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

3M has developed an advanced bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that delivers exceptional finishing capabilities. The proprietary Trizact bond formulation achieves outstanding surface quality results while preventing any distortion to the tool's profile or cutting edges, ensuring a consistently polished and refined finish. This wheel was engineered with the specific purpose of polishing the flute surfaces of drills and endmills, leveraging a sophisticated combination of resin-bond diamond technology and non-woven abrasive wheel characteristics. This hybrid approach enables efficient, controlled polishing operations while maintaining the structural integrity necessary for automated truing, dressing processes, and precise tracking along intricate tool geometries.

The 685DC features a uniform distribution of diamond particles throughout its entire structure. As the wheel makes contact with the workpiece during operation, the wear process continuously reveals fresh, sharp diamond particles, maintaining optimal cutting efficiency. This self-renewing cutting action results in reliable, repeatable performance that enhances manufacturing productivity, reduces defect rates and secondary operations, and elevates the overall quality of finished components.

Although this wheel can function with portable grinding equipment, the 685DC was specifically engineered for CNC grinding machine environments and integrates efficiently into established production workflows without requiring significant process modifications.

Achieving a mirror-quality polish on cylindrical cutting tools substantially extends tool longevity and enhances performance quality. Refined surface finishes enable tools to dissipate heat more effectively and retain sharpness longer during machining operations. When flute surfaces achieve superior smoothness, machined chips move through with minimal friction and reduced thermal generation. This improved chip evacuation contributes to superior surface quality in the finished workpiece and measurably extends cutting tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC operates as a component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which comprises a strategically matched selection of specialized equipment and consumable products designed to optimize rapid, consistent, and fully automated tool grinding and polishing operations. Each system element, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, functions independently or in coordinated combination to establish a fully integrated grinding and polishing solution that adapts readily to most current manufacturing environments. Furthermore, 3M provides an extensive portfolio of wheel designs and structural configurations specifically engineered for round tool grinding applications. The company's Superabrasive Wheel collection encompasses multiple construction variations suitable for general-purpose grinding operations and specialized CNC machine applications, offered with either CBN or diamond abrasive compositions.
