Facilitates Effective Truing of Superabrasive Wheels
As operators know well, truing and dressing abrasive wheels are crucial to their performance. The 3M™ DSD Truing Tool helps operators save time and maximum wheel performance by making the truing process easier and more accurate.

While dressing sticks typically rid the wheel of debris and refresh the abrasive grain to avoid glazing and maintain sharpness, the DSD Truing Tool helps operators shape and dress the wheel in one step so that it runs smoothly and consistently. When the wheel is out of balance and starts to wobble, proper shaping restores concentric balance, meaning the wheel surface is precisely concentric with the spindle. Moreover, a truing tool brings the wheel back to its original shape with even surfaces. A concentric, precisely shaped wheel eliminates wobbling or shaking at high speeds and results in smooth, precise performance and consistent finishes.

Making the Most of Your Truing Tool
For optimum performance, securely position the 3M™ DSD Truing Tool with a 3M™ Holding Block (sold separately). Used together, the truing tool and compatible holding block ensure more uniform contact and pressure, allowing operators to swiftly and effectively true their abrasive wheels with consistent, precise results.

Truing tools from 3M are available in four sizes for use on wheels of varying widths:


1/4" tool – Use on diamond or CBN wheels with up to 1/4˝ width
3/8" tool – Use on diamond or CBN wheels with up to 3/8˝ width
1/2" tool – Use on diamond or CBN wheels up to 5/8˝ width
5/8" tool – Use on large wheels including centerless (use on O.D. of the tool)




When the tool is in use, it is necessary to engage a moderate to fast tool feed to eliminate unnecessary tool wear. Running the truing tool at too slow a speed will wear the tool without properly modifying the wheel. An active sparking interface between tool and wheel is the desired effect. Likewise, the appropriate wheel downfeed must be set for successful shaping, and is determined by the hardness and grit size of the wheel. See the tool instructions for tool positioning, recommended downfeeds, and directions for centerless wheels.

Important Safety Precautions
The use of grinding wheels requires extra safety precautions, and this applies when using truing tools as well. It is recommend that operators always wear eye protection and use good grinding practices regarding ventilation.

An Important Task
Truing and dressing are important maintenance processes required to keep expensive superabrasive grinding wheels cutting consistently. These applications also help you extend the lifespan of your superabrasive wheels and protect the grinding tools that run them. Recently trued and dressed grinding wheels have fresh cutting edges that grind quickly and evenly on metal surfaces, which increases throughput and improves quality. Thus, effective truing and dressing should be an integral part of any workshop that uses superabrasive wheels regularly.
