Adjustable heightdepth gauge for precise height adjustments of router bits and table saw blades, enabling cutting depth and accuracy in woodworking projects. Fast and accurate setting reduces setup time and improves repeatability compared with traditional setup blocks and rulers, delivering repeatable results with less recalibration. Lightweight yet sturdy CNCmachined aluminum alloy construction with an anodized finish for durability, while keeping the scale easy to read. Wide applications for DIY enthusiasts and professionals: simplifies the setup process and helps achieve precise cuts across a range of projects. Use scenarios: Set router bit depth for precise edge profiles, grooves, or trims on cabinetry and furniture. Align table saw blade height to achieve consistent crosscuts or groove depths across multiple pieces. Reproduce identical depth settings across a batch of parts for repeatable production runs.
