3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 5 in x 1/8 in x 1-1/4 in, 10 Micron, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" formulation delivers exceptional surface finishing characteristics while preventing profile distortion and preserving cutting edge integrity throughout the polishing process. Engineered with particular emphasis on polishing the flute surfaces of drills and endmills, this wheel uniquely combines the superior cutting properties of resin-bonded diamond abrasives with the controlled flexibility of non-woven abrasive technology. This hybrid approach enables highly efficient polishing operations while retaining sufficient structural rigidity to accommodate automated truing and dressing procedures, ensuring the wheel consistently conforms to intricate tool geometries without compromise.

The 685DC wheel features a generous distribution of diamond particles uniformly dispersed throughout its entire structure. As the wheel undergoes normal wear during operation, previously embedded diamond particles continuously break away, exposing new sharp crystalline surfaces to the workpiece. This self-renewing cutting action produces highly consistent and predictable polishing results, which directly translates to enhanced manufacturing productivity, substantially reduced part rejection and rework rates, and demonstrably improved final part quality.

While the wheel can be utilized with handheld portable grinding equipment, it has been optimized specifically for integration with CNC grinding machinery. This specialized design allows for seamless incorporation into existing automated manufacturing workflows without requiring significant equipment modifications or process interruptions.

Achieving mirror-quality polished surfaces on cylindrical cutting tools can substantially extend tool operational life and enhance part quality. Superior surface finishes enable cutting tools to maintain lower operating temperatures and retain their sharpness for extended periods. When the flute surfaces of drills and endmills are polished to exceptional smoothness, the chips generated during cutting operations flow through the flutes with significantly reduced friction and minimal heat generation. This improved chip evacuation mechanism contributes substantially to superior surface finish quality in the final machined components while simultaneously prolonging the functional lifespan of the cutting tool itself.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as an integral component within 3M's comprehensive Cutting Tool Grinding and Polishing System, a fully integrated collection of precision equipment and specialized consumables engineered to deliver rapid, consistent, and reliably automated tool grinding and polishing capabilities. All system components, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasive products, can be deployed independently or combined synergistically to establish a complete, fully integrated grinding and polishing platform that readily adapts to nearly all existing industrial production environments.

3M maintains an extensive inventory of wheel designs and configurations specifically engineered for cylindrical tool grinding applications. 3M Superabrasive Wheels are manufactured in numerous construction variants suited for both general-purpose grinding operations and specialized CNC machine applications, offered with either cubic boron nitride (CBN) or diamond abrasive options to match specific operational requirements.
