes a unique 4° tapered cone design that turns your MARK 7 into a high-precision edge-sander and jointing power tool—eliminating tear-out on figured grain and protecting costly jointer knives.
Key Capabilities & Applications
Tear-Out Free Grain Jointing: Smooth highly figured woods like birdseye, curl, and burl without the chipping or tear-out common with jointer blades.
Glue-Ready Composite Edges: Safely joint plywood, MDF, particleboard, and laminated materials that would quickly dull standard steel knives.
Glass-Smooth End Grain Shaving: Shave end-grain workpieces precisely to final length without leaving burn marks or rough edges.
Aggressive Single-Pass Stock Removal: Remove up to 1/8" of material in a single pass using coarse abrasives without bogging down.
Essential Knife Sharpening Component: Serves as the required drive abrasive for the ShopSmith Planer/Jointer Knife Sharpener [555471] to grind out nicks and restore razor-sharp edges in-shop.
Engineered Precision—How the 4° Conical Geometry Works
The 4° Tapered Steel Core: The disc face features a 4° cone taper starting 1-1/4" from center and extending to the outer rim.
Opposing Straight-Line Action: Tilting your MARK table to 4° brings a ~1/4" vertical band of the disc perpendicular to your workpiece face.
Swirl-Free Grain Parallel Alignment: As you push stock along the rip fence or miter gauge, the abrasive moves in a straight vertical line parallel to the workpiece edge—delivering a mirror-smooth finish completely free of circular orbital swirls.
