Mitutoyo 368-916 Three Point Two Point Internal Micrometer

Description

The Mitutoyo 368-916 Three-Point Internal Micrometer is a high-precision mechanical tool for measuring internal diameters, also known as bores. The "Holtest" micrometer is part of the Mitutoyo Series 368 and features a three-point contact design that automatically self-centers within the bore for more stable and repeatable measurements. The 368-916 model is sold as a set covering a range of measurements.

Key features

• Measurement range: The model 368-916 set measures internal diameters from 0.275 to 0.5 inches and contains three separate gauge heads for the following sub-ranges:
• 0.275" to 0.35"
• 0.35" to 0.425"
• 0.425" to 0.5"
• High precision: It offers a resolution of 0.0001 inches and accuracy of ±0.0001 inches.
• Self-centering design: The three-point measurement method ensures that the micrometer automatically centers itself within the bore, providing stable and accurate measurements.
• Durable contact points: The measuring contact points are coated with Titanium Nitride (TiN) to provide excellent durability, impact resistance, and long-term precision.
• Blind hole measurement: The design of the contact points allows the micrometer to take measurements at the bottom of blind (flat-bottomed) holes.
• Consistent measuring force: A built-in ratchet stop mechanism applies a consistent force on the hardened-steel spindle, which helps ensure repeatable measurement results.
• Laser-etched scale: The thimble and sleeve are laser-etched to create a clear scale that is easy to read in different lighting conditions.
• Included accessories: The set comes with the three gauge heads, two setting rings (0.35" and 0.5" diameter) for zero-point adjustment, an extension rod for measuring deep holes, and a fitted case.
