Mitutoyo 368-918 3-Point Internal Micrometer Kit, 0.8 to 2" (20.32 to 50.8 mm)

Description

The Mitutoyo 368-918 3-Point Internal Micrometer Kit is an imperial Holtest set designed for measuring the internal diameters of bores and holes. It uses three self-centering anvils to provide accurate and repeatable measurements. The kit includes multiple micrometers to cover a full range from 0.8 to 2.0 inches.

Key features

• Automatic Self-Centering: Features three anvils spaced at 120° intervals that automatically self-center within the bore for stable and accurate alignment and measurement.
• Durable Contacts: Measuring contact points are TiN (titanium nitride) coated for enhanced durability, wear resistance, and impact resistance. The anvils are also carbide-tipped.
• Measurement Range: A kit that collectively measures bores from 0.8 inches to 2.0 inches, utilizing four individual micrometer heads to cover specific sub-ranges within this total span.
• High Accuracy: Provides a high degree of precision with an accuracy specification of \(\pm 0.00015\) inches and a graduation/resolution of 0.0002 inches.
• Consistent Force: Incorporates a built-in ratchet stop mechanism to ensure a constant and uniform measuring force is applied during each use, leading to highly repeatable results between different users.
• Blind Hole Capability: Designed to allow measurements close to the bottom of blind holes due to the specific geometry of the contact points.Included
• Accessories: The comprehensive kit includes an extension rod for deeper holes, two setting rings (1.0" and 1.6") for zero-point calibration, and a fitted carrying case for protection and transport.
• Analog Display: Utilizes a clear, easy-to-read mechanical/analog display for measurements.
• Quality Assurance: Comes with an inspection certificate to verify that the tool meets required manufacturing and accuracy standards.
