3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 5X1/2X1-1/4, 10 MIC, 1 ea/Case

3M has developed an advanced bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant innovation in precision tool finishing. This specialized "Trizact bond" formulation delivers exceptional surface quality results while preventing profile distortion and preserving cutting edge integrity, all while maintaining a consistently polished surface finish. The wheel was engineered with particular emphasis on polishing the flutes of drills and endmills, leveraging a hybrid approach that merges the finest characteristics of resin-bonded diamond wheels with the versatility of non-woven abrasive technologies. This unique combination enables highly efficient polishing operations while preserving sufficient structural rigidity to accommodate automated truing and dressing procedures, as well as the ability to conform precisely to intricate tool geometries.

The 685DC wheel incorporates diamond particles that are uniformly distributed throughout the entire wheel structure. As the wheel gradually wears during use, a continuous supply of fresh, razor-sharp diamond particles becomes exposed to the workpiece surface, ensuring that the cutting action remains consistently sharp and effective. This self-renewing cutting action produces highly consistent and predictable polishing results, which directly translates into improved productivity metrics, a measurable reduction in rejected parts and rework requirements, and demonstrably higher quality standards for finished components.

While the 685DC wheel maintains compatibility with portable grinding tools, it was purposefully engineered for integration with CNC grinding machinery. This design philosophy allows for seamless incorporation into existing manufacturing workflows and automated production environments, maximizing efficiency and consistency across operations.

Achieving a mirror-quality finish on round cutting tools through precision polishing can substantially extend tool longevity and enhance overall part quality. Superior surface finishes contribute to more effective heat dissipation during cutting operations, allowing tools to maintain cooler operating temperatures and retain their sharpness for extended periods. When the flute surfaces of drills and endmills achieve exceptionally fine finishes, chips generated from workpiece material flow significantly more smoothly with considerably reduced frictional resistance and minimal heat generation. This improved chip evacuation capability not only protects the tool itself but also produces superior surface finishes on machined components while promoting extended tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a key component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a carefully curated collection of integrated equipment and consumable products. This complete system is optimized to facilitate rapid, predictable, and fully automated tool grinding and polishing operations. Each individual component within this automated system ecosystem—including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives—operates effectively as a standalone unit while also seamlessly integrating with other system components to create a unified grinding and polishing solution. This modular approach enables straightforward customization and adaptation to accommodate most existing manufacturing operations and production environments.

In addition to the 685DC wheel, 3M provides an extensive portfolio of wheel shapes and specialized configurations specifically developed for round tool grinding applications. The 3M Superabrasive Wheel lineup encompasses multiple construction variations designed for both general-purpose grinding requirements and specialized CNC machine applications, with options available in both CBN (cubic boron nitride) and diamond abrasive formulations to meet diverse finishing needs.
