3M™Trizact™ Diamond Polishing Wheel 685DC 1A8, 6 in x 3/16 in x 1-1/4 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. This proprietary "Trizact bond" technology delivers exceptional surface finish quality while preventing profile distortion and maintaining cutting edge integrity throughout the polishing process. Engineered specifically for polishing the flutes of drills and endmills, this wheel combines the advantageous properties of resin-bond diamond wheels with the benefits of non-woven abrasive technology, creating a unique hybrid tool that enables efficient polishing operations while retaining sufficient structural rigidity for automated truing, dressing, and precise conformance to intricate tool geometries.

The 685DC wheel features a uniform distribution of diamond particles throughout its entire structure, which continuously regenerates a sharp cutting surface as the wheel wears down during use. This self-sharpening characteristic ensures that fresh diamond particles are perpetually exposed to the workpiece, resulting in sustained cutting performance. The consistent and predictable nature of this performance directly translates to improved production efficiency, reduced rejection rates, minimized rework requirements, and enhanced overall part quality.

Although the 685DC can be utilized with handheld tools, its design has been optimized for integration with CNC grinding machines, enabling seamless incorporation into existing automated manufacturing workflows and production environments.

Achieving a mirror-like polish on cylindrical cutting tools can substantially extend tool longevity and enhance the quality of finished parts. Superior surface finishes enable tools to maintain lower operating temperatures and preserve sharpness during extended use. When the flute areas of drills and endmills are polished to a finer finish, chips removed from the workpiece can be evacuated with significantly reduced friction and heat generation. This improved chip evacuation leads to better surface characteristics in the machined workpiece and contributes to prolonged tool operational life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC is an integral component of the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which comprises an intelligently coordinated selection of equipment and abrasive consumables engineered to facilitate rapid, reliable, and fully automated tool grinding and polishing operations. Each element within this integrated system—including the 3M™ Truing and Dressing Machine and 3M™ Superabrasives—functions as a standalone solution while also offering exceptional compatibility for use in combination with other system components, enabling the creation of a fully coordinated grinding and polishing solution that readily adapts to most contemporary manufacturing facilities.

Furthermore, 3M provides an extensive portfolio of wheel designs and configurations specifically developed for round tool grinding applications. The 3M Superabrasive Wheels collection encompasses diverse structural compositions suitable for general-purpose grinding operations and CNC machine applications, offered with either cubic boron nitride (CBN) or diamond abrasive materials.
