PRODUCT FAQ

What is the grit size of this polishing wheel and what does that mean for my work?

This wheel features 10 micron grit, which is considered a fine polishing abrasive. This micron size is ideal for achieving smooth, refined finishes on diamonds and other gemstones, removing minor scratches and preparing surfaces for final polishing stages.
What are the dimensions of the 685DC wheel and how do I know if it fits my equipment?

The wheel measures 5 inches in diameter, has a 5/16 inch thickness, and a 1-1/4 inch center bore. Before ordering, simply check your polishing machine's spindle size and make sure it accommodates a 1-1/4 inch bore and can safely operate a 5 inch wheel at the appropriate RPM.
How many wheels come in each case?

Each case contains 1 wheel, so you're getting a single 685DC unit per order. This is perfect if you need a replacement or want to keep a backup on hand for your diamond polishing operations.
Why should I choose 3M Trizact Diamond wheels over other polishing options?

3M Trizact Diamond wheels are engineered with consistent diamond coating and superior bonding, which means longer wheel life, better cut rates, and more uniform finishes on your diamonds. You'll get reliable, professional results backed by 3M's reputation for quality abrasive products.

Breakthrough Technology Automates Tool Polishing

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 specialized "Trizact bond" technology delivers exceptional surface quality results while preventing any unwanted profile alterations or cutting edge deformation, ensuring the polished finish maintains its integrity. The wheel is engineered with primary application toward polishing the flute channels of drill bits and endmill cutters. By combining the advantageous properties of resin-bonded diamond wheels with the characteristics of non-woven abrasive technology, the 3M™ Trizact™ Diamond Polishing Wheel 685DC achieves highly efficient polishing operations while retaining sufficient structural integrity to undergo truing and dressing procedures and to accurately conform to intricate tool geometries.

Diamond-Loaded Construction for Consistent Performance

This polishing wheel incorporates diamond particles that are uniformly distributed throughout its entire structure. As the wheel gradually wears during operation, previously embedded diamond particles continuously become exposed, presenting fresh, sharp cutting surfaces to the workpiece and maintaining optimal cutting efficiency. This engineered wear pattern produces reliable and highly predictable performance outcomes, which collectively contribute to improved productivity metrics, a measurable reduction in part rejections and rework requirements, and an overall elevation in the finished quality of machined components.

Designed for Automated Truing and Dressing

While this polishing wheel can function with handheld portable tools, the 685DC was purposefully engineered for implementation on CNC grinding machines, where it integrates smoothly into current manufacturing workflows without requiring significant operational modifications.

Benefits of Superior Surface Finishing

Achieving a mirror-quality polished finish on cylindrical cutting tools can substantially extend tool operational life and enhance output quality. Superior surface finishes help reduce operational temperatures and preserve edge sharpness during use. When the flute passages of drills and endmills receive fine polishing, machined chips can evacuate from the cutting zone more readily with considerably reduced friction and heat generation. This improved chip evacuation capability not only enhances the surface quality of the final machined part but also meaningfully extends the functional lifespan of the cutting tool.

Recommended Applications

Oil and Gas – PCD cutters and drilling bits
