Product Overview
The Mitutoyo 293-669-20 Quickmike is a metric ABSOLUTE Digimatic micrometer from Mitutoyo's Quickmike Series 293, designed for machine shops, inspection teams, and production environments where fast and repeatable dimensional measurement is important.
Its 75–105 mm measuring range and 30 mm measurement span allow users to measure a wider range of component sizes without changing instruments as frequently as with conventional micrometers. The Quickmike mechanism provides 10 mm of spindle feed per thimble rotation, making operation approximately 20 times faster than a conventional micrometer.
The micrometer uses a non-rotating Ø6.35 mm spindle, which helps reduce torsion on softer workpieces during measurement. Its redesigned ratchet friction thimble provides a constant measuring force of 5–12 N and supports convenient one-handed operation.
The ABSOLUTE linear scale retains the origin throughout the battery life, eliminating the need to reset the zero position every time the instrument is switched on. The design also places no speed limit on spindle movement, supporting rapid measurement workflows.
For machining environments, the IP65 coolant-proof construction provides protection against splashing coolant. The large 10 mm-high LCD provides clear measurement readings and includes useful functions such as HOLD, MIN hold, function lock, and a low-voltage alarm.
The 293-669-20 has a resolution of 0.001 mm and an accuracy of ±3 µm, excluding the quantizing error of ±1 count. Carbide-tipped measuring surfaces with a micro-lap finish support consistent contact with the workpiece.
The micrometer uses one SR44 battery, providing approximately five years of battery life under normal use. It also supports SPC data output for integration into digital inspection and quality-control workflows.

Who This Product Is Best For
The Mitutoyo 293-669-20 is suited for:
- Machine shops measuring components across different sizes
- Shop-floor quality-control teams working around cutting fluid, coolant, oil, and dust
- Production inspection teams requiring fast dimensional checks
- Quality engineers using SPC data collection
- Users who need faster operation than a conventional micrometer provides
How to Specify & Use
- Switch on the 293-669-20. The ABSOLUTE scale retains its origin, so repeated origin setting is not required.
- Before critical measurements, verify the micrometer against the supplied setting standard or appropriate reference.
- Position the measuring faces on the workpiece and use the ratchet friction thimble to apply the correct constant measuring force.
- Read the measurement from the LCD and use HOLD or MIN hold when required.
- Use the SPC data output when measurement results need to be transferred to an inspection or quality-control system.
Frequently Asked Questions
What measuring range does the Mitutoyo 293-669-20 cover?
The 293-669-20 measures from 75 to 105 mm and provides a 30 mm measuring range.
