Mitutoyo 133-147 Tubular Inside Micrometer (150-175mm, 0.01mm) - Single Rod Type

The Mitutoyo 133-147 Tubular Inside Micrometer is a high-precision, single-rod mechanical measuring tool engineered for accurate internal diameter (ID) measurement of cylinders, bores, pipes, and internal recesses. Operating across a 150 mm to 175 mm measuring range with a 0.01 mm resolution/graduation, this industrial-grade micrometer ensures precise 2-point measurement compliance for metalworking and precision machining.

Featuring carbide-tipped measuring faces, the tool offers superior resistance to wear, maintaining calibration accuracy over extended usage. The micrometer head is styled with a non-glare satin-chrome finish sleeve and thimble, featuring laser-etched graduations for easy reading under shop lighting. An integrated locking clamp allows technicians to freeze readings in position, while the included adjustment key wrench facilitates straightforward zero-point calibration.

Features

• High Precision Measurement: 150–175 mm measuring range with an accuracy of ±0.005 mm (±5 µm).
• Carbide-Tipped Anvils: Wear-resistant carbide measuring faces ensure consistent durability and extended service life.
• Clear Vernier Scale: Satin-chrome sleeve and thimble finish minimizes glare and ensures clear, high-contrast graduation readability.
• Integrated Locking Clamp: Secures the spindle in place to prevent movement while recording measurements.
• Easy Zero-Point Adjustment: Allows quick zero-setting re-calibration by rotating the micrometer head sleeve using the provided key wrench.
• Rigid Single Rod Design: Provides high structural stability during 2-point internal bore check routines.
