3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 6X1/4X1-1/4, 10 MIC, 1 ea/Case

At 3M, innovative bonding technology has been integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC to deliver exceptional results in tool finishing operations. The proprietary "Trizact bond" formulation produces outstanding surface finishes while preventing profile distortion and maintaining the integrity of cutting edges. By strategically combining the benefits of resin-bond diamond wheels with the versatility of non-woven abrasive technology, this wheel offers a unique solution specifically engineered to polish the flutes of drills and endmills with remarkable precision and efficiency. The hybrid design provides sufficient structural rigidity to enable reliable truing and dressing operations while faithfully conforming to even the most intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features diamond particles that are uniformly distributed throughout the entire wheel structure. As the wheel progressively wears through continued use, new, sharp diamond surfaces are continuously revealed to engage the workpiece, ensuring that the polishing edge remains consistently acute and effective. This self-renewing cutting mechanism delivers reliable and predictable polishing performance that translates directly into enhanced productivity, reduced scrap and rework expenses, and superior part quality.

Although the 685DC can be utilized with handheld equipment, it was specifically engineered to function optimally on CNC grinding machines. This design philosophy enables seamless integration into established manufacturing workflows, allowing operators to incorporate advanced polishing capabilities without requiring significant process modifications.

Polishing round cutting tools to achieve a mirror-quality finish offers substantial benefits in tool performance and longevity. Superior surface finishes enable tools to maintain lower operating temperatures and retain sharper cutting edges throughout their service life. When the flute surfaces of drills and endmills are refined to a higher finish standard, chips generated during machining are expelled more freely, resulting in reduced friction, decreased heat generation, and improved chip evacuation. These advantages culminate in better surface quality on machined components and significantly extended tool operational life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC operates as a cornerstone component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This integrated collection of precision equipment and specialized consumables has been meticulously optimized to enable rapid, consistent, and fully automated tool grinding and polishing operations. The system's modular architecture allows individual components—including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive wheels—to function either independently or in concert with one another, facilitating the creation of customized integrated systems that adapt effortlessly to most existing production environments. Additionally, 3M provides an extensive portfolio of wheel profiles and configurations specifically developed for round tool grinding applications. The complete 3M Superabrasive Wheel lineup encompasses multiple construction options suitable for general-purpose grinding and CNC machine applications, with selections available in both CBN and diamond abrasive materials.
