The Starrett 81-T1 Jewel Measuring Gauge is a precision measuring instrument designed for various applications in engineering, manufacturing, and metrology fields. This instrument, manufactured by Starrett, a renowned name in the world of measurement and layout tools, is renowned for its accuracy, durability, and versatility.
The Starrett 81-T1 Jewel Measuring Gauge is a dial type depth micrometer with a fine threaded spindle and a graduated dial. The dial is engraved with precise, clear, and easily readable graduations in inches or millimeters, depending on the user's preference. The gauge's body is made of high-quality, machined steel, providing it with the necessary rigidity and durability for long-term use.
The gauge features a fine threaded spindle that can be adjusted with a knurled knob located at the rear end of the gauge. The spindle is capable of fine adjustments, enabling users to measure depths with high accuracy. The spindle is protected by a jeweled bearing, which reduces friction and ensures smooth operation. This bearing also minimizes the risk of wear and tear, ensuring that the gauge maintains its accuracy over an extended period.
The Starrett 81-T1 Jewel Measuring Gauge comes with an anvil annealed hardened steel anvil and a hardened steel blade. The anvil is designed to provide a stable and secure platform for the gauge's spindle, ensuring accurate and consistent measurements. The hardened steel blade, on the other hand, is used to take measurements by pressing it against the workpiece's surface.
The gauge's dial features a clear and easy-to-read scale, with a pointer that moves across the graduations as the spindle is adjusted. The pointer is held in place by a locking mechanism, which prevents it from moving unintentionally, ensuring the accuracy of the measurement.
The Starrett 81-T1 Jewel Measuring Gauge comes with a protective case, which safeguards the instrument during transportation and storage. This case is made of high-quality materials, ensuring that the gauge remains protected from damage and dust.
