Description

The Mitutoyo 511-853-20 Micrometer Head Bore Gauge is an inch-based mechanical bore gauge designed for high-accuracy measurement of inner diameters ranging from 2.4 to 4.0 inches. It is part of the Mitutoyo 511 Series of bore gauges that use a micrometer head to set the master dimension.

Key features

• Measurement range: 2.4 to 4.0 inches.
• Graduation:This gauge is equipped with a dial indicator with 0.0001" graduations.
• Accuracy: 0.00008" (2 \(\mu \)m), according to higherprecision.com.
• Repeatability: 0.00002" (0.5 \(\mu \)m), according to industrybuying.com.
• Anvils: The bore gauge comes with a set of interchangeable anvils and sub-anvils that allow for accurate dimensional setting across the full measurement range. They are constructed of alloy steel with carbide-tipped measuring faces for durability.
• Handle design: A large, hollow-structured grip reduces heat transfer from the operator's hand by 50%, improving measurement accuracy.
• Protective cover: The dial indicator is protected by a rugged cover
• Extensions: Optional extension rods can be purchased separately for measuring deeper bores.
