Mitutoyo 368-766 Holtest 3 Point Internal Micrometers 20 to 25mm range

Description

The Mitutoyo 368-766 Holtest (Type II) is a 20 to 25mm, three-point internal micrometer for measuring the inside diameter of bores. It is a mechanical (non-digital), self-centering micrometer that provides accurate and repeatable measurements.

Key features

• Self-centering design: The micrometer uses three alloy-steel anvils, evenly spaced at 120°, that automatically center themselves in the bore. This provides true alignment with the axis of the bore, resulting in accurate and repeatable measurements.
• Constant force ratchet stop: This mechanism ensures a consistent measuring force is applied to the workpiece, eliminating variations in readings between different operators.
• Blind-bore capability: The design of the micrometer allows you to take measurements near the bottom of blind (or "through") holes.
• Durable construction: The anvils are made from hardened alloy steel, offering durability for a more economical tool compared to titanium-coated versions.
• Laser-etched scale: The scale on the thimble and sleeve is laser-etched to improve readability in various conditions.
• Case included: The micrometer comes in a fitted plastic case for storage and protection.
