Mitutoyo 368-913 Holtest Micrometer Set, 3-point, 20 to 50 mm

Description

The Mitutoyo 368-913 Holtest Micrometer Set is a high-precision tool designed for measuring the internal diameters of holes and bores. The set features a three-point measurement system with self-centering anvils, ensuring stable and repeatable measurements.

Key features

• Measurement range: The set measures a range of 20 to 50 mm, which is achieved through a set of four individual gauges. The specific gauges included measure 20–25 mm, 25–30 mm, 30–40 mm, and 40–50 mm.
• Accuracy and resolution: It offers a resolution of 0.005 mm and a measurement accuracy of \(\pm 3\,\mu \)m (\(\pm 0.003\) mm).
• Durability: The measuring points are coated with titanium nitride (TiN) for excellent durability and impact resistance
• .Measurement near blind holes: The contact point geometry allows measurements to be taken close to the bottom of blind holes.
• Constant measuring force: The ratchet-stop mechanism applies a constant measuring force to ensure consistent and accurate readings.
• Included accessories: The set typically includes two setting rings for zero-point adjustment and an extension rod for measuring deep holes. It is supplied in a fitted case for storage and protection.
• Display: It is a non-digital, analog model with a laser-etched scale for easy reading.
