Mitutoyo 293-668-20 Digital Absolute Micrometer QuickMike 50-80mm

Part Number: Mitutoyo 293-668-20

The Mitutoyo 293-668-20 QuickMike ABSOLUTE digital outside micrometer provides a 50–80 mm measuring range with a 10 mm-per-turn spindle, allowing operators to switch between different part sizes much faster than with a conventional micrometer. Its ABSOLUTE digital readout, non-rotating spindle, carbide-tipped measuring faces, and IP65 protection make it suitable for demanding shop-floor measurement environments.

A standard micrometer typically advances its spindle 0.5 mm per turn, requiring many rotations when changing between different measurement sizes. The Mitutoyo 293-668-20 advances 10 mm per revolution, providing twenty times the spindle travel across its 50–80 mm working range.

The fast spindle is useful in high-mix inspection environments where operators measure multiple diameters in succession. The non-rotating spindle contacts the workpiece without twisting, while the ABSOLUTE linear encoder provides 0.001 mm resolution without requiring re-zeroing at power-on.

IP65 protection helps protect the instrument against dust and coolant, making it suitable for measurement near machining operations. Typical applications include QC inspection, calibration laboratories, fabrication and machining workshops, and maintenance work supporting Kuwait's oil, gas, and utilities sectors.

Keep the contact faces clean and store the Mitutoyo 293-668-20 in its case between jobs. In hot Kuwait workshops, allow the workpiece to cool and let the micrometer and part reach the same temperature before taking a final precision measurement.

For larger parts, the Mitutoyo 293-669-20 covers 75–105 mm. For an inch-version QuickMike, compare the Mitutoyo 293-678-20.

Key Benefits

• IP65 protection — resistance to dust and coolant for shop-floor use.

• ABSOLUTE encoder — 0.001 mm resolution with no origin reset required at power-on.

• Non-rotating spindle — helps prevent twisting or scuffing of finished surfaces.

• Long battery life — approximately 5 years under normal use.

• 10 mm per turn — provides twenty times the spindle travel of a standard 0.5 mm-pitch micrometer.

• Faster changeovers — move between different part sizes in only a few turns.

Who This Product Is Best For

• High-mix CNC shops measuring multiple diameters during a shift.

• In-process inspection applications where dust and coolant are present.

• Maintenance teams in oil and gas workshops checking shafts, pins, and similar components.

• QC departments seeking faster measurement throughput without sacrificing resolution.

• Buyers upgrading from conventional 0.5 mm-pitch digital micrometers.

How to Use

1. Open the spindle quickly using the thimble to reach the required measurement range.

2. Check the zero position against the anvil or supplied setting standard.

3. Position the workpiece between the measuring faces.

4. Close the spindle onto the part using the ratchet for consistent measuring force.

5. Read the value on the digital display or transfer the measurement to an SPC system where supported.

Frequently Asked Questions

What range does the Mitutoyo 293-668-20 QuickMike micrometer measure?

It measures from 50–80 mm, providing a 30 mm working range.

What makes QuickMike faster than a standard micrometer?

The spindle advances 10 mm per revolution instead of approximately 0.5 mm per revolution on a standard micrometer, significantly reducing the number of thimble turns required when changing between part sizes.

Is the Mitutoyo 293-668-20 suitable for shop-floor use?

Yes. Its IP65 protection helps protect against dust and coolant, while the non-rotating spindle and carbide-tipped measuring faces support practical shop-floor measurement.

How often does the battery need changing?

The battery life is approximately 5 years under normal use.

Which QuickMike should I choose if my part is outside 50–80 mm?

Choose the model according to the required measurement range. The Mitutoyo 293-667-20 covers 25–55 mm, while the Mitutoyo 293-669-20 covers 75–105 mm. For inch-range applications, compare the Mitutoyo 293-678-20.

Can it be recalibrated?

Yes. The Mitutoyo 293-668-20 can be periodically recalibrated through an ISO/IEC 17025-accredited calibration service to maintain measurement traceability.
