3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 5 in x 3/4 in x 1-1/4 in, 10 Micron, 1 ea/Case

3M has revolutionized the tool polishing industry by introducing an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This proprietary "Trizact bond" delivers exceptional surface finishing quality while preventing any distortion to the tool's profile or cutting edges, ensuring a consistently polished appearance throughout the grinding process. Engineered specifically for polishing the flutes and cutting surfaces of drill bits and end mills, this advanced wheel merges the superior cutting characteristics of resin-bonded diamond abrasives with the controlled flexibility of non-woven abrasive technology, enabling efficient material removal while maintaining sufficient structural integrity for automated truing and dressing operations and precise conformity to intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features strategically distributed diamond particles throughout its entire composition. As the wheel gradually wears during operation, a continuous supply of fresh, sharp diamond grains becomes exposed to the workpiece surface, maintaining optimal cutting performance. This self-replenishing cutting action ensures consistent and reliable results that translate into measurable improvements in production efficiency, reduced defect rates requiring rework, and enhanced overall part quality.

Although this polishing wheel can be utilized with handheld grinding equipment, it has been specifically engineered for integration with CNC grinding machinery, allowing for seamless incorporation into existing automated manufacturing workflows and processes.

Achieving a mirror-quality finish on cylindrical cutting tools through precision polishing can substantially extend tool lifespan and enhance machined part quality. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges throughout their service life. When the flute geometry of drills and end mills receives a refined polish, chips generated during the cutting process flow away more freely, reducing frictional resistance and minimizing heat generation. This improved chip evacuation not only produces better surface quality in the finished workpiece but also contributes significantly to extended tool longevity.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, a fully integrated collection of precision equipment and specialized abrasive products designed to deliver rapid, repeatable results in automated tool grinding and polishing operations. Every element within this integrated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, operates as both independent units and as interconnected components, enabling manufacturers to configure customized grinding and polishing solutions that align with their unique production requirements while adapting readily to established manufacturing infrastructure. Furthermore, 3M provides an extensive selection of wheel geometries and configurations specifically optimized for cylindrical tool grinding applications, with Superabrasive Wheels available in multiple construction options suitable for general-purpose grinding and CNC machine applications, offered with either CBN or diamond abrasive materials.
