This diamond router bit is equipped with an extra-long white nylon guide cover (115mm diameter), specially engineered to improve profiling accuracy while protecting your stone surface.

Unlike metal guide bearings or dark plastic covers that may leave marks, the non-staining white nylon material ensures your granite, marble, quartz, or engineered stone remains clean and free from discoloration during operation. This is especially important for light-colored or high-end materials where surface appearance matters.

The extended 115mm diameter design provides a larger contact area against the stone edge, helping stabilize the tool during routing. This added stability assists in:

✔ Maintaining a straighter, more uniform profiled edge
✔ Reducing unwanted vibration or wobble
✔ Improving control for smoother, more consistent results
✔ Minimizing the risk of accidental surface damage

Whether you are a professional fabricator or a serious DIY user, this thoughtful design feature helps deliver cleaner edges, better accuracy, and more professional finishes with less effort.
