Part No. 293-677-20
Product Overview
The Mitutoyo 293-677-20 is a Quickmike ABSOLUTE Digimatic coolant-proof micrometer covering 1 - 2.2" (25.4 - 55.88 mm). Its spindle feeds 10 mm per thimble rotation, making it approximately 20 times faster than a conventional micrometer and allowing parts of different sizes to be measured quickly. Each model provides a 30 mm / 1.2" measuring range instead of the usual 25 mm.
The non-rotating spindle helps reduce torsion on softer workpieces, while the redesigned ratchet friction thimble supports one-handed measurement with a constant measuring force of 5 - 12 N. The ABSOLUTE linear scale retains the origin throughout battery life, eliminating the need to reset the origin every time the micrometer is switched on.
With IP65 protection, the 293-677-20 is suitable for machining environments where splashing coolant, oil and dust may be present. Its large 10 mm-high LCD provides clear readings and includes HOLD, MIN hold and function-lock functions.
If a different measuring range is required, the Mitutoyo Quickmike Series 293 also includes the 293-678-20, which covers 2 - 3.2" (50.8 - 81.28 mm).
Key Benefits
- 1 - 2.2" (25.4 - 55.88 mm) measuring range for a wider range of part sizes.
- 10 mm spindle feed per revolution for approximately 20x faster measurement than conventional micrometers.
- ABSOLUTE linear scale retains the origin, eliminating repeated zero-setting.
- IP65 protection for use around coolant, oil and dust in machining environments.
- Non-rotating spindle helps reduce torsion on softer workpieces.
- Ratchet friction thimble provides one-handed operation with constant measuring force.
- Large 10 mm-high LCD for clear digital readings.
- HOLD and MIN hold functions help capture measurements during inspection.
- Approx. 5-year battery life under normal use.
- SPC data output supports digital measurement-data collection.
- Genuine Mitutoyo stock with free UAE-wide shipping.
Who This Product Is Best For
- Machine shops measuring parts of different sizes quickly and efficiently.
- Shop-floor quality-control teams working around cutting fluid, coolant and dust.
- Inspection departments requiring repeatable dimensional measurements.
- Quality engineers who need SPC data output from a digital micrometer.
- Users measuring softer workpieces where a non-rotating spindle can help reduce torsion.
- Operators needing faster measurement than conventional 25 mm-range micrometers.
How to Specify & Use It
- Confirm that the 1 - 2.2" (25.4 - 55.88 mm) measuring range suits the application.
- Switch on the 293-677-20. The ABSOLUTE scale retains the origin, so repeated origin setting is not required.
- Verify the micrometer against the supplied setting standard before critical measurement work.
- Position the measuring faces on the workpiece and use the ratchet friction thimble to apply constant measuring force.
- Read the measurement on the large LCD and use HOLD or MIN hold when required.
- Use the SPC data output when measurement values need to be transferred to a compatible data-collection system.
Frequently Asked Questions
What range does the Mitutoyo 293-677-20 measure?
It measures from 1 - 2.2" (25.4 - 55.88 mm).
How fast is the Quickmike compared with a standard micrometer?
The spindle feeds 10 mm per thimble rotation, making it approximately 20 times faster than conventional micrometers.
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 293-677-20 be used around coolant and dust?
Yes. It has IP65 protection and is designed for use in machining environments where splashing coolant may be present.
What is the accuracy of the 293-677-20?
The specified accuracy is ±0.0001 in, excluding the quantizing error of ±1 count.
What is the measuring force?
The constant-force ratchet provides a measuring force of 5 - 12 N.
Does it include a setting standard?
Yes. The micrometer is supplied with a setting standard, battery and box.
Does the micrometer support SPC data output?
Yes. The 293-677-20 provides SPC data output for compatible measurement-data collection systems.
