Precise, durable caliper for reliable measurements in the workshop, garage, or lab. Key benefits Accurate results: Measures length, depth, thickness, and inner and outer diameters of cylinders with a measuring range of 150 mm and accuracy up to 0.02 mm, so you get repeatable, trusted readings. Easy to read: Exquisite, easy-to-read scale reduces eye strain and speeds up measurement and verification tasks. Built to last: Solid carbon steel construction resists wear and maintains measuring stability for long-term use. Versatile: One tool replaces multiple gauges—internal and external jaws plus depth capability—saving time and reducing tool clutter. What this caliper solves Eliminates guesswork from machining, fitting, and repair jobs by delivering precise, consistent measurements. Reduces rework and material waste caused by inaccurate sizing. Speeds inspection and setup by providing clear graduations and a full 150 mm measuring range. Specifications and performance Functions: measurement of length, depth, thickness, inner diameter and outer diameter of cylinders. Measuring range: 150 mm. Accuracy: up to 0.02 mm. Material: carbon steel. Scale: finely graduated, easy-to-read scale for quick visual readings. Typical applications Metalworking and machining: set up parts and verify tolerances on shafts, holes and flanges. Automotive repair and maintenance: check bearing bores, brake component thickness and shaft diameters during service and rebuilds. Woodworking and DIY projects: measure tenons, drilling depths and fit dimensions where precision is required. User tips Clean measuring surfaces before use to preserve accuracy. Use steady, even pressure when taking readings to avoid small deflections. Store in a protective case or dry area to prevent corrosion and maintain the calibrated feel. A compact, accurate measuring tool that combines the essential functions needed for professional and hobbyist measurement tasks without complexity.
