3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 4X9/16X1-1/4, 10 MIC, 1 ea/Case

3M has developed and integrated an innovative bonding technology 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 a consistently polished and refined finish. Engineered with the primary application of polishing the flute channels in drill bits and endmills, this wheel successfully marries the beneficial characteristics of both traditional resin-bond diamond wheels and modern non-woven abrasive wheel technology. The synergistic combination of these two wheel types enables highly efficient polishing operations while preserving sufficient structural integrity to allow for precision truing and dressing procedures, as well as the ability to faithfully reproduce intricate tool geometries during the polishing process.

The 685DC wheel features a dense distribution of diamond particles throughout its entire structure. During operational use, the wheel gradually wears away, continuously revealing fresh, sharp diamond particles that engage with the workpiece surface. This self-renewing cutting action results in remarkably consistent and dependable performance characteristics. The reliability of this performance translates directly into measurable manufacturing benefits, including enhanced productivity levels, substantially reduced scrap and rework costs, and overall improvements in the finished quality of machined components.

While the 685DC can function effectively as a portable tool attachment, it has been specifically engineered for integration with CNC grinding machinery. This design philosophy enables seamless incorporation into existing manufacturing workflows and production environments.

Achieving a mirror-quality polished finish on cylindrical cutting tools can substantially extend tool lifespan and enhance the quality of work produced. Superior surface finishes contribute to lower operating temperatures and help tools maintain their sharp cutting edges throughout use. When the flute channels of drills and endmills are polished to a fine finish, machining chips and debris can flow more readily through these passages with significantly reduced friction and heat generation. This improved chip evacuation not only contributes to superior surface finishes on machined workpieces but also extends the functional life of the cutting tools themselves.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a central component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System. This integrated collection of specialized equipment and complementary consumable products has been carefully optimized to facilitate rapid, reliable, and fully automated grinding and polishing operations for cutting tools. Each individual component within this automated system—including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives product line—can be deployed independently or configured in combination with other components to establish a complete, unified grinding and polishing solution. This modular approach provides exceptional flexibility and can be readily adapted to accommodate most existing production facilities and manufacturing processes.

Additionally, 3M provides an extensive selection of wheel profiles and structural configurations that are specifically optimized for cylindrical tool grinding applications. The company's Superabrasive Wheels line encompasses numerous material constructions suitable for both general-purpose grinding operations and specialized use on CNC machinery, with options featuring either cubic boron nitride (CBN) or diamond abrasive materials.
