Precise fit and durability 1.1/8' diameter round shank for stable mounting and smooth rotation. Diamond material delivers consistent cutting, grinding, and shaping performance on hard surfaces. Designed for rotary tools for straightforward installation and use. Why you need this set Works on hard, abrasive materials where standard bits wear quickly (glass, ceramic, stone, hardened alloys). Diamond abrasive stays effective longer than common abrasives, reducing the need for frequent replacements. The round shank provides reliable concentricity for accurate work and less vibration. Practical performance Effective for precision grinding, carving, deburring, and surface preparation. Suitable for tasks that require controlled material removal and a fine finish. Performs well at typical rotary tool speeds when used with appropriate safety and operating practices. Compact, organized storage Comes organized in a plastic storage box for easy store and carry. Individual compartments keep bits protected, easy to find, and safe during transport. Typical use scenarios 1. Precision glass engraving and edge finishing to remove burrs and create smooth, accurate contours. 2. Ceramic and tile shaping or trimming for fitting pieces during installation or . 3. Light stone or hardened metal touchup and deburring where hardness and durability are required. Key attributes at a glance Shank: 1.1/8' diameter round shank Intended use: Designed for Rotary Tools Material: Diamond Packaging: Plastic storage box for organized storage and portability Notes for users Use appropriate speed, coolant/water, and safety gear when working with hard materials to prolong bit life and maintain safety. Ensure your rotary tool accepts the specified shank size before use.
