3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 5 in x 1/2 in x 37/47 in, 10 Micron, 1 ea/Case

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that represents a significant advancement in tool finishing capabilities. The distinctive "Trizact bond" formulation delivers exceptional surface finish results while preventing profile distortion and cutting edge damage, all while preserving the polished surface quality throughout the tool's lifecycle. This wheel was engineered with the specific application of polishing flutes in drills and endmills in mind, effectively merging the superior polishing characteristics of resin-bond diamond wheels with the versatile properties of non-woven abrasive wheels. This hybrid approach enables efficient and controlled polishing operations while retaining sufficient structural integrity to allow for precision truing and dressing procedures, ensuring the wheel can reliably conform to intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC is manufactured with diamond particles uniformly distributed throughout its entire structure. As the wheel gradually wears during operation, the bonding matrix continuously exposes fresh, sharp diamond crystalline structures to the workpiece surface, maintaining cutting effectiveness and performance consistency. This self-renewing cutting surface translates into reliable and reproducible polishing results, which directly contributes to enhanced productivity levels, a measurable reduction in defective parts and rework requirements, and overall improvement in the finished quality of manufactured components.

Although the 685DC model is capable of operation with handheld portable tools, it was fundamentally engineered for integration with CNC grinding machines, allowing for seamless incorporation into established manufacturing workflows and automated production environments.

Achieving a mirror-quality polish on cylindrical cutting tools can substantially extend tool operational life and enhance the quality of work produced. Tools with superior surface finishes experience reduced operating temperatures and maintain their cutting edge sharpness more effectively during use. When the flute surfaces of drills and endmills are polished to exceptionally fine specifications, the chips generated during machining are able to evacuate more readily with substantially reduced frictional resistance and thermal generation. This improved chip evacuation pathway results in superior surface characteristics on the machined workpiece itself, while simultaneously contributing to extended tool longevity and consistent performance.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as an integral component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a thoughtfully assembled collection of specialized equipment and consumable products. This system is specifically optimized to facilitate rapid, reliable, and fully automated tool grinding and polishing operations. The modular architecture of this automated system permits each component—including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives—to function independently when needed, or to work collaboratively to form a completely integrated grinding and polishing solution that can be readily adapted to align with most established production processes. Furthermore, 3M provides an extensive portfolio of wheel designs and structural configurations specifically developed for round tool grinding operations. The 3M Superabrasive Wheels collection encompasses diverse structural variants suitable for both general-purpose grinding applications and specialized CNC machine operations, with availability in both CBN and diamond abrasive material options.
