3M™ Trizact™ Diamond Polishing Wheel 685DC, 1A8, 8 in x 3/8 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. This specialized "Trizact bond" delivers exceptional surface quality while preventing any distortion to the tool's profile or cutting edges, all while preserving a consistently polished finish throughout the grinding process. The wheel was engineered with primary applications in polishing the flute surfaces of drills and endmills, leveraging a hybrid approach that merges the best properties of resin-bonded diamond wheels with the flexibility of non-woven abrasive technologies. This unique combination enables operators to achieve highly efficient polishing results while retaining the structural integrity necessary for precise truing and dressing operations that accurately follow even the most intricate and complex tool geometries.

The 685DC wheel features a uniform distribution of diamond particles throughout its entire structure. As the wheel experiences normal wear during operation, this design continuously exposes new, sharp diamond crystals to the work surface, ensuring sustained cutting performance and sharpness. This self-replenishing action produces reliable and consistent outcomes that translate directly into measurable improvements in productivity, a reduction in defective parts requiring rework, and enhanced overall quality standards for finished components.

While this wheel can function effectively with handheld applications, it was specifically engineered for integration with CNC grinding machinery, allowing for seamless incorporation into current manufacturing workflows and automated production systems.

Achieving a mirror-polished finish on round cutting tools can substantially extend tool longevity and improve the quality of work performed. Superior surface finishes enable tools to operate at lower temperatures while maintaining sharper cutting edges throughout their service life. When the flute areas of drills and endmills receive fine polishing treatment, machined chips are expelled more readily with minimal frictional resistance and reduced thermal generation. This improved chip evacuation not only enhances the surface finish quality of the final machined workpiece but also directly contributes to extended tool performance and durability.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, a fully coordinated collection of specialized equipment and abrasive consumables designed to optimize rapid and consistent automated tool finishing operations. Each element within this integrated system, including the 3M™ Truing and Dressing Machine and various 3M™ Superabrasive solutions, operates effectively both independently and in conjunction with other components, enabling users to construct a tailored grinding and polishing solution that adapts readily to existing production environments. Furthermore, 3M provides an extensive portfolio of wheel profiles and structural designs specifically developed for round tool grinding applications. The company's comprehensive Superabrasive Wheel lineup encompasses diverse construction methods suitable for general-purpose grinding tasks and CNC machine operations, offered with either cubic boron nitride or diamond abrasive options to meet varied application requirements.
