3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 7/16 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 precision tool finishing. The proprietary "Trizact bond" formulation delivers exceptional surface quality while preventing distortion of tool profiles and cutting edges, preserving the integrity of the polished surface throughout the finishing process. This wheel is engineered specifically for polishing the fluted surfaces of drills and endmills, seamlessly combining the superior cutting characteristics of resin-bonded diamond wheels with the controlled abrasive action of non-woven abrasive technology. This hybrid approach enables highly efficient polishing operations while retaining sufficient structural rigidity to allow for proper truing and dressing procedures, ensuring the wheel maintains precise conformity with even the most intricate tool geometries.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC features diamond particles uniformly distributed throughout its entire structure. As the wheel gradually wears during operation, the matrix continuously exposes fresh, sharp diamond crystals to the workpiece surface, maintaining optimal cutting performance. This self-renewing cutting action produces remarkably consistent and predictable results, which translates into enhanced productivity, reduced scrap and rework expenses, and measurably improved component quality across production runs.

Although capable of operation on portable grinding equipment, the 685DC wheel has been optimized for use on CNC grinding machines, where it integrates efficiently into established manufacturing workflows and automated production systems.

When round cutting tools are polished to a mirror-like finish, the resulting improvement in surface quality can substantially extend tool life and performance reliability. Superior surface finishes help tools operate at lower temperatures while maintaining sharper cutting edges during use. A highly refined finish within the flute passages of drills and endmills facilitates smoother chip evacuation, reducing friction and minimizing heat generation. This enhanced chip flow mechanism not only improves the surface finish quality of machined workpieces but also contributes meaningfully to extended tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a key component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, a fully coordinated lineup of specialized equipment and consumable products engineered to deliver rapid, consistent, and fully automated tool grinding and polishing capabilities. Each component within this integrated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives product line, may be deployed independently or combined with other system elements to establish a complete, cohesive grinding and polishing solution that readily adapts to most conventional production environments. Furthermore, 3M provides an extensive selection of wheel profiles and structural configurations specifically developed for round tool grinding operations. The 3M Superabrasive Wheels portfolio encompasses numerous construction variations for both general-purpose applications and precision CNC machine grinding, available with either cubic boron nitride (CBN) or diamond abrasive media to suit specific application requirements.
