3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 6X3/8X1-1/4, 10 MIC, 1 ea/Case

3M has developed an innovative bonding technology incorporated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant advancement in precision tool finishing. This proprietary "Trizact bond" delivers exceptional surface finish results while preventing profile distortion and maintaining cutting edge integrity throughout the polishing process. The wheel was engineered specifically for polishing the flutes of drills and endmills, and it uniquely combines the advantageous characteristics of both resin-bond diamond wheels and non-woven abrasive wheels into a single, highly effective tool. This hybrid approach enables efficient polishing operations while preserving sufficient structural rigidity to allow for precise truing and dressing procedures and consistent adherence to complex tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features diamond particles that are uniformly distributed throughout the entire wheel structure. As the wheel undergoes normal wear during operation, new, sharp diamond particles are progressively exposed to the workpiece surface, ensuring that a keen cutting edge is perpetually maintained. This continuous exposure of fresh abrasive material results in reliable, predictable performance characteristics that enhance overall productivity, reduce the occurrence of rejected parts requiring rework, and elevate the quality standards of finished components.

While the 685DC can be utilized with portable grinding tools, it was specifically engineered for integration with CNC grinding machines and automated manufacturing environments. This design philosophy enables seamless incorporation into existing production workflows without requiring significant process modifications.

Polishing round cutting tools to achieve a mirror-quality finish can substantially extend tool longevity and enhance overall part quality. Superior surface finishes enable tools to operate at lower temperatures and maintain sharper edges during extended use. When the flute surfaces of drills and endmills are polished to a finer degree, chips generated or abraded from the workpiece surface can be evacuated more readily with reduced friction and minimal heat generation. This improved chip evacuation not only contributes to superior surface quality on machined components but also extends the functional life of the cutting tools themselves.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which comprises a carefully selected assortment of equipment and consumable products optimized for rapid, consistent, and fully automated tool grinding and polishing operations. Each individual component within this integrated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives products, can be deployed independently or combined with other system components to establish a fully integrated grinding and polishing solution that adapts readily to most contemporary production environments. Furthermore, 3M provides an extensive selection of wheel profiles and configurations specifically designed for round tool grinding applications. The company's comprehensive Superabrasive Wheel lineup encompasses multiple construction types suited for both general-purpose grinding operations and specialized CNC machine applications, offered with either cubic boron nitride (CBN) or diamond abrasive materials.
