Product Description
The Mitutoyo 293-677-20 QuickMike micrometer is designed for fast outside-diameter measurement across the 1–2.2" (25.4–55.88 mm) range. It is suitable for machine shops and inspection environments where operators regularly measure shafts, bearing journals, gear hubs, hydraulic rods and turned components.
Its rapid spindle mechanism advances 10 mm (.4") per thimble rotation, allowing the operator to move between different workpiece sizes faster than with a conventional fine-feed micrometer. The measuring system provides .00005" (0.001 mm) resolution and ±.0001" (±2.54 µm) instrumental accuracy.
The display can switch between inch and metric units, making the 293-677-20 practical for production environments where drawings and specifications use different measurement systems. Its ABSOLUTE linear scale retains the origin without requiring a reset every time the micrometer is powered on.
The micrometer uses carbide-tipped measuring faces with a micro-lap finish, a 6.35 mm diameter non-rotating spindle, and a ratchet friction thimble designed for consistent measuring force. Flatness is specified at 0.3 µm, while parallelism is 2 µm (.00008").
For machining environments, the IP65-rated construction provides protection against dust and coolant. The instrument also includes MIN Hold, function lock and Digimatic SPC data output for transferring measurement results to compatible data collection equipment.
A 1" standard bar, one SR44 battery and a fitted plastic case are included for setup and storage.
The 293-677-20 is the inch/metric version in this range. The Mitutoyo 293-667-20 covers 25–55 mm for metric-only requirements, while the 293-676-20 and 293-678-20 cover adjacent inch ranges.

Who This Product Is Best For
The Mitutoyo 293-677-20 is suitable for:
-
Precision machine shops
-
Automotive component and rebuild workshops
-
Pump and compressor service companies
-
Oil and gas machining operations
-
Hydraulic equipment workshops
-
Bearing and shaft inspection
-
Production quality-control departments
-
Calibration and inspection environments
Typical applications include measuring bearing journals, gear hubs, pump shafts, hydraulic rods, turned bushings and other cylindrical components between 1 and 2.2 inches.
It is particularly useful where operators need to switch between inch and metric drawings without changing to a separate micrometer.
How to Use / How It Works
-
Check the reference: Use the supplied 1" standard bar to check the micrometer's origin and reference position.
-
Select the unit: Switch the display between inch and metric according to the measurement requirement.
-
Position the spindle: Use the rapid spindle feed to bring the measuring faces close to the workpiece.
-
Apply measuring force: Use the ratchet friction thimble to complete the measurement with consistent force.
-
Read the result: View the measurement at .00005" or 0.001 mm resolution.
-
Hold or transfer the reading: Use MIN Hold when required, or send the measurement through the Digimatic SPC output to compatible equipment.
For repeat inspection work, verify the reference periodically using an appropriate standard.
