Product Summary
The Mitutoyo 293-676-20 QuickMike micrometer measures from 0 to 1.2 inches (0–30.48 mm) and switches between inch and metric readings on the display. Its rapid spindle feed moves 10 mm (.4") per thimble rotation, while the instrument provides .00005" (0.001 mm) resolution and ±.0001" (±2.54 µm) instrumental accuracy. The IP65-rated design helps protect against dust and coolant, while MIN Hold and Digimatic SPC output support production inspection. Contact General Tech Saudi Arabia for pricing and availability.
Product Description
The Mitutoyo 293-676-20 QuickMike micrometer is designed for fast and precise outside measurement of components from 0 to 1.2 inches (0–30.48 mm). Its inch/metric switching makes it practical for workshops where operators work with both imperial and metric drawings.
Unlike a conventional micrometer with a slower spindle movement, the QuickMike mechanism advances 10 mm (.4") per thimble rotation. This rapid feed allows the measuring faces to move quickly across the 0–30.48 mm range, reducing the amount of thimble rotation required during repetitive inspections.
The instrument provides .00005" (0.001 mm) resolution and ±.0001" (±2.54 µm) instrumental accuracy. The measuring faces are carbide-tipped with a micro-lap finish, while the 6.35 mm diameter non-rotating spindle helps maintain controlled contact with the workpiece.
The 293-676-20 uses an ABSOLUTE linear scale, so the origin does not need to be reset each time the micrometer is powered on. Its LCD uses 10 mm character height for easy reading, and the instrument includes MIN Hold for retaining the minimum measured value during suitable inspection procedures.
The micrometer also includes a ratchet friction thimble with a specified measuring force of 5–12 N. Flatness is specified at 0.3 µm, while parallelism is 2 µm (.00008").
For machining environments, the IP65 rating provides protection against dust and coolant. Digimatic SPC output allows compatible measurement data to be transferred to inspection or data-collection systems.
The 293-676-20 is supplied with an SR44 battery and fitted plastic case. Unlike some larger QuickMike models, it does not require a separate standard bar because the zero reference can be set using the closed measuring faces.
For metric-only applications, the Mitutoyo 293-666-20 covers 0–30 mm. For larger inch/metric measurements, the 293-677-20 covers 1–2.2 inches.

Who This Product Is Best For
The Mitutoyo 293-676-20 is suitable for:
-
Precision machine shops
-
Automotive workshops
-
Oil and gas machining operations
-
Aerospace MRO teams
-
Hydraulic equipment workshops
-
Production inspection departments
-
Quality-control teams
-
General maintenance workshops
Typical applications include measuring shafts, pins, bushings, valve stems, shims, turned components and thread-rolled blanks within the 0–1.2" range.
It is particularly useful for workshops that receive both inch and metric drawings, allowing operators to switch measurement units without using a separate micrometer.
How to Use / How It Works
-
Clean the measuring faces: Remove chips, dust, oil or coolant from the contact surfaces and workpiece.
-
Set the reference: Close the measuring faces using the ratchet and verify the zero position.
-
Select the unit: Switch between inch and metric according to the drawing or inspection requirement.
-
Position the spindle: Use the rapid-feed mechanism to bring the measuring faces close to the component.
-
Apply measuring force: Complete the measurement using the ratchet friction thimble for controlled force.
-
Read or hold the value: Read the displayed result or use MIN Hold when the inspection requires the minimum value.
-
Transfer the result: Send the measurement through the Digimatic SPC output when compatible data collection equipment is being used.
For repeat inspection work, verify the reference regularly using an appropriate measurement standard.
Frequently Asked Questions
What is the measuring range of the Mitutoyo 293-676-20?
The measuring range is 0–1.2 inches (0–30.48 mm).
Can the 293-676-20 display both inch and metric measurements?
Yes. The 293-676-20 supports inch/mm switching directly on the display with .00005" (0.001 mm) resolution.
How fast is the QuickMike spindle?
The spindle advances 10 mm (.4") per thimble rotation, allowing rapid movement across the measuring range.
What accuracy does the 293-676-20 provide?
The specified instrumental error is ±.0001" (±2.54 µm). Flatness is 0.3 µm and parallelism is .00008" (2 µm).
Does the 293-676-20 have an ABSOLUTE scale?
Yes. Its ABSOLUTE linear scale retains the origin through power-off, reducing the need for repeated origin setting.
Is the micrometer suitable for coolant environments?
The 293-676-20 has an IP65 rating, providing protection against dust and coolant under the specified rating conditions.
What is included with the product?
The product includes one SR44 battery and a fitted plastic case. A separate standard bar is not required because the zero reference is set using the closed measuring faces.
What is the difference between the 293-676-20 and 293-666-20?
The 293-676-20 is the inch/metric version covering 0–1.2" (0–30.48 mm). The 293-666-20 is the metric-only counterpart covering 0–30 mm.
What QuickMike should I choose for larger parts?
For measurements above 1.2", the 293-677-20 covers 1–2.2", while larger QuickMike models cover ranges such as 2–3.2" and 3–4.2". Select the model based on the required measuring range.
Is there a newer version of the 293-676-20?
The -20 designation refers to the 2019 IP65 generation. Mitutoyo America lists 293-676-22 as a newer US listing. Contact General Tech to confirm the version currently available before ordering.
