3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 6 in x 7/16 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 that represents a significant advancement in precision tool finishing. The proprietary Trizact bond formulation delivers exceptional surface quality results while preventing profile distortion and cutting edge degradation, ensuring a consistently polished finish throughout the tool's service life. This wheel was engineered specifically for polishing the flutes and cutting surfaces of drills and endmills by merging the superior cutting performance of resin-bond diamond abrasives with the operational benefits of non-woven abrasive wheel technology. This hybrid approach enables highly efficient material removal while providing sufficient structural integrity for truing and dressing operations, allowing the wheel to reliably conform to the intricate geometries found in modern cutting tools.

The 685DC wheel features diamond particles that are uniformly distributed throughout its entire structure. As the wheel undergoes wear during operation, the worn surface continuously exposes new, unblunted diamond crystals to the workpiece surface, maintaining cutting efficiency throughout the wheel's operational life. This self-renewing cutting action produces uniform and highly predictable results, which directly translates to enhanced productivity, reduced scrap rates and rework requirements, and measurably improved finished part quality.

Although the 685DC can function effectively with handheld portable tools, it was specifically engineered for integration with CNC grinding machines in production environments. This design orientation enables seamless incorporation into existing automated manufacturing workflows and systems.

Achieving a mirror-like finish on round cutting tools through advanced polishing techniques can substantially extend tool longevity and enhance the quality of workpieces produced. Superior surface finishes enable tools to maintain lower operating temperatures and retain sharpness longer during cutting operations. When drill and endmill flutes are polished to exceptional smoothness, chips generated during the cutting or abrading process flow away more efficiently with minimal frictional resistance and reduced thermal generation. This improved chip evacuation not only enhances the surface finish quality of machined parts but also contributes significantly to prolonged tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a critical component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a fully integrated collection of specialized equipment and consumable products. This system has been meticulously optimized to deliver rapid, consistent, and fully automated grinding and polishing of cutting tools. The individual components of this automated system, which include the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive products, can be deployed independently for specific applications or combined together to establish a complete, fully integrated grinding and polishing solution that can be readily configured to complement most existing production environments.

In addition to the 685DC wheel, 3M provides an extensive selection of wheel geometries and configurations specifically developed for round tool grinding operations. The 3M Superabrasive Wheels portfolio encompasses multiple construction types designed for general machining applications and CNC machine tool integration, with options featuring either CBN (cubic boron nitride) or diamond abrasive materials to suit diverse grinding requirements.
