3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 8 in x 1/4 in x 1-1/4 in, 10 Micron, 1 ea/Case

3M has revolutionized the tool finishing industry through the introduction of advanced bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This innovative "Trizact bond" technology delivers exceptional surface finishing results while preventing any distortion to the tool's profile or cutting edges, ensuring a consistently polished appearance throughout the finishing process. Primarily engineered for polishing the flutes of drill bits and endmills, this specialized wheel merges the superior cutting capabilities of resin-bond diamond wheels with the controlled finishing characteristics of non-woven abrasive wheels, creating a unique hybrid that enables efficient polishing operations while maintaining sufficient structural integrity for precision truing and dressing procedures and precise adherence to even the most intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC incorporates diamond particles that are strategically dispersed uniformly throughout the entire wheel structure. As the grinding wheel experiences wear during operation, fresh, sharp diamond particles are progressively exposed to the workpiece surface, ensuring the cutting action remains consistently sharp and effective. This continuous exposure of new abrasive material results in highly predictable and consistent performance characteristics, which directly translates to improved productivity levels, a significant reduction in part rejections and costly rework procedures, and an overall enhancement in the quality and precision of finished components.

While the 685DC wheel can be adapted for use with handheld portable tools, it was specifically engineered and optimized for installation on CNC grinding machines, where it integrates effortlessly into existing automated manufacturing workflows and production processes.

Achieving a mirror-quality polish on precision round tools can substantially extend tool longevity and enhance the overall quality of machined components. Superior surface finishes help cutting tools maintain lower operational temperatures and retain their sharpness longer during use. When the flute surfaces of drill bits and endmills receive a finer finish, chips that are cut or abraded from the workpiece surface are able to evacuate more readily with minimal friction and reduced heat generation. This improved chip evacuation flow contributes to superior surface finishes on machined parts while simultaneously extending the operational lifespan of the cutting tool.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a fully coordinated collection of specialized equipment and consumable products engineered to facilitate rapid, consistent, and automated tool grinding and polishing operations. Each constituent element of this advanced automated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasives products, maintains the flexibility to be deployed independently or integrated together to establish a complete, unified grinding and polishing solution that can be readily adapted to accommodate most conventional production environments. Furthermore, 3M provides an extensive selection of wheel profiles and configurations specifically tailored for round tool grinding applications. 3M Superabrasive Wheels are manufactured in numerous structural variations suitable for both general-purpose grinding operations and specialized CNC machine applications, available with either conventional CBN (cubic boron nitride) or premium diamond abrasive materials.
