Mitutoyo 368-915 Holtest Micrometer Set, 3-point, 100 to 200 mm

Description

The Mitutoyo 368-915 Holtest Micrometer Set is a three-point, self-centering internal micrometer for accurately measuring the inside diameter of bores in the 100–200 mm range. The set comes with four individual gauges, two setting rings, and an extension rod for deeper holes. The entire set is delivered in a fitted wooden case.

Key features

• Three-point contact: The self-centering design uses three anvils spaced 120° apart, ensuring repeatable, accurate measurements.
• Titanium-coated contact points: The measuring pins are coated with Titanium Nitride (TiN) to provide superior durability and impact resistance.
• Blind hole measurement: The contact point geometry allows for measuring the diameter of a blind hole right down to the bottom (for models under 100 mm).
• Ratchet stop: The ratchet stop mechanism helps ensure consistent measuring force with every use, which is critical for achieving accurate results.
• Included accessories: The set comes complete with four gauges for the different measurement ranges, two setting rings (125 mm and 175 mm) for calibration, and an extension rod for deep holes.
• Build quality: This non-digital bore micrometer set is supplied in a fitted wooden case, appropriate for larger-range Holtest models.
