3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 4X3/4X37/47, 10 MIC, 1 ea/Case

3M has revolutionized the tool polishing industry through the introduction of innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" formulation delivers exceptional surface finishing results while preventing any distortion to the tool's profile or cutting edges, ensuring that a consistently polished finish is maintained throughout the polishing process. Engineered specifically for polishing the flute surfaces of drills and endmills, this sophisticated wheel combines the best characteristics of resin-bond diamond abrasives with non-woven abrasive wheel technology, creating a hybrid solution that enables highly efficient polishing operations while retaining sufficient structural integrity to be properly trued and dressed, and to accurately follow even the most intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC is engineered with diamond particles that are uniformly dispersed throughout the entire wheel structure. As the wheel gradually wears during use, a continuous supply of fresh, sharp diamond abrasive particles is progressively exposed to the workpiece surface, maintaining optimal cutting performance and sharpness throughout the wheel's operational life. This design principle results in highly consistent and predictable polishing outcomes that directly contribute to increased productivity, substantially reduced reject rates and rework requirements, and markedly improved overall part quality.

While the 685DC wheel can be utilized with handheld portable tools, it was specifically engineered for integration with CNC grinding machines, where it functions seamlessly within existing automated manufacturing processes and workflows.

Polishing circular cutting tools to achieve a mirror-quality finish can substantially extend tool longevity and enhance the quality of the finished workpiece. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges throughout their service life. When the flute surfaces of drills and endmills are polished to a finer finish, chips generated during the cutting or abrading process can be evacuated more efficiently with significantly reduced friction and heat generation. This improved chip evacuation mechanism not only contributes to superior surface finishes on machined parts but also directly extends the operational lifespan of the cutting tool itself.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC is an integral component of the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a thoughtfully curated collection of equipment and consumable products that have been meticulously optimized to facilitate rapid, repeatable, and fully automated tool grinding and polishing operations. Each individual component within this advanced automated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasives, can function independently or be combined with other components to establish a completely integrated grinding and polishing system that can be readily adapted to complement most existing production facilities. Moreover, 3M provides an extensive portfolio of wheel profiles and specialized configurations that have been specifically developed for round tool grinding applications. 3M Superabrasive Wheels are manufactured in numerous construction types suited for both general-purpose grinding operations and specialized CNC machine applications, and are available with either CBN or diamond abrasive materials to meet diverse operational requirements.
