Product Overview
The Mitutoyo 293-676-20 Quickmike is an ABSOLUTE Digimatic micrometer from Mitutoyo's Quickmike Series 293, developed for rapid dimensional measurement across a wider range than a conventional micrometer.
It provides a 0–1.2" (0–30.48 mm) measuring range, with a 10 mm spindle feed per thimble rotation. This feed rate is approximately 20 times faster than a conventional micrometer, allowing operators to move between different workpiece sizes quickly without repeatedly rotating the thimble.
The micrometer uses a non-rotating Ø6.35 mm spindle, which helps reduce torsion on softer workpieces. A redesigned ratchet friction thimble supports one-handed operation while maintaining a constant measuring force of 5–12 N.
Its ABSOLUTE linear scale retains the origin throughout the life of the battery, eliminating the need to reset the origin every time the micrometer is switched on. The design also has no spindle-movement speed limitation during measurement.
For machining environments, the IP65 coolant-proof protection helps protect the instrument against splashing coolant, oil, and dust. The large LCD has a 10 mm character height and provides functions including HOLD, MIN hold, and function lock.
The 293-676-20 has a resolution of 0.00005 in / 0.001 mm and an accuracy of ±0.0001 in. Its carbide-tipped measuring surfaces feature a micro-lap finish, while the instrument supports SPC data output for inspection and quality-control workflows.
The micrometer operates on one SR44 battery, with an approximate battery life of 5 years under normal use.
For users requiring a larger measuring range, the 293-677-20 covers 1–2.2" (25.4–55.88 mm) in the same Quickmike series.

Who This Product Is Best For
The Mitutoyo 293-676-20 is suited for:
- Machine shops measuring different part sizes quickly
- Shop-floor quality control around cutting fluid and dust
- Inspection teams requiring rapid dimensional measurements
- Manufacturing and machining operations
- Quality-control departments using SPC data collection
- Operators who need a wider measuring range than a conventional 25 mm micrometer
How to Specify & Use It
- Switch on the 293-676-20. The ABSOLUTE scale means an origin setting is not normally required.
- Verify the zero point before carrying out critical measurements.
- Position the measuring faces against the workpiece using the ratchet thimble to maintain constant measuring force.
- Read the measurement on the LCD and use HOLD or MIN hold when required.
- Transfer measurement data through the SPC data output when required for inspection or quality-control systems.
Frequently Asked Questions
What measuring range does the Mitutoyo 293-676-20 cover?
It measures from 0 to 1.2" (0 to 30.48 mm).
How fast is the Quickmike spindle feed?
The spindle feeds 10 mm per thimble rotation, which is approximately 20 times faster than a conventional micrometer.
Do I need to set the origin every time I switch it on?
No. The ABSOLUTE linear scale retains the origin throughout the life of the battery, so repeated origin setting is not required.
Can the 293-676-20 be used around coolant and dust?
Yes. It has IP65 protection, making it suitable for machining environments where splashing coolant, oil, and dust may be present.
What accuracy does the 293-676-20 provide?
The stated accuracy is ±0.0001 in, excluding the quantizing error of ±1 count.
What is the resolution?
The resolution is 0.00005 in / 0.001 mm.
What type of spindle does the micrometer use?
It has a Ø6.35 mm non-rotating spindle with a 10 mm feed per revolution.
What is the measuring force?
The constant-force ratchet provides a measuring force of 5–12 N.
Does the 293-676-20 have data output?
Yes. It provides SPC data output for transferring measurement data to compatible inspection or quality-control systems.
How long does the battery last?
The instrument uses one SR44 battery and has an approximate battery life of 5 years under normal use.
Does the 293-676-20 include a setting standard?
No. The 0–30 mm / 0–1.2" model does not require a setting standard.
