Tackle detailed grinding, shaping and deburring in tight spaces with abrasive mounted points. These compact rotary accessories help with contouring, surface prep and precision cleanup on materials like steel, aluminum, stainless steel and cast iron. Mounted points attach via standard shanks to rotary tools, such as die grinders and flexible shaft machines, offering controlled material removal where standard wheels can’t reach.

Types And Shapes of Abrasive Mounted Points
Choose a shape that matches your task for cleaner, faster results.
- Cone: Chamfering, beveling and enlarging holes; reach tight internal corners.
- Cylindrical: Flat surfaces, slots, bores and internal grinding.
- Ball: Creating radiuses and smooth contours.
- Tree: Complex profiles, fillets and tight access points.
- Specialty profiles: Purpose-built forms for unique applications.
How To Choose Abrasive Mounted Points
Match the point to your material, tool and finish requirements.
- Abrasive type: Aluminum oxide for ferrous metals (steel, cast iron, stainless); silicon carbide for non‑ferrous metals, composites, stone and ceramics; diamond for the hardest materials like carbide, hardened steel and glass.
- Grit selection: Coarse for rapid removal and weld cleanup; medium for blending and deburring; fine for smoothing and finish work.
- Shank and speed: Confirm shank size (commonly 1/8 in. for rotary tools, 1/4 in. for die grinders) and keep tool RPM at or below the point’s maximum rating.
- Size and shape: Pick head diameters and profiles that fit the feature without touching adjacent surfaces.
- Bond hardness: Harder bonds hold shape on edges and tough alloys. Softer bonds expose fresh abrasive to help reduce loading.
- Access and control: Consider extended-reach points or flexible shafts for confined areas.
Proper Grinding Techniques
Good technique improves finish quality and tool life.
- Start at lower speeds, then increase as needed to maintain a cool cut.
- Apply light, steady pressure and let the abrasive do the work.
- Keep the point moving to avoid heat buildup and gouging.
- Pause periodically to allow cooling during extended grinding.
Always wear eye and face protection, secure the workpiece and verify maximum RPM before use.
Applications For Abrasive Mounted Points
Mounted points are versatile solutions for weld cleanup, smoothing beads without affecting adjacent surfaces. They also support mold and die maintenance by reaching complex internal geometries, and they’re handy for restoration, custom fabrication and precision repairs in the home workshop. Use the right abrasive and grit to move from fast stock removal to refined finishing.
