Why this bit helps you work smarter

• Precise 90° V-groove creates clean, crisp lines with excellent legibility for signs and engravings.
• Top bearing enables template-following for repeatable patterns and consistent results.
• Compatible with hand-held, table-mounted, and CNC routers for adaptable workflows.

Practical tips for best results

Test cuts on scrap stock to dial in depth and preview how the groove will look in your chosen material. When using templates, verify that the bearing height aligns with your fixture for uniform lines. For multi-pass work, start with shallow passes and gradually deepen to reach the final groove width, preserving edge integrity and minimizing tear-out.
