PRODUCT FAQ

What is the grit size of the 3M™Trizact™ Diamond Polishing Wheel 685DC 1A8?

The grit size is 10 micron, which makes it ideal for fine polishing and finishing applications on hard materials like stone, glass, and ceramics.
What are the dimensions of this polishing wheel?

This wheel measures 6 inches in diameter, has a 1/2 inch thickness, and features a 37/47 inch arbor hole to fit standard equipment.
How many wheels come in each case?

Each case contains 1 polishing wheel, so you're purchasing a single unit per order.
What makes Trizact™ technology different from traditional polishing wheels?

Trizact™ technology uses a structured abrasive pattern that delivers more consistent cutting action and better surface finishes compared to conventional random abrasive wheels, resulting in faster material removal with less heat.
What types of materials can this wheel polish?

The 685DC 1A8 is designed to polish hard materials including natural and engineered stone, glass, granite, marble, and other composite materials used in countertops and architectural applications.

Breakthrough Technology Automates Tool Polishing

3M has developed an innovative bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC that delivers exceptional surface finishing capabilities. This advanced "Trizact bond" formulation achieves outstanding finish quality while preventing distortion to the tool's profile and cutting edges, preserving the polished surface integrity throughout the process. Engineered specifically for polishing the flutes of drills and endmills, this polishing wheel merges the best characteristics of resin-bonded diamond wheels and non-woven abrasive wheels, creating a hybrid solution that enables efficient material removal while maintaining the structural rigidity necessary for truing, dressing, and accurately following intricate tool geometries.

Loaded With Diamond

The wheel features diamond particles strategically distributed uniformly throughout its entire structure. As the wheel undergoes wear during operation, fresh and sharp diamond crystals are continuously revealed to engage with the workpiece, ensuring sustained cutting efficiency. This design principle results in reliable and foreseeable performance characteristics that enhance overall productivity, reduce the occurrence of rejected parts and rework operations, and elevate the overall quality standards of finished components.

Designed for Automated Truing and Dressing

Although this polishing wheel can be utilized with handheld equipment, the 685DC model was purposefully engineered for implementation on CNC grinding machines, where it integrates smoothly into current manufacturing workflows and automated production systems.

More Perfect Finishes Function Better

Achieving mirror-quality polished surfaces on round cutting tools can substantially extend tool longevity and enhance part quality. Superior surface finishes enable tools to operate at reduced temperatures while maintaining edge sharpness throughout the cutting process. When the flute surfaces of drills and endmills are polished to fine specifications, chips generated from the workpiece can be evacuated with considerably less friction and heat generation. This improved chip evacuation promotes superior surface quality in machined parts and contributes to extended tool service life.

Recommended Applications

Oil and Gas: PCD cutters and drilling bits
Thermal spray wear surfaces
Cutting Tools: Indexable insert grinding
Round tools
Primary Materials: Roll grinding and superfinishing
