3M™ Diamond and CBN Wheels and Tools, 685DC TRIZ DIA PLSNG WHL 1A8, 4X5/16X1-1/4, 10 MIC, 1 ea/Case

3M has developed an innovative advancement in tool finishing through the introduction of proprietary bonding technology integrated into the 3M™ Trizact™ Diamond Polishing Wheel 685DC. This specialized bonding formulation delivers exceptional surface quality outcomes while effectively preventing any alterations to tool profiles or cutting edge geometry, all while preserving the refined polished surface characteristics. Engineered with particular attention to the finishing requirements of drill flutes and endmill surfaces, this wheel merges the performance advantages of traditional resin-bonded diamond wheels with the controlled finishing attributes of non-woven abrasive solutions, creating a hybrid tool that enables rapid material removal alongside sufficient structural integrity for precision truing, dressing procedures, and accurate conformance to intricate tool contours.

The wheel incorporates diamond particles that are uniformly distributed throughout its entire structure. During the grinding process, the wheel's resin matrix gradually wears away, continuously revealing new, undulled diamond crystals to engage with the workpiece surface. This self-sharpening characteristic results in reliable, uniform performance characteristics that enhance operational efficiency, reduce scrap rates and the need for rework operations, and improve the overall quality standards of finished components.

Although this wheel can be utilized with handheld grinding equipment, it was specifically engineered for integration with CNC grinding machinery, providing seamless compatibility with contemporary manufacturing environments and existing production workflows.

Achieving a mirror-quality polish on cylindrical cutting tools can substantially extend tool longevity and enhance finished part quality. Superior surface finishes help tools maintain lower operating temperatures and preserve edge acuity during operation. A highly refined surface texture in the flute passages of drills and endmills facilitates the smooth evacuation of chips produced during cutting, minimizing frictional resistance and thermal buildup. Enhanced chip evacuation efficiency not only produces superior surface finishes on workpieces but also contributes meaningfully to extended tool service life.

The 3M™ Trizact™ Diamond Polishing Wheel 685DC functions as a core component within the comprehensive 3M™ Cutting Tool Grinding and Polishing System, which represents a carefully coordinated selection of machinery and consumable products developed to deliver rapid, reliable, and fully automated tool grinding and finishing capabilities. Each element within this integrated system, encompassing the 3M™ Truing and Dressing Machine and 3M™ Superabrasives product line, operates effectively as standalone equipment or can be combined with other components to establish a fully integrated grinding and polishing solution that readily accommodates integration with the majority of established production operations. Furthermore, 3M provides an extensive selection of wheel profiles and design configurations specifically optimized for cylindrical tool grinding applications. The 3M Superabrasive Wheels portfolio encompasses numerous construction variants suitable for general machining operations and CNC machine applications, offered with either cubic boron nitride or diamond abrasive materials.
