3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 4 in x 5/8 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 outcomes while preventing distortion of tool profiles and cutting edges, ensuring a consistently polished finish is maintained throughout the polishing process. This specialized wheel was engineered primarily for polishing the flutes and intricate geometries found in drills and endmills. The 3M™ Trizact™ Diamond Polishing Wheel 685DC uniquely merges the superior cutting characteristics of resin-bond diamond wheels with the versatile properties of non-woven abrasive wheels, creating a hybrid solution that enables efficient material removal while preserving adequate structural rigidity for precision truing and dressing operations that conform precisely to complex tool geometries.

The wheel features diamond particles strategically distributed uniformly throughout its entire structure. As the wheel gradually wears during use, the material design ensures that fresh, sharp diamond surfaces are continuously exposed to maintain optimal cutting performance against the workpiece. This engineered wear characteristic produces consistent, predictable results that directly enhance manufacturing productivity by reducing defective parts and minimizing the need for rework while simultaneously elevating the overall quality standards of finished components.

Although the 685DC wheel can be utilized with handheld equipment, it was specifically engineered for deployment on advanced CNC grinding machines where it integrates efficiently into established production workflows and manufacturing protocols.

Polishing round cutting tools to achieve a mirror-quality finish substantially enhances tool longevity and component quality. Superior surface finishes enable tools to maintain lower operating temperatures and retain sharp edges during extended use. When the flute areas of drills and endmills are polished to finer surface tolerances, chips generated during the cutting or abrading process flow more efficiently through the flutes with significantly reduced friction and heat generation. This improved chip evacuation contributes to superior surface finishes on machined workpieces and extends overall tool service life.

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 fully coordinated collection of specialized equipment and consumable materials developed and optimized to facilitate fast, reliable, and fully automated tool grinding and polishing operations. All components within this integrated system, including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives, can be deployed independently or configured together to establish a complete, cohesive grinding and polishing solution that seamlessly adapts to most conventional production environments. Furthermore, 3M provides an extensive selection of wheel profiles and specialized configurations specifically designed for round tool grinding applications. The 3M Superabrasive Wheels product line encompasses multiple construction variations suited for general-purpose grinding requirements and CNC machine applications, offered with either CBN or diamond abrasive materials.
