Features HIGH-QUALITY MATERIAL: High-precision calipers are made of high-quality aluminum alloy. The surface undergoes anodic oxidation treatment, making it harder, more wear-resistant, good insulator and more durable. EXCELLENT DESIGN: The dovetail gauge is manufactured with CNC machining to ensure accurate measurements. Laser engraved scales provide excellent clarity and durability. The caliper offers both metric and imperial scales to meet different needs PRACTICAL TOOL: The dovetail jig template allows you to easily make multiple precise dovetail joints, and the block size can be easily and accurately controlled by adjusting the position of the teeth and cutter. It can also be used for setting VERSATILITY: Caliper configuration includes metric tenon scale 5 6 8 10 12mm and imperial scale 3/16, 1/4, 5/16, 3/8, 1/2 inch. The measurement height scale has 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 16mm and imperial scale 1/8, 3/16, LASER GRAVATED SCALES: For reliable accuracy, the scales are laser engraved and offer excellent clarity and durability.
