Analog display for simple, battery-free readings Dial readout: parallel What this measuring instrument does - Used to measure the internal dimensions of holes and features of various diameters and depths using a comparative method. - Designed for accurate inside measurements in woodworking and related crafts. Key benefits - Battery-free operation with an analog display for quick, straightforward readings. - Parallel dial design helps with easy cross-checking and improves measurement confidence. - Compact and simple to use in small shops, drafting areas, or on-site carpentry tasks. - Suitable for verifying bore sizes and ensuring components fit together before assembly. Compatible crafts and applications - Carpentry and woodworking projects requiring precise hole and recess measurements. - Quality checks in hobbyist workshops to confirm hole diameters and depths match specifications. - Preparatory measurements for hardware installation, dowel positions, and joinery fits. Use scenarios - Scenario 1: Before inserting screws or fittings, measure a series of holes to confirm diameters and depths align with hardware specifications. - Scenario 2: Check bore depths across a set of wooden parts to ensure uniformity before assembly, reducing rework. - Scenario 3: In a small workshop, compare internal dimensions of multiple components to verify consistency and interchangeability.
