Mitutoyo 293-679-20 | Digital Absolute Micrometer QuickMike | Inch/Metric, Range 3 - 4.2" (76.2 - 106.68 mm)

Part Number: Mitutoyo 293-679-20

The Mitutoyo 293-679-20 QuickMike micrometer moves its spindle 10 mm per turn, making it much faster to switch between part sizes across 3"–4.2" (76.2–106.68 mm). Its ABSOLUTE digital readout and IP65 protection make it suitable for busy machine shops and inspection environments. Request a quote in under a minute: call or WhatsApp +965 9807 4888.

On a standard micrometer, the spindle advances 0.5 mm per turn, requiring many turns when moving between different measurement sizes. The Mitutoyo 293-679-20 QuickMike advances 10 mm per revolution across its 30 mm working range of 3"–4.2" (76.2–106.68 mm).

This faster spindle movement is useful in high-mix inspection environments where operators measure several different diameters in succession. The non-rotating spindle contacts the workpiece without twisting, while the ABSOLUTE linear encoder provides 0.00005" / 0.001 mm resolution without requiring origin resetting at power-on.

With IP65 protection against dust and coolant, the micrometer is designed for practical shop-floor use. It is suitable for CNC machine shops, power and desalination plant maintenance teams, oil and gas service contractors, and quality-control departments across Kuwait.

For accurate results, allow the Mitutoyo 293-679-20 QuickMike and the workpiece to reach the same temperature before taking the measurement. Steel expands by approximately 11.5 μm per metre per °C, so temperature differences can affect measurements on larger components.

For smaller parts, consider the Mitutoyo 293-678-20 for 2"–3.2". For a metric-only range, compare the Mitutoyo 293-669-20.

Key Benefits

• Faster changeovers — move from one part size to another in only a few thimble turns

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

• ABSOLUTE encoder — 0.00005" / 0.001 mm resolution without origin reset 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 — twenty times the spindle travel of a standard 0.5 mm-pitch micrometer

Who This Product Is Best For

• High-mix CNC machine shops measuring different diameters throughout a shift

• In-process inspection at machines where coolant and dust are present

• Maintenance teams and QC inspectors checking shafts and pins

• QC departments looking to improve measurement throughput without sacrificing resolution

• Buyers upgrading from standard 0.5 mm-pitch digital micrometers

How to Use

1. Open the spindle quickly using the few-turn QuickMike mechanism.

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

3. Position the measuring faces around the workpiece.

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

5. Read the measurement from the ABSOLUTE digital display or send the value to an SPC system when required.

6. For final precision measurements, allow the micrometer and workpiece to stabilize at the same temperature.

Frequently Asked Questions

What range does the Mitutoyo 293-679-20 QuickMike measure?

It measures 3"–4.2" (76.2–106.68 mm), providing a 30 mm working range.

What makes the QuickMike faster than a standard micrometer?

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

Is the Mitutoyo 293-679-20 suitable for shop-floor use?

Yes. It has IP65 protection against dust and coolant, along with a non-rotating spindle and carbide-tipped measuring faces.

How long does the battery last?

Battery life is approximately 5 years under normal use.

Which QuickMike should I choose if my part is outside the 3"–4.2" range?

Select a QuickMike with a measuring range that covers your required part size. The Mitutoyo 293-678-20 covers 2"–3.2". For metric ranges, compare the Mitutoyo 293-669-20.

Can the Mitutoyo 293-679-20 be recalibrated?

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