Sanding tool replacement grinding head tips are essential consumable accessories for rotary tools, die grinders, and mini drills. These abrasive bits are designed to fit onto power tools for a variety of surface finishing tasks, including grinding, polishing, deburring, rust removal, and edge shaping on materials such as metal, wood, plastic, stone, and glass .

Unlike standard sanding discs or sheets, these specialized tips feature a small diameter shank (usually 3mm or 1/8 inch) and come in a variety of shapes like cylindrical, conical, ball, and flap wheel configurations. They are ideal for reaching tight corners, detailed engraving work, and precision surface preparation in electronics repair, jewelry making, mold processing, and general DIY projects.

Key Features

• Multiple Tip Shapes & Sizes: Available in cylindrical, conical, spherical (ball), and flap wheel shapes to suit different contours and hard-to-reach areas. Standard sizes include head diameters of 10mm, 15mm, 9.5mm, and 30mm for versatile use .
• Universal Shank Diameter: Most tips feature a standard 3mm (approx. 1/8 inch) shank, making them compatible with the vast majority of rotary tools, mini drills, electric grinders, and pneumatic engraving pens .
• High-Hardness Abrasive Materials: Constructed from durable abrasives such as Aluminum Oxide (Corundum), Zirconia Alumina, and industrial-grade Emery (Silicon Carbide) to ensure sharpness, wear resistance, and efficient material removal .
• Efficient & Low-Dust Operation: Engineered for fast polishing speeds with minimal dust and noise, these heads provide a smooth finish on irregular and contoured surfaces .
• Wide Application Range: Suitable for grinding welds, deburring cut metal, removing rust, shaping wood, polishing plastics, and engraving stone or ceramics .
• Quick-Change Design: Designed for easy installation; simply insert the shank into the collet of your rotary tool and tighten, allowing for rapid swapping between different grits and shapes.
