PRODUCT FAQ

What is the grit size of the 3M™ Trizact™ Diamond Polishing Wheel 685DC, and what does that mean for my application?

The wheel features a 10 micron grit size, which is considered a fine polishing grade. This makes it ideal for achieving smooth, high-quality finishes on hard materials like stone, glass, and composites. The 10 micron specification means you'll get excellent surface refinement in your final polishing stages.
What are the dimensions of this wheel, and will it fit my equipment?

The wheel measures 8 inches in diameter, 3/4 inch in width, and has a 1-1/4 inch center hole. Before ordering, I'd recommend checking your polishing machine's specifications to ensure compatibility with these dimensions, particularly the arbor size that matches the 1-1/4 inch center hole.
How long can I expect this wheel to last in typical use?

The lifespan depends on your specific application, material type, and how aggressively you're polishing. The Trizact™ technology provides excellent durability and consistent performance, but I'd recommend monitoring wear patterns with your particular process. Our technical team can provide more detailed guidance based on your exact polishing requirements.

Breakthrough Technology Automates Tool Polishing

3M has revolutionized the tool polishing industry through the introduction of an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This advanced "Trizact bond" formulation delivers exceptional surface finishing results while preventing any distortion to the tool's profile or cutting edges, thereby preserving the integrity of the polished surface. Engineered specifically for polishing the flutes of drill bits and endmills, this wheel represents a sophisticated fusion of resin-bond diamond technology and non-woven abrasive wheel construction, enabling operators to achieve highly efficient polishing operations while maintaining sufficient structural rigidity for precise truing, dressing, and consistent adherence to intricate tool geometries.

Loaded With Diamond

The 685DC wheel features a carefully engineered diamond particle distribution throughout its entire structure. As the wheel progressively wears during operation, newly sharpened diamond particles continuously emerge to engage the workpiece, ensuring sustained cutting performance and sharpness. This innovative design mechanism yields consistently reliable and predictable outcomes that substantially enhance operational productivity, minimize part rejection rates and rework requirements, and elevate the overall quality standards of finished components.

Designed for Automated Truing and Dressing

While this versatile wheel can be utilized with portable grinding equipment, the 685DC was purposefully engineered for deployment on CNC grinding machines, where it integrates effortlessly into established manufacturing workflows and production environments.

More Perfect Finishes Function Better

Polishing cylindrical cutting tools to achieve a mirror-quality finish can substantially extend tool longevity and enhance part quality. Superior surface finishes enable tools to maintain cooler operating temperatures and preserve their sharpness throughout extended use. A refined finish quality, particularly within the flute passages of drills and endmills, facilitates superior chip evacuation with minimal frictional resistance and heat generation. This improved chip flow mechanism not only contributes to superior surface quality in the final machined components but also significantly prolongs cutting tool service life.
